Re: FE test update, 27th June, 2013

Glad to see you are finally enjoying your ride after some time!

Just regarding the RC cam and the scratches, Can you post up better pics? Is there a macro setting or text setting?
I'm wondering if these cams get reground and/or welded then lose their hardness layer, This cam never goes back into the hardening process due to whatever reason, Then straight out the door to RC and eventually onto customers.
Another reason could be a dirty engine when assembled and lack of clean parts, Yet another reason could be dirty oil and leaving the oil in for too long when running in.
I'm not making excuses for anyone but there are a couple other trains of thought to that situation.

When you are testing with the Yoshi, You have changed too many parameters (CDI's, Cams) to compare against other engine configuration so it will be just a comparison against???

Are there any plans for the future?
Any thought about upgrading your carb to a proper performance type?

Re: FE test update, 27th June, 2013

As always thanks for your inputs Mik.

As far as changing too many parameters in my bike is concerned, just for your reference the current set up is running with stock cam, CDI, FFE and 15T. The only major thing that will change in the next test will be: 14T, FFE (Yoshi) and may be ignition cable. More or less all the riders who are on 14T have a fair idea about how our respective ride performs with the set up. I wanted to try 15T to see whether with the increase in power my ride is good enough for long distance touring which frankly it is. As far as comparo is concerned more or less the set up will remain the same except the front sprocket changed to stock 14T.

Regarding the parameters you have mentioned behind the scratch marks on the camshaft: The engine oil was new and run-in happened only for 500 kms. Then fresh oil was put in along with new oil filter. The last time we checked the engine oil when the head was opened, it was in good shape and golden greenish colour. If dirty engine oil was the reason then the stock engine's run-in was followed using the factory recommended break-in style with the mineral oil not being changed till the 1st 1000 kms. So logically the stock cam should have had more scratch marks after clocking 26,000 + kms on it. I am no expert in metallurgy so i really cannot comment in this regard.

Unfortunately i have sent out the cam for testing so that i can get the profile, lift and other data which i feel will give us a clear idea regarding how the RC Cam works and what after effects can be expected on the stock valve train system. Once i get hold of the cam i shall try and take a better close up though with my phone cam i really don't know how clear would it be.

I had a chat with PSR Ji regarding the same and he felt that possibly due to the nature of the design of the cam the lobes are more in contact with the rocker arms for a longer duration in order to delay/advance the closing and opening of the valves which has resulted the scratch marks. One thing is for certain: if a generic rider is looking for performance and refinement for some reason the profile the RC cam has is not worth the headache. As per my requirement the only thing i wanted was a better top end especially for highway rides which now finally with the set up i have, it is delivering exactly what i had in mind without the earlier drawbacks i had witnessed with my souped up ride. I have no intentions of breaking any land speed record, just wanted a touring set up as i have mentioned before.


Future mods?

I had a chat with the guys from Motozone and soon they are planning to bring in their latest offering of NicaSil BB kit and other complimenting goodies along with it.. i am quite tempted to try those out based on my good experience with them. What i have learned so far with hot roding is, unless one has a fair idea and good backing of people how have a know how of how to make the kit function properly with the stock system, as an exercise it becomes quite labour intensive and a major headache to deal with!

So far like you i was lucky to get hold of people with the necessary know how ( after a long search!!) and they ensured that the final outcome would be to my satisfaction. Without losing the qualities of stock bike, i am able to enjoy the performance so atleast as per my experience with Motozone, it was plug and play (and pay for their hardwork) in a true sense. Till then i will keep on experimenting stage wise with the build.

Cheers,

Re: FE test update, 27th June, 2013

I guess like someone told me before, The Hotrodding scene in India is slowly taking off. Perhaps you can have something to benefit with your experience in what works, what doesn't and what is possible? There is nothing stopping you from going to Yamaha, Buying a spare cylinder, source a oversized piston, find a machine shop to bore the cylinder to your specs to suit the piston (make sure you already have the piston in your possession) and sell your own upgrade kit. Then with the proceeds from the sale of these pieces you can part fund your next mods. Just a thought. Its how a few mates back in Australia started out with their speed shops.

