Re: Motozone Headwork & Cam: Aborted Speed run 20th Aug, 2013

That would really seal the deal!

and "Tailor Saab" had me in splits!
I doubt people not aware of the "promotional literature" would get it!

Re: Motozone Headwork & Cam: Aborted Speed run 20th Aug, 2013

I would have loved to..believe me, i have been aching to do one since, the last 2 months but as discussed, i am not comfortable with taking such a risk. On highways with higher speeds, the tendency of the engine consuming more oil with such a leaky bore is way higher than on streets. I really appreciate the offer but just that this constant headache and worry at the back of my mind will not allow me to enjoy my ride at all. I hope you understand my situation.

Well the credit for the term "talior saab" goes to none other than rider jonahmano.

I guess then we have no other option but to ride to Colaba. It is no less than a weekend ride for me, with streets comparatively empty. Love the weekend atmosphere of South Mumbai. One of the reason to come down is Bade Miyan..

Re: Motozone Headwork & Cam: Aborted Speed run 20th Aug, 2013

Well Sunday it is then...

Engine Oil Myth??

Hi All,

just came across this interesting video explaining myths about engine oil:

Busting Oil Change Myth - YouTube



I am just wondering whether using Shell Rimula R4 will solve the problem of oil seeping in through the rings?? :



Regular Oil vs Synthetic Oil -EricTheCarGuy - YouTube


I hope riders can contribute something more to this topic.

Re: Engine Oil Myth??

Let's connect on phone on Sunday in the morning half. We can then coordinate the timings and I am sure Motozone will be willing do the stock coolant replacement with Engine Ice. They have already done the same on KTM 990s, R1s and Ninja 250Rs which have a reputation of grilling your legs at stop and go traffic.

A humble suggestion to [MENTION=32641]shv18[/MENTION] and [MENTION=35854]chinmayakar[/MENTION] This thread is one of the best on xBhp currently where a lot of knowledge and information is being shared. So please delete the posts of personal plans, as it just doesn't gel wit the rest

I say this as a member who is learning a lot from this thread and not as a moderator!

Re: Engine Oil Myth??

Hehe.. suggestion taken into consideration, shall refrain from posting personal conversation on the thread. I am glad that there is a keen interest on whatever little i am able to share on this thread with the help from a lot of riders in india and from abroad as well.

Motozone Kits : Ported Head & High Lift Cam: 350 kms Test Report, 21th Aug, 2013

Hi All,

Yes i am crazy to clock 350 kms quickly since the installation of the kits.

Though thanks to the leaking bore, i have no choice but to keep the high speed runs at bay. I am keeping my FZ - X hovering at a maximum band of 75-80 kmph on highways, even on an open road and on streets well, keeping things sober. No hard accelerations nothing.

So anyways, here is a quick review based on the parameters mentioned earlier:

What's Hot:

* Performance Gains: Today i got the Carburettor lever issue sorted out and also did some more plug chop tests to verify whether spark plug readings we got the last time remain the same or not.



Pic 1: Plug Chop Test: Chocolate brown tan indicating a Stoich AFR.



Pic 2: Updated image of the spark plug post Plug Chop test.

Forgive me for the horrible pic quality but i guess my photography skills with the phone cam are very limited. There is a major increase in performance compared to stock. The bike now just wants to lunge forward the moment a slight throttle over 1/4th is applied. I guess all the credit goes to the High Lift cam now. Let me put it this way: i have better performance compared to RC cam minus all the headaches. So "Tailor Saab" can see my bike's backside, i am never going back to that wild cam nor to the cheap kits ever again!!

* Acceleration Gains: Well the last time the images shared from the aborted run speak for itself. The bike now loves to accelerate fast and the nos. on the speedo climb very quickly. Readers please remember that the last time i had attempted the speed run, it was with the DB Killer on. The speed of 94 kmph was achieved in under 200-300 mtrs which in my books is pretty fast. And don't forget the same acceleration nos. have been achieved with a 15T front sprocket mod and with a "feather weight" who has no experience with drag racing. I have a feeling that even with the custom sprocket set up, we should be able to achieve atleast quick figures of 12 seconds or under for 0 - 100 kmph acceleration tests with the G Tech RR Pro GPS Data logger. But until we do the test... let me hold onto my horses.

