Re: Firebrigade Bullet

Hi PSR sir, its exactly as you said. This injury changed my perception of life and work altogether.

You wont believe the bad luck. Only that day I skipped the goggles. Honestly I only went to review the progress of work and SMACK.
It went right through the eyelid and it was 'die hard' all over the floor. Hehe.

But now after a month it seems to have healed for the better. No more games with the eyes ever again in my life.

I am in touch with shv18 and Motozone and shall start work on the bike after sometime.

cheers...

Re: Firebrigade Bullet

Thats sad bro!! Get well soon and make sure you dont skip any safety equipment in future. It happens once in a while and you cant judge when its going to. Take care!! "Prevention is better than cure"

Re: Firebrigade Bullet

Here is a simple Explanation and method of Tuning a CV Carb....this text is an extract from a write up by Marc W. Salvisberg .....

Follow steps in order....First, dial in:

1. Top end (full throttle / 7.5k to redline -
Best Main Jet must be selected before starting step 2 (needle height)!

Select Best Main Jet
To get the best, most even top end power (full throttle/after 7500 rpm), select the main jet that produces the hardest pull at high rpm.
If the bike pulls harder at high rpm when cold and less hard when fully warmed up, the main jet is too large. Install a smaller main jet and retest
until you find the main jet that pulls the hardest at high rpm when fully warmed up. This must be done first - before moving on to the other tuning
ranges.

If the bike doesn't pull well at high rpm when cold and gets only slightly better when fully warmed up, the main jet is too small.
In order to properly tune the midrange and low rpm carburetion, THE MAIN JET MUST FIRST BE PROPERLY SELECTED after 10 to 15
minutes of hard use!

Do not pay too much attention to the low-end richness when you are changing main jets - you still need to be using the main jets that produce
the best power at high rpm. You will deal with the low-end / cruise later - after step 2.

2. Midrange (full throttle /5k-7k)

Step 1 (Best Main Jet) must be selected before starting step 2!
Select best needle clip position
To get the best power at full throttle / 5k-7k rpm, adjust the needle height, after you have already selected the best main jet.
If the engine pulls better or is smoother at full throttle/5k-7k in a full throttle roll-on starting at <3k when cool but soft and/or rough when at full
operating temperature, it is too rich in the midrange and the needle should be lowered.
If the engine pulls better when fully warmed up but still not great between 5k-7k, try raising the needle to richen 5k-7k.
If the engine pulls equally well between 5k-7k when cooler as compared to fully warmed up, the needle height is probably properly set.

Do not pay too much attention to the low-end richness when you are changing needle clip positions - you still need to be using the clip position
that produces the best full throttle / 5k-7k power in conjunction with the main jets (Step 1) that produce the best power at high rpm. You will deal
with the low-end / cruise next.

3. Low end (full throttle / 2k-3k)

Step 1 (Best Main Jet) and Step 2 (needle height) must be selected before starting step 3!
Float height (AKA fuel level & how to..)
To get best low-end power, set float height (fuel level) so that the engine will accept full throttle, without missing or stumbling, in 2nd gear from

2.5k to 3k rpm at minimum.
Float heights, unless otherwise specified in the installation guide, are measured from the "gasket surface" of the carb body to the highest part
of the top of the float - with the float tang touching but not compressing the float valve spring.
If the engine has a "wet" rhythmic, soggy area at full throttle / 3k-4k rpm, that gets worse as the engine heats up, lower the fuel level by
resetting the float height 1mm greater (if the original was 13mm - go to 14mm). This will lower the fuel level, making full throttle / 2k-3k rpm
leaner.
If the engine is "dry" and flat between 2k to 3k rpm, raise the fuel level.
Example: change float height from 15mm to 14mm to richen up that area.

REMEMBER, since the main jet WILL affect low speed operation, the MAIN JET has to be within 1 or 2 sizes of correct before final float
setting.

Warning: If the engine is left with the fuel level too high,, the engine may foul plugs on the street and will be "soft" and boggy at part throttle
operation. Adjust Floats to raise/ lower the Fuel Level.
Base settings are usually given if a particular application has a history of fuel level criticalness. The Fuel level height in the float bowl affects full
throttle/low rpm and, also, richness or leanness at cruise/low rpm.
Reference: a bike that runs cleanly at small throttle openings when cold, but starts to show signs of richness as it heats up to full operating
temperature, will usually be leaned out enough to be correct if the fuel level is LOWERED 1mm.

Needless to say, FUEL LEVEL IS EXTREMELY IMPORTANT!!!
If there are low-end richness problems, even after lowering the fuel level much more than 1.5mm from our initial settings, check for needle wear
and needle jet (part of the emulsion tube). See Worn Needle and Worn Needle Jet diagram. It is VERY common for the brass needle jets (in
the top of the "emulsion tube") in 36mm, 38mm and 40mm Mikuni CV carbs to wear out in as little as 5,000 miles. Check them for "oblong"
wear - the needle jet orifice starts out round! Factory Pro produces stock replacement needle jets / emulsion tubes for 36mm and 38mm

@PSR Sir.. [MENTION=32641]shv18[/MENTION].. "A man's mistakes are his portals of discovery." Let them learn from their mistakes

@ All the other people dreaming to get Joeled.. All the very best And do remember "What do you first do when you learn to swim? You make mistakes, do you not? And what happens? You make other mistakes, and when you have made all the mistakes you possibly can without drowning - and some of them many times over - what do you find? That you can swim? Well - life is just the same as learning to swim! Do not be afraid of making mistakes, for there is no other way of learning how to live! "

Re: The POWERHOUSE Fz18

Psr sir, the same jetting method can be used for cable slide carburetors as well. Right?