Re: FE test update, 27th June, 2013


Well mate, i am fine being the end user.. have no intentions of becoming the seller . Though i agree with what you said regarding hotter cam and power however, my requirements are very different from a hardcore drag enthusiast. better refinement and higher top end and here you have a happy customer.

Post all mods on my FZ i am currently eyeing the KTM 390 or if Bajaj is successful in bringing out a better quality rumoured 375 bike.

Cheers,

Re: FE test update, 27th June, 2013

It is GOOD to see such mature exchange of ideas,and datas in this thread.....I have learned much from @ Shiv 18 and Mad Mik's posts, and hope the trend continues and members like me will get the benefit of such shares....I must congratulate Shiv18 for a mature, balanced approach and views to the entire experience,Which I am sure will be an eye opener to all ...
Good Luck...

Re: FE test update, 27th June, 2013

Holy cow!!! I am missing all the action :-( ... need to meet these guys... Been meaning to meet up with Shv18 and the Motozone guys, but have been embroiled in work related things...

BB kit 3000 kms completion update, 4th July, 2013 Log

Hi all,

finally the kit has crossed the 3000 kms, another milestone achieved!! The ODO now reads 29,628 kms so she will be hitting 30 soon. I am still in double minds whether i should drain the Motul 300V engine oil in the next 1000 kms or try and see how long the oil lasts with the BB kit (The new oil is just 2,500 kms old since, the last oil change). The colour of the oil is still golden brown and it has not lost its sticky properties. On stock bike, i was able to run it safely till 5000 kms.

Anyways, i decided to celebrate this occasion by digging into one of my favourite and famous meat lovers street joints in South Mumbai, near Bhatia Hospital, Grant Road: Izzys Kebab Kona. Would highly recommend any Mumbaikar looking out for cheap, hygienic, awesome Chicken, Mutton Rolls and a complete meat feast. A really nice place to hang out :



FB Page: https://www.facebook.com/IzZysKebabKona?fref=ts

After Munching on a sumptuous 'Chicken Pocket, Chicken Rolls' and finishing it off with an apple pie, i am happy to announce that FZ - X's engine has been running real smooth. The 15T at times makes it difficult for me to register 65 kmph at 4200 - 4500 rpm and then 71 - 73 kmph @5000 rpm. The engine has become really relaxed and i am able to happily cruise @100+ kmph with the revs doing under 7000 rpm without crouching or literally putting any effort from my end! So far being within the city premises i have refrained from pushing her really hard keeping in mind the safety of self and public on the streets. i personally donot like street racing and i am totally against it under any circumstances.

The Leo Vince Exhaust with DB Killer on has upto some extent been able to keep me out of harms way. If i keep the engine rpms under 5000 then i have managed to shave off posers and crazy pulsar riders off my back when i am on the streets. But if i ever push her at 6000 rpms and above, for some reason these idiots go crazy and would try and swerve their bikes dangerously close to mine to have a race with them. I have no idea why but loud noise somehow triggers the idiot side of the brains of such riders to go crazy on streets. So in order to annoy them, i simply hit the left lane and reduce the speed to 40 kmph no matter how much honking and abrupt braking they do to instigate me, i keep her at those speeds only.. after 1-2 mins they get bored and move on... So one thing is for certain, roads are filled with idiots! But that doesn't mean you have to speak their language to get them off your back. Do exactly the opposite what they want and then they get irritated and move on challenging someone else on the road!

I have faced reverse cranking once or twice but not as bad it was with the RC cam. This usually happens when i shut off the engine on a long traffic red light and then attempt to start her off when it is about to hit green. After one reverse crank, she would then start normally without any fuss. I hope the decomp unit is doing its job properly! Thanks to Motozone, Pune i am having a ball of time. The racing CDI has not given up on me even with incessant rains playing a havoc on the roads of Mumbai. The setting no. 5 has played out to be the best ignition map for my ride.

FE has been hovering around 43-44 kmpl regardless of me at times getting carried away and revving her nuts off. With spirited riding, this FE figure is quite unexpected and is complementing my ride and the wallet too!