After i got the carburettor sorted out, today on 1st gear she was able to hit 56 kmph and on 2nd i was already crossing 69 kmph really fast.....but then i decided not to be stupid as it is not worth pushing the leaking bore too much! I hope the rest you guys can figure out by yourselves

* Low speed performance: This turned out to be the most surprising part for me. With a high lift cam, i was expecting the low end torque and the acceleration with a higher gear to be much worse compared to a stock bike. RC Cam is pretty horrible when it comes to low end performance on higher gears under 2 - 3k rpm. My bike now is easily able to pull up @5th gear on speeds as low as 27 kmph without any lugging or knocking. However, that being said with a 15T compared to stock set up the bike does start lugging if you reduce the speeds too low. Not that i ever go crazy low on speeds or prefer riding on higher gears.. as a test it does show the potential gains with the headwork and the high lift cam working in unison. As long as the revs are above 1800 rpm the bike functions just fine!! Motozone kits get full marks in this regard.

* Top end Acceleration: Unfortunately this is one part i am yet to test out. Today while on my way back home the clutch return spring broke!! So i will have to pay a visit at the Yamaha SVC tomorrow and get it replaced. To be honest the stock clutch return spring is stock OEM since, the last 30k kms and almost 3 years old. not bad for a cheap part surviving the corrosive coastal wind for so long. If the conditions are favourable i shall attempt a speed run, may be not all the way to top keeping in mind the leaking bore but anything above 115 kmph with the engine raring to go more is more than enough for me to give a green nod to this head work. But until then, let's not get carried away shall we??

* Average life of the kits, reliability and operation efficiency under high speed runs on highway: NA.. still have to clock more miles....

* GTech GPS Data to prove "i practice what i preach!" and have the necessary information to prove it: NA.. Yet to attempt.

* Dyno runs: when they become available to provide irrefutable proof that the BHP gains at the wheel are verified by a certified Dyno techinician unlike our Tooner: Still waiting for the Dyno!!..... NA


What's Not:

* Losses in comparison to stock: As mentioned earlier, the engine when cold, the rpms are slightly erratic. One has to slightly rev the bike like the old worn out bikes we see in traffic where they constantly have to rev slightly to keep the engine from shutting off. This exercise has to be carried on for the first 5 - 10 mins. After that she purrs at a steady 1600 - 1800 rpms and the engine doesn't shut off unknowingly like it used to happen with the RC cam. At times, if one does switches off the bike on a traffic signal and then wants to move ahead as the lights turn green, one will have to apply a slight dab of throttle to bring her to life. Thanks to the nature of the high lift camshaft, the engine braking is drastically reduced. So one will have to change the riding habits and will have to apply engine braking and the conventional braking system together a bit more to reduce the speeds quickly.

Besides that i have not seen any other major issues with riding my bike in comparison to stock. Still to early to give a long term review but nonetheless the initial vibes i am getting from these kits so far are really good!!

* Undue vibrations if any: None!! This cam is working beautifully with the rest of the machinery. No undue vibrations even at high rpms when compared to stock and let's not talk about RC at all in this department. The RC wild cam sucks and is far behind this Motozone cam. No reverse crank, no major piston slap occurrence since, the last 350 kms.

UPDATE: I have put a comparo video link between the amount of noise emitted from the engine bay by Motozone highlift cam when compared to "Tailor Saab": http://www.xbhp.com/talkies/general-...e-fz18-50.html . I hope this should give all the Noobs and the readers a fair amount of idea regarding what me and all others have been complaining about so far besides the other major issues.