Sent from my GT-I9001 using xBhp Connect mobile app

Re: The POWERHOUSE Fz18

People who want to commit mistakes and learn are free to do so.... I guess, what Shv18 is trying hard to explain here is that the process of Hot rodding is not so easy as "Plug and Play", and his experience with a specific supplier of parts....
As true bikers we are here to share knowledge and try to help each other as possible,....but ultimately it is the individual's choice..
We all live and go through life's experience by the choice we make...
Yes it is almost the same...why almost ? because the direct actuated throttle slide rises in tune with the accelerator , and not by vacuum...this makes it difficult to tune the carburetor properly to give as best a performance as the CV...The Right wrist twist practically controls the acceleration ,and too much of it will raise the slide a lot and make the AFR lean...and if you upjet to compensate for this, then at normal acceleration the AFR will be very rich.....so tuning a non-CV carb is tough than a CV...
But for normal riding the methods are same

Continuing from last post on Carb tuning..............................


4. Idle and low rpm cruise
Fuel Screw setting (AKA mixture screws)
There is usually a machined brass or aluminum cap over the fuel screws on all but newer Honda. It's about the diameter of a pencil. Cap
removal details. Newer Honda carbs have no caps, but use a special "D" shaped driver, usually supplied in the carb recal kit.
Set for smoothest idle and 2nd gear, 4k rpm, steady state cruise operation. Set mixture screws at recommended settings, as a starting point.

For smoothest idle, 2nd gear 4000 rpm steady state cruise , and 1/8 throttle high rpm operation. (pj tuning information)
Pilot fuel mixture screw settings, float level (but, you've "fixed" the fuel level in Step 3 - which you have already done!) AND pilot jet size are the
primary sources of mixture delivery during 4000 rpm steady state cruise operation.
If lean surging is encountered, richen mixture screws (turn out) in 1/2 turn increments. Alternative pilot jets are supplied when normally required.

Pilot fuel mixture screw settings, float level and pilot jet size also affect high-rpm, 0 to 1/8 throttle maneuvers. Too lean, will cause surging
problems when the engine is operated at high rpm at small throttle openings! Opening the mixture screws and/or increasing pilot jet size will
usually cure the problem.

NOTE: A rich problem gets worse as the engine heats up.
If the throttle is lightly "blipped" at idle, and the rpm drops below the set idle speed, then rises up to the set idle speed, the low speed

mixture screws are probably set too rich: try 1/2 turn in, to lean the idle mixture.

NOTE: A lean problem gets better as the engine heats up.
If the throttle is lightly "blipped" at idle, and the rpm "hangs up" before dropping to the set idle speed, and there are no intake leaks

and the idle speed is set at less than 1000 rpm, the mixture screws are probably too lean: try 1/2 turn out, to richen mixture. Be sure there are
no intake leaks and the idle speed is set at less than 1000 rpm!

FZ - X Motozone tests for speed runs

Hi All

I am still out of station.. so please do bear with me if my posts on this thread come slightly late. I have been recently updated by Mr. Vikram about the latest happenings with my bike. With a lighter rider, the first test run with just slight tweaking of the existing BS 29 carburettor's AFR yielded a top speed of 130 kmph (Speedo indicated) with the LV exhaust DB killer still installed. I would like to add a 5% speedo error.. so the true speed will be around 123.5 kmph.

Mind you readers, this is just round one with messing around with the carb settings, jetting experiments etc. We are yet to try out different types of carbs. I have a feeling we should be able to reach the territory of KTM Duke 200's top speed or may be slightly higher with some more work done on the carb (atleast on the speedo!!) . However, let me not jump the gun until the tests are complete. I believe Gtech GPS data logger runs will give all of us a better idea about the potential of the existing set up.

Does this mean i can beat the pants off a Duke? I would say NO!! A KTM FI engine is far more superior and has a better thermal efficiency thanks to the LC system to sustain high speeds for a longer duration and keep the engine temps under control. On an air cooled engine, i really doubt we can carry on with such speeds for extremely long distances and i really cannot comment about the tolerance limit or reliability of the engine internals when the revs are going crazy at the absolute limit of close to 10,000+ rpms. I hope i able to get some interesting results and we all can share and learn stuff from it. Thanks to Motozone guys for keeping the fun side alive with me FZ - X.

We shall soon get some Go Pro speed run videos recorded and i will share the same on the thread for all of us to review together.. So keep an eye on this thread... more fun stuff to follow soon....

Cheers,

Re: FZ - X Motozone tests for speed runs

Thanks buddy.