I am now impatiently waiting for the Yoshimura exhaust test and the 14T stock sprocket revertal to see whether my FZ - X remains docile & tamed or goes crazy on the speedo.


'

Mate you are missing a lot of action here.. Get free from your work, try out my ride and give your own individual perspective on the same. I am eagerly waiting for the NikaSil bores to arrive and will test them to destruction!!



Cheers,

Yoshimura FFE system, 14T sprocket test and the untold story, 9th July, 2013 Log

Hi all,

This may be a long one, so please do grab a huge mug of coffee/tea or your favourite poison of the day!!

after a wonderful stint with the Leo Vince GP Corsa Carbon exhaust system and enjoying the new found pleasures of riding my FZ - X with 15T front sprocket mod, i decided it was time to conduct the next line of tests. So many thanks to the guys at Motozone as they hooked me up with a brand new Yoshimura Full Exhaust system, Made OEM in Japan specially for Yamaha FZ. The objective was to see the changes i witness with a different exhaust systems and sprocketing mods effect on the overall character of my bike.



Pic 1: Yoshimura Full Exhaust system getting installed on my FZ - X.



Pic 2: Final installation of the Yoshimura Full exhaust system.

For further testing, they also installed the MSD Ignition cable in place of the stock one. Apparently the MSD ignition cable provides bigger and better ignition sparks compared to the stock one. MSD Official web link: http://www.msdignition.com/



Pic 3: MSD Ignition cable installed.



Pic 4: Stock Ignition cable of my Yamaha FZ - X

Now if all Noobs and early followers of this thread may recollect, so far i have tried:

* RC FFE with the stock bike configuration, no jetting on stock BS 26 carburettor as recommended to me by RC.
* Stock exhaust system with the FZ -X transformation: with RC camshaft and 120 mainjet, 17.5 pilot jet and needle jet stock on Pulsar 180 29 mm CV carburettor
* Leo Vince GP Corsa Exhaust, 15T front sprocket mod, stock cam, Motozone race programmed CDI, 122.5 mainjet, 17.5 pilot and needle jet stock on Pulsar 180 29 mm CV carburettor.
* Yoshimura exhaust system, 14 front sprocket, stock cam, Motozone race programmed CDI, 122.5 mainjet, stock pilot and mainjet on Pulsar 180 29 mm Cv Carburettor.

(P.S. : From hereon before reading the log below, I would request all readers to look at the ownership experience and other write ups with each of these performance parts as objectively possible without an emotional outburst on this thread or consider my posts as a deliberate attempt to harm someone's credibility as the tone may be a bit disturbing, too direct, may be considered harsh by readers. As i have mentioned before, all the ownership experience posted on this thread are as per my experience only. Other riders may have had a different experience with the kit and the sellers from the respective places. If it is not too much to ask, i would request the moderators to kindly help me keep the discussions on this thread objective and clean as the responses from hence forth may be deemed as whistle blowing and inflammable. Lets keep this thread healthy, clean and informative. Productive discussions are always a welcome on this thread.)

For the benefit of the readers, I will try and post my experience with each of them as briefly as possible:

1) RC FFE, Stock bike and no jetting on BS 26 Carburettor: I had ordered my exhaust from RC after getting very positive reviews from xbhp and owners here in Mumbai who raved about its lightness compared to stock exhaust, overall power bump, rev happy engine and the increase in FE compared to the stock form. I have already mentioned about my experience on the Yamaha FZ ownership thread in detail regarding the same. Anyways, after interacting with the seller many times including personally meeting him at his earlier workshop in blore, i placed my order for the same. After an endless trail of mails, phone & smses, for inexplicable reasons, it took RC 6 months to finally deliver the product ordered (many other riders who have ordered parts from there will agree with me on the same regarding the IST: Indian Stretchable Time format followed by RC when it comes to delivery of kits). I had already confirmed with the seller about jetting requirements for the same to which the seller had assured me that it was a simple bolt on "Plug & Play" exhaust system and no jetting was required. So i followed the instructions to the T and started my stint with the system.