* Streetability compared to a "Tooner's special Race spec'd bike for streets" which blows up in 500 kms!! : In a true sense, this is a proper street set up now.. Minus the crappy BB kit! The camshaft doesn't lug the engine or induce crazy vibration in the name of performance!! there is no weird stitching noise from the engine bay and i am sure the valve train system is also happy not getting slapped by the cam lobes like it was the case with the wild RC cam! Please note that unlike the stupid wild cam, i still have the Decompression unit installed and the valve clearances are pretty much close to stock.. so the valve springs are not getting compressed like in the case of 0.06 mm inlet and 0.08mm exhaust valve clearances recommended by the tooner which BTW doesnot reduce the stitching noise. Rider n-o-v-i-c-e can verify my claims for the same as his set up doesn't have the decomp unit and the the valve clearances are as per the recommended settings by the "Tooner". I guess with the decomp unit being still functional, my stock starter clutch and the starter motor are safe now and will have a longer life compared to other riders still running on the kits from the latter.

I also don't have an irritating red light constantly glowing on the display console as i have a fully functional TPS which i guess is also adding to the smoothness and the refinement of the engine. In this case i will call Motozone kit experience "As close as stock". However, till significant no. of kms are done with a new NiKaSil bore and the ported head and the cam, It is still too early to give complete brownie points in the reliability department yet.

* Loss in FE, Range for the pursuit of power and performance: Ok for mileage hungry junta! I had filled 5.81 ltrs and so far my ride done about 203 kms with the 2 bars still showing on the fuel meter. This run also includes all the fun high speed short burst test slots alloted to riders FZERIDER, chinmayakar, mine and Mr. Vikram's as well (With DB insert & W/O DB Insert) while we were testing the gains over the earlier head with the stock cam last Sunday. It also includes the attempted and aborted speed runs and generic highway runs.

I had refilled the tank afterwards before she could hit reserve. But on an average, i think a conservative figure; FE range of 35 - 38 kmpl is what i am getting on my ride right now. I shall do one more round of FE test to confirm the nos. but if this is true.. i really don't know what Motozone meant by loss in FE with this version of ported head and the highlift cam?? Am i supposed to expect more on "splendor mode"??

* Any other parameters: NA

Readers, please note that this is only a quick 350 kms ride report. But i guess the initial impressions look really positive. All major gains minus none of the drawbacks like i had with the "Tooner's" kits.

@psr: Sir, may be this is too early but i guess Motozone guys know what they are talking about. The Gtech run with the NiKaSil bore should put all disputes to the rest i suppose?? i am really liking the first half of the quick ownership experience so far...


More reports coming soon... Let the good times roll...


Cheers,

Re: Motozone Kits : Ported Head & High Lift Cam: 350 kms Test Report, 21th Aug, 2013

Shiv 18,.... Good to see that the tuning and marriage of the new Cam is giving you a better acceleration, without the noise or jerks,or vibes....
All high lift Cams will result in fluctuating low RPM idle.....the wilder, the more the low end struggle..
I am Happy so far to see that Motozone is delivering what you were looking forward to ...and sincerely hope the experience continues and no Lemons are tossed in later..

Re: Motozone Kits : Ported Head & High Lift Cam: 350 kms Test Report, 21th Aug, 2013

Great!! You did 350 KMs so soon, and you are afraid to go on a ride thats hardly 120 KMs round trip with couple of breaks thrown in between
Glad to see performance gains on your FZ. When is the Nikasil bore expected? That should really take the performance to the next level.

Regarding the rpm fluctuation, I had experienced same on my stock FZ. The rpm during cold start would fluctuate for a minute or 2 and then stay steady. Never faced cold start issue because of that. It would always start with the first crank.

Re: Motozone Kits : Ported Head & High Lift Cam: 350 kms Test Report, 21th Aug, 2013


The question is not about 120 kms journey but rather the constant rpms and speeds at which one will have to ride the bike. Under those circumstances the chances of the leaking BB kit to consume engine oil is much higher. In the city limits i am keeping the speeds and rpms under check and also she is given a break after 30 - 40 kms. If and when i do go for the high speed runs, i diligently check the engine oil level and only then go ahead with such a task. So it is not hunky and dory thanks to this annoying leaking bore spoiling all the fun.

One correction on my part, it was not the clutch return spring but the clutch cable which went kaput! Unfortunately the SVC didn't have an FZ clutch cable in stock so i got hold of a Yamaha SZ-R clutch cable for the time being which is more or less a match with the FZ's one. The only difference, is that the SZ-R's clutch cable is slightly shorter in length but nonetheless they can be interchanged with FZ.