EXPERIENCE: The exhaust i had received was a Gen 2 version from RC. The performance was immediately noticeable on my bike with the rpms going crazy and the speed of the stock bike increasing to 105 - 110 kmph without any trouble. I was experiencing highest FEs i had ever achieved in comparison to the stock exhaust, so yes the overall experience was really good and deemed worthy. The power was evident without the DB killer right from very low rpms and a huge increase in grunt of my ride.

However, the moment i had crossed 5,000 kms there were some anomalies discovered with the kit. Being of mild steel make, the exhaust would start rusting in a matter of 2 - 3 months and then after the monsoon season the rust formation increased. The FE post 8000 kms started slowly dwindling to the lower side which meant that something was wrong. I had then taken off the exhaust for re - plating and then found the end can devoid of any glasswool. For some reason the seller forgot to mention these things to me. After that due to work pressure, i was out of station for almost a good 7 - 8 months which didn't allow me to use the exhaust system nor my bike at all. Luckily thanks to the ever helpful guys from xbhp, i was able to figure out the possibility of rust issues with mild steel items with proximity to sea and the glasswool diminishing in this exhaust system and sort them out quickly. For all riders who have the mild steel version of RC exhaust, the rust issue may not be existent if one is far away from the coastal areas.

Later part with the onset of news of the stainless steel exhaust to be launched by RC made me change my mind about retaining the exhaust and then as posted on this thread, i sold it off to a rider who wanted the FFE for his ride, ensuring everything was sorted out (re-plating & glasswool re-fill) and my ownership experience pointers to the best of my knowledge with the kit. However, looking at the plight of riders still waiting for the RC exhaust i finally decided it was better to check out the well known exhaust manufacturers in the market and see what is what.

The performance no doubt was really good with the RC exhaust and for any average rider on the top: the speed gain, engine revving fast and FE is always a bargain for the amount paid. All this sounded great till i opened my engine for the kit installation and found that my ride was actually running extremely lean. So unlike the seller had claimed, my ride's carburettor needed re-jetting and in the long run was actually proving to be damaging to my ride. Rider abhimanyu31 was always skeptical with the claims made, however believing the seller i chose not to heed to his warnings and later understood the after effects of it when i saw what the engine head readings were showing. The detail logs have already been shared with you all in the earlier pages of this thread along with build pics. What i fail to understand is why such a huge delay with the delivery of kits? Why wasn't i informed about the things to keep in mind like possible rust formations, regular periodic glasswool refilling? why the need for rejetting was underplayed?? I will let the readers decide the plausible reasons by themselves.

I would still maintain that this exhaust does what it promises but with certain essential details not being shared with the end user which makes the overall ownership experience questionable! I wonder how many riders are still using this FFE without proper tuning/re-jetting.

2) Stock exhaust system with the FZ -X transformation: with RC camshaft and later with 120 mainjet, 17.5 pilot jet and needle jet stock on Pulsar 180 29 mm CV carburettor and the story untold! : I will not go too much into the details regarding this as in the earlier posts, i have already blabbered too much about it . As for the damaged carburettor, i had requested the seller to refund me the amount paid for the same and i shall ship him back the damaged carburettor after i have received the amount. With countless mails exchanged, phone calls unanswered or receiving "I am busy, racing etc." smses, till date the refund money has not been paid. So i am writing it off as a loss but making it a point to put this out in public for readers to decide what to make out of it.

Anyways, i got hold of a new carburettor and tried the jets sent to me by Joel as a first preset, the bike was behaving really bad. So i kept the base with 117.5 mainjet, 17.5 pilot jet and needle jet from stock Pulsar 180 29mm CV carburettor. At a later point i was informed by rider n-o-v-i-c-e that he was sent a carburettor with stock jets supplied with the 29 mm CV carburettor of Bajaj Pulsar 180 from RC, which was resulting in all the headaches the rider had faced and shared on this thread. So apparently the seller had not even bothered to check the kits he is selling before making it available to the end user.

Later as mentioned in my previous posts, the problems with RC camshaft and tuning grew to the point where after failed attempts to connect with RC for support, I decided to take matters into my own hands and finally got in touch with Motozone and the rest is history. As i went on writing my ownership experiences here and sharing with you all, I started receiving many distress PMs, mails and FB requests from owners who were facing tuning issues and BB kit blocks going kaput with no respite from the seller which made it certain that something was not right with the way things were dealt from the seller's end. For me it was impossible to believe that all of them were at fault when it came to the correct way of installing things and get the tuning set right!

After listening, trying to help such riders and now experiencing hot roding first hand: I do want raise a few queries for the Noobs and other senior riders to take into perspective:

* If the kit is "plug and play" and is more robust, "bullet proof" than stock as claimed, why so many kits are failing all across India? Why after plugging the kit so many riders are not witnessing an enjoyable "play" part of it?
* If the seller has gathered so much experience from racing why so many tuning issues, faulty or damaged parts are being sent to the end user?
* Why the pre-jetted carbs from the seller doesn't work and often result in lean tuning and later catastrophic failures of the kit?
* Why the owners have to wait for over 6 months to a year for the kits after they have paid the amount in full and everytime a new excuse is given for the delay?
* Why the riders were not informed about the after effects of using a hotter cam such as noise, vibrations etc. beforehand?
* Can we all in a general consensus consider this better than the "automotivepartsshop" experience faced by riders Madmik & Luckyluke ?

So anyways, here is the kicker: the day i landed up at Motozone's workshop, i saw a very familiar BB kit at the counter, looking similar to the RC BB kit. On further enquiry, i came to realise that these kits are simply imported from abroad and are not designed, manufactured nor tested by our seller here as claimed!! The difference lies in the fact that Motozone re-checks every bore for anomalies, re-bores it if neccessary, diamond polishes it and only then sells it to their respective customers with correct set of instructions, pre-tuned carbs with functional TPS and other goodies complimenting the set up. I have personally seen their tools and procedure to check each bore and with my experience and their honesty on the platter up for grabs i believe they deserve the rightful chance to sell such kits out in the market than the one i am writing against!

I know it is a bold statement to make! Now many of the riders may consider this as a serious allegation so for all those FZ riders who have installed the BB kit from our seller, i would request them to check the piston marking below and see if they have the same anomaly rider abhimanyu31 had pointed out on my kits piston in one of his earlier posts and ask themselves a plain and simple question: why the piston markings are incorrect if our "race engineer" had indigenously designed, got it manufactured and tested for whatever kms claimed? A well designed piston will not have such a silly mistake with the piston weight being on the wrong side.

So here is the second revelation: the piston actually comes from another bike, manufactured abroad which had the valve recesses marked in the correct way for that particular bike! Now since the valve layout is different on our stock FZ, the seller had just got the position of the valve recesses re-grooved to match to that of our respective bikes valve layout! So in short our seller is just performing the same thing what a local mechanic offers to do using may be a Pulsar 200 piston and re-boring the existing stock block for accomodating the piston but by using better marketing and selling tactics on the pretext of vast racing experience. get the picture??

Many times the BB kits sold by our seller will fail mostly because it has not been properly checked: whether the boring done was in the correct manner and then callously sent it across to the end user. So once the end user installs the kit, there is a constant struggle between the piston, piston rings and uneven sides of the wrongly bored cylinder and the engine oil: where the piston rings would want to fail having to deal with uneven sides of the cylinder, friction and rise in temperature but the engine oil with its lubricating and heat exchanging properties would not let such a thing happen. Eventually as one clocks miles on the kit, the force of friction wins and there you have an engine seizure with ring-land breakage and all other anomalies discovered. I am sure 90% of the rider who have had experienced kit failure have been blamed by the seller for wrong tuning, wrong way of run-in procedure and other nonsense. This is just one of the reasons behind the kit failure as far as i have understood and the list is endless! Does this mean that hot roding is bad? NO! i learned a lot from this experience and really grateful to the folks at Motozone for being honest and sharing their side hot roding the bike the correct way! So for all those readers who want to enjoy the fun-side of hot roding: my request, do your research properly, if you still feel that all that has been posted so far on this thread is a plain lie, interact with Motozone and then our seller: see which side offers you a plausible answer to your queries and then make a call which seller/tuner is better to deal with

If my hunch is right the only thing which is manufactured and truely designed by the seller is the exhaust and that's about it!