After clutch cable change the SVC head requested me if he can go for a short spin. Again, as a protocol, i ensured that the engine oil levels are ok and then agreed to let him take my FZ -X out.. After 5 mins he came back with a wide grin and was impressed with the silent highlift cam. According to his feedback, the gentlemen was able to hit 120 kmph on a short stretch and the way the power was building up was quite surprising for him.

I am now really anxious to take her out for a GoPro speed run just to see with my average drag capabilities, how much speed i can gain with the DB killer and without the DB Killer.

I have been annoying Motozone to finish building their first NiKaSil bore prototype and let me have go on it ASAP. Until then, i am stuck with this kit. As per my regular discussions with PSRJi we both feel that due to the superior nature of a NiKaSil bore the engine should be revving even faster and should be reliable if not as much a stock but atleast close to stock bike. But until the tests are completed let me hold onto my comments.

Amateur speed run with Leo Vince DB insert,Test Report, 22th Aug, 2013

Hi All,

i guess i couldn't contain myself and thus decided to go for a speed run and see what changes am i experiencing post the installation of the head and cam from Motozone.


All readers please keep these factors in Mind when the speed run was attempted:

* The rider has no drag skills whatsoever and is "Feather weight" (That means pretty erm heavy!!)
* The BB Kit is losing compression and eating away oil so the "tooner" kit is not making enough power.
* The Leo Vince exhaust with the DB insert was kept installed to simulate the street riding scenario
* Ambient temperature: 28'C
* The test area was devoid of any major traffic and no pedestrians were present.
* The test rider was completely geared up and also would request all the readers of this thread not to try this on streets. Be a responsible rider.
* The above test was done just to see the performance gains over stock
* Sprocket Config: 15T front and Rear 40T so the acceleration timings will take a hit compared to the stock sprocket set up.
* The shifting skills at right rpm of yours truly is erm.. horrible!!
* While performing the run i was constantly worried about the leaking BB kit.


The video link:
FZ/Byson Speed Run with Leo Vince GP Corsa exhaust and DB insert - YouTube


With the DB killer the power felt very restricted and the bike felt like struggling on WOT. My guess is with a fully functional and non-leaky bore without the DB insert, it should be able to easily knock off 2 - 3 seconds compared to this run with my average skills. I am honestly very bad when it comes to drag runs. I guess a seasoned rider will probably do justice to making these videos.

Just for comparo a stock Yamaha FZ 0 - 100 kmph acceleration video:

fz 16 0 100 by HTC II - YouTube


Next time, i shall attempt with the DB insert off and we will see if there is any major change with the way my FZ - X would gather speed.


Till then stay tuned.

Cheers,

Re: Amateur speed run with Leo Vince DB insert,Test Report, 22th Aug, 2013

When you decide to tear down the engine, can you do me a favor for my curiosity and more than likely yours and the viewers playing at home, can you carefully remove the piston rings and carefully insert them into the bore, Then measure the ring end gaps, The top, middle and bottom of the stroke too. Write these down and then compare between your new engines rings.

Also how did u run this engine in? If I recall it was careful careful?

----consecutive posts auto-merged-----

Took me a while to scroll back and find the writeup on your compression tests.
I have a couple questions.
The test was done on a cold engine or Hot?
this report was the results of your "dry" test? Did you squirt some oil into the cylinder then repeat the test? Regardless if the gauge was reading wrong, the numbers are just a reference point on the sweep of the needle.

The reason why I'm asking is. The dry test will be for the valve seats. Test the valves are sealing against the seats.
The wet test is to test the rings. the oil will help seal up any gaps in the rings, Providing a more complete seal for a few strokes needed to test the compression.
If you did the test wet (after the dry of course) you may notice the needle reading higher, then you can safely say its the rings, If the needle stays the same (pressure reading 98-99psi) then you can say its the valve seat/s.

Hot test will give different readings again but closer to engine operating temps, where the metal has expanded and closed up any small holes (piston ring end gaps for example) and create a better seal.

Just a couple things to think about next time you are running compression tests.