3) Leo Vince GP Corsa Exhaust, 15T front sprocket mod, stock cam, Motozone race programmed CDI, 122.5 mainjet, 17.5 pilot and needle jet stock on Pulsar 180 29 mm CV carburettor: After almost 500 kms of testing with the Leo Vince with and without the DB killer and the rest of the mods, i am happy to announce that this configuration is byfar the best that i have come across. Agreed with the Db killer on the overall performance is slightly limited but, besides the little hesitance between 4-5k rpm, i didnot witness any major reduction in performance nor on the fuel economy. 43-44 kmpl is a ridiculous FE for a highly modified ride. The Leo Vince Exhaust with Db killer has been extensively "Pandu" tested right from malad till south Mumbai, so far to the extent of riding right next to a beat marshal @ 5000 rpm and not for once the cop took a notice of my bike. At regular cops bandobast and licence and registration checking, not once i was asked a question about the Exhaust. So i am giving a green light to the LV exhaust with the Db killer as cop proof atleast in Mumbai!

Unfortunately due to the incessant rains i could never push her to the extreme limit and see what top speed i could achieve but the results were quite promising with my ride now able to achieve 60 kmph @ 4k rpm, 65 kmph @4.5k rpm, 70+ kmsph @ 5000 rpm and then 100+ kmph @7 k rpm without any effort from the rider!! If possible i shall attempt a GoPro video of the LV exhaust and a lazy speed run video with this set up if the rain gods finally let us riders here in Mumbai in peace!!

15T is an absolute fun with this set up..

4) Yoshimura exhaust system, 14 front sprocket, stock cam, Motozone race programmed CDI, 122.5 mainjet, stock pilot and mainjet on Pulsar 180 29 mm Cv Carburettor: Thanks to the incessant rains i have not been able to take my ride out to stretch her legs but the initial impression with the stock 14T sprocketing has been really disappointing! My ride now feels no longer relaxed as with 15T and needs to be at higher rpms to achieve the same speed. Ofcourse it is to be expected as one fiddles with the sprocketing the gearing of the bike will change. Being addicted to the 15T, i have decided not to carry on any further tests with this set up and will revert to 15T to give a final verdict of the exhaust and the ride's behaviour.

INITIAL IMPRESSIONS:

Now when Yoshi was installed, we had intentionally kept the carb tuning untouched in order to see whether with the new exhaust we need to change the fuelling or it will remain the same with the existing AFR config. The moment one fires up the FZ - X with Yoshi on, the power is evident! The bike immediately settles to a bassy note which sounds really sweet and awesome.

The Yoshimura exhaust looks absolutely beautiful with the fit and finish of a true Japanese craftsmanship If i may be bold enough to claim, this is byfar the best exhaust i have come across and is miles ahead of the build quality than the earlier two i had tested. Even the welding joints have been done so beautifully. This exhaust is a really a looker. One cannot stop himself from having a look and admire the beauty of the exhaust.

The performance is a step ahead of Leo Vince and the best part is that unlike RC FFE, the backfiring noise is more or less non-existent. The bike will easily hit red-line without any trouble. This may sound like a rock concert explanation but if RC FFE is pure noise, Leo Vince is a mix of bass and treble and Yoshi is pure Bass and less treble when it comes to the noise it makes. If i may, performance wise i would consider it far more superior than Leo Vince and even RC FFE! With the tuning left untouched, i was at times experiencing engine shutting off when riding in bumper to bumper traffic and at times a slight sound engine knocking at some rpms which i guess more or less is a clear indicator of fuelling not being in the correct setting required for this exhaust. I think shifting to pilot jet 20 size from the 17.5 and making the fuelling rich by adjusting the AFR screw (as suggested by PSR Ji) should be able to get rid of this problem.

As i continue clocking more miles with this exhaust i will give out my final verdict on the same. This exhaust doesnot come with a DB killer. So far i haven't had any issues with our pandus in the city but it is still to early to give out a conclusion!



Pic 5: GoPro Hero camera courtesy abhimanyu31

Many thanks to abhimanyu31 for lending me his GoPro camera. Will conduct amateur speed runs when the weather and time permits..

I now understand why senior riders like PSR Ji, Aargee and many others were so skeptical against the seller mentioned on this post. I guess the intent was right but somewhere the productive discussions took an ugly form of mud slinging and hate threads or people coming up with selling their own kits etc. as many others joined in either being pro or anti seller in other threads.

I am sure a lot of riders do have this question in their mind: am i now a new benefactor from Motozone? taking my cut for advertising their brillance? The answer is a plain NO! I am not gaining anything except getting things done the right way and now being finally content with my ride!! I personally feel the money spent on getting the kits from the seller was a wasteful exercise, had i known about these gentlemen earlier selling the same kits but with better support system in place and QC parts sold to the end user, i would have never taken the name of RC on this thread nor anywhere. I am just trying to share the good side of hot roding that i have experienced hoping others will get benefitted from it and not taken for a ride ever again! It was indeed a learning experience for me about how an engine functions and how minute things can upset the functioning leading to a potential disaster.

Anyways enough of this "revelation" exercise! Lets get back to the report log session shall we? i will try and quickly get hold of the amateur speed runs video live on the net as soon as the weather clears out.

So stay tuned for more reports..

Cheers,

Yoshimura FFE system, 14T sprocket test AFR Issues, 11th July, 2013 Log

Hi,

thanks to the incessant rains here in Mumbai, i have not been able to go for the GoPro amateur speed runs video making session at all. Anyways, i have covered around 200 kms with the exhaust so far and just as i had suspected the fuelling is currently not right. I am witnessing engine shutting of at times and the idle rpm being very mildly jumpy.

As mentioned earlier, next time i meet the guys at Motozone, we shall be trying out 20 sized pilot jet i had procured earlier from TVS spares shop and make the fuelling slightly richer. As per the suggestion from PSR Ji, i will also check the head metal gasket of my FZ - X if for any reason we need to file it slightly as it may be one of the reasons behind slight knocking sounds i am witnessing now besides fuelling. Though when we did the build the metal gasket was found as per the sized of the bore. But still let me re-check and get back to you guys.


I managed to get hold of a screen grab of Dyno runs from the official company website of both Leo and Yoshi:

Personally to me, Yoshimura FFE is no doubt one of the best exhaust i have come across. Its build quality and performance is leagues ahead of the other two. However, after 200 kms of runs, i can certainly confirm one thing: It is really loud!! Official data sheet from Yoshimura puts it at 93 decibel @3750 rpms so you guys do the math. But in comparison to RC FFE i would still rate it gentle if that can be considered a correct word in terms of the overall sound produced. Performance wise it beats the pants off the other two without any question. However, now with the noise restrictions strictly being enforced especially in Mumbai, it will get one into trouble sooner or later. As per my experience, especially for a tourer, it is not a good thing to ride with such an exhaust for long distance, as the loud noise will induce fatigue and in the long run may result in hearing loss. The cops so far have been kind in Mumbai, but i don't think they will be for long, if they decide one fine day to be on the lookout in order to make some greens . So if you are one of those riders who enjoy loud pipes and don't have issues with local cops then out of the 3 , performance and build quality wise, this is the best exhaust one can currently buy in the market.

If one is still keen on getting this beautiful exhaust, you can connect with Motozone. They also have the Carbon tipped Yoshimura FFE up for grabs.

But keeping the ground reality in check: out of all the three exhausts that i have tried so far, Leo Vince GP Corsa carbon FFE is a better bet as with the DB killer the sound is muffled pretty good without losing too much on performance. i would recommend the Leo Vince GP Corsa FFE out of the three as it has a balance of everything and with the DB killer, the noise is not so intrusive nor disturbing the rider at all. Best thing is it doesnot cost a moon, only priced slightly higher than RC stainless FFE. Cops never bothered me with this exhaust.

Now based on the tests done on all these exhausts, i gave a suggestion to Motozone guys to attempt designing and manufacturing an SS grade stock replica FFE with the end can packed with noise insulation material. So stock bike owners as well as souped up riders can enjoy their ride without the fear of getting caught and then fined by cops as the end can will be hidden inside the plastic contraption like our stock mid ship muffler has. Though agreed, one cannot expect the full performance gain of a race spec'd exhaust, this one will nonetheless provide you the speed, bump in performance and overall a better outflow of gases thus helping one to release a few ponies from their respective rides. Rider Iceman331 has already done such a mod with his ride and it is functioning quite well. This exhaust will be coated with black heat resistant paint so even if one is stopped by cops they cannot distinguish between the stock exhaust and the hidden FFE plonked into your respective bike. This one will be properly tested and designed for better efficiency and pulse tuning, not a simple a pipe cut out from a lathe shop and then sold to the customer like the local loud pipes, if you know what i am saying!!

Motozone has agreed to start working on it rightaway with the end can to be packed with industry standard heat resistant ceramic glass wool which will negate the need to refill the end can after every few thousand kms unlike it was the case with gen 2 RC FFE. And after extensive tests, will also provide a set of instructions along with the FFE so that riders are well aware of what needs to be done in terms of re-tuning or rejetting, if needed. The good thing is they will provide everything from their end so that the rider has a proper set of instructions, the FFE and a set of jets to get it tuned locally if required. Thus. hopefully the riders will finally have a "Plug & Play" FFE in a true sense, available in the market. As per my discussion with them, the pricing will be pretty much under the grasp of Indian riders. The first one shall be tried out by yours truely!! Later when the Dyno is available, i shall get a few runs done on it

This an (Horrible!!) artist representation of what the stock replica FFE with heat resistant matt black coating might look like:


Pic 3: My photoshopped version of stock replica FFE. The end can will have the mounting points for the plastic contraption to bolt on. The exhaust end pipe diameter will be bigger than the stock one. Stainless Steel 304 grade.



Thank you sir for your kind words. I hope all the riders don't get spooked with hot roding. Just because certain firm has not been honest doesnot necessarily mean that all are bad. The important part is to understand what works and what doesn't. Correct process of installation is a must along with the QC (quality checked) parts. at a later point of time for the benefit of the community i shall provide the torque ranges required in detail for the Noobs & others for all the essential internal parts of the FZ.


Well the attempt is always to share my experience in detail. I hope a lot of people are getting benefitted from it. that's all I hope readers and every person looking for help especially with FZ power up kits will read this properly and understand the process, the repurcussions and the benefits too with hot roding their respective FZ/Fazer.

Thank you for your kind words but i am a mere enthusiast learning things on the way and documenting everything on this thread. Well the attempt from my end is always to provide data along with a write up to make it more plausible and easy for the readers to comprehend. I am waiting for India's first official privately owned motorcycle Dyno (by Dynojet USA: Dynojet Motorcycle Dynamometer ) to be launched in Pune which will be available to the public wanting to go for a run, ofcourse for a certain fee and will provide the data which will finally put to rest the actual power produced by a souped up ride compared to stock. And unlike stupid claims made that a dyno may give out wrong readings etc. for the first few weeks the technicians from USA will be present and will be doing the runs under their watch. So i shall bribe rider abhimanyu31 to tag along with me and get the runs done.

For all the noobs who have no idea what is dynamometer/Dyno, here is a video link:



In layman terms: it is basically a lie detector which gives out the true bhp and torque readings reaching the rear tire, thus the actual power available to the user. It is a globally accepted platform to get the tuning set right for riders looking for more power or have done performance modifications done on their respective rides.

So now it is all about wait and watch and hope the set up comes quickly to India.

BTW Yoshi looks really awesome!!

I hope after the revelations on this thread no more praying happens ever again! No more victims




Cheers,

Shv 18 , for the first time I am seeing dyno figures HERE, from the "manufacturer". How easy and believable it is to understand the claims Vs actual figures.....I hope your honest attempt to communicate the real time dyno charts does not get watered down by claims that, actual Dyno isn't everything, and a "Seat of Pants Dyno" is more accurate..
Good Luck...