I really don't know what you are trying to convey here. And I am sure most others don't too. But the whole point of this thread is to stop those
mistakes from happening or at least minimizing them.

The mistakes you do in a swimming pool wrapped around a blown up rubber tube are miniscule in nature compared to the mistakes you do
in hot roding. Here I am not only talking about money but also your life.

In the swimming pool you have a lifeguard but out on the open road if your engine seizes suddenly and your Tyre locks at a speed above 70kmph
on a busy highway then I don't think anyone would appreciate the outcome of that mistake.

We are painstakingly, well shv18 has a blown kit and me didn't get any help whatsoever during or after the build, trying to convey that hot roding
is no child's game. We should be ready for the worst outcome too and just not expect the rosy picture.

Nobody's saying to stop hot roding but instead we are trying to educate people what they should be ready for, if god forbid something goes wrong.
This is a comprehensive experience of what to expect and how to prepare for, then start the hot roding, withstand it and then complete it with full gusto.

All i wanna say is "There are some mistakes you need to do, to learn and there are some mistakes you could clearly avoid from the experience of others".
These two are in no way related to each other.


I think I shall have a look at that 130kmph speed in the coming days, eh?

cheers...

Re: FZ - X Motozone tests for speed runs


I do agree with you buddy but people do like to cross the speed limit where there is a board mentioned 60KMPH, they dont take it as an advise or a safety precaution to avoid the accidents.. But they take it as a challenge

But whatever people do.. I am glad that there are still [MENTION=32286]psr[/MENTION], [MENTION=32641]shv18[/MENTION] and many people including you, standing firmly like that sign board on the highway to avoid the accidents

Re: FZ - X Motozone tests for speed runs

Rightly said Novice.. in today's Information age, it would be waste of resource not trying to learn by others mistakes and successes

Trip of the North, Change in Perception and FZ - X Updates, 22nd October 2013

Hi All,

Finally i finished my family trip and now i am back in Mumbai. If i may, i would like to share a little bit of my experience with all my fellow riders...

Trip to Shimla: We had taken the NH 1 road which went through UP, Haryana, Punjab and then finally we shift to NH 22 to head towards Shimla (If i remember the route correctly). The roads are simply brilliant and there is no other way to describe it! One can easily keep their respective rides/vehicles at triple digit speeds most of the time. Even when we were ascending towards Shimla, i must say the roads have been very well engineered and the corners and cambering done is top notch. However, having good roads doesnot necessarily translate to good driving sense. One has to be careful while driving/riding on these roads as i feel drivers from the opposite end simply take the name of their respective gods and dive into a blind turn without any common sense or taking into consideration that there might be traffic coming on their way. I witnessed atleast 5 - 7 close calls of such drivers about to ram into a truck while making a crazy overtaking attempt on a blind left turn curve. So any of my fellow riders, if you intend to go for a small biking trip down this lane.. bear this behaviour of the drivers uphill in mind.




Once, we reached Shimla I was taken aback by the cleanliness that prevailed throughout the city. The Himachal Pradesh Government and the local municipality has taken each and every step possible to keep this city clean and plastic free. I remember one incident where i saw one of the tourist just flinging an empty drinking water bottle on the side of the Mall road and immediately within seconds one shop keeper left his desk and picked up the bottle and put it in a dust bin. Reminds me of my last trip to Macau, China where I saw a similar punctuality and sense of being civil amongst the locals which majority of Indians seem to lack.









For all the smokers, bad news!! Himachal Pradesh has imposed a strict rule against public smoking post 2000. So if anyone is caught violating the rule especially in Shimla expect a hefty fine. I initially thought the response against this kind of rule will be lukewarm like we see in Mumbai.. but to my astonishment even the cigarette and pan selling shops here discourage you from lighting up your favourite pack anywhere near their shop. Public smoking is strictly prohibited and for once, it felt nice to see the general public following the rule.



One piece of advise though.. if one planning to come all the way here to witness the beauty of the Himalayas, you will be greatly disappointed. I would recommend visiting McLeod Ganj, Chamba via Pathankot. The view of the snow capped mountains is spectacular from that region. The image above should give you an idea about what it means to see snow capped Himalayas right from the moment you enter Himachal Pradesh via the above route mentioned.

Delhi...The changes in perspective: Well people in Mumbai and Delhi are well aware of the typical conversations striking at work, cafe and anywhere about Why Mumbai is better than Delhi, Why Delhi is better that Mumbai etc. etc. Having completed over 11 years of studies and now work in Mumbai, i too was of the same opinion that nothing beats the life in this crazy Metro city and no way in hell Delhi would come even close.. until this very trip which made me warm up to the capital city slightly. There are certain things i feel we lack severely in Mumbai and Maharashtra when compared to Delhi and the NCR region in particular:

* Roads and Infrastructure: There is a reason why it is the capital city of India. I felt in comparison to Aamchi Mumbai, the amount of detailed planning and contruction has taken place in Delhi since, the last few years.. it is commendable! One can cross over 25 - 30 kms in just 10 mins thanks to a network of roads connnecting the central Delhi. The traffic scenario is completely different when compared to Mumbai. Agreed, being a landlocked city there are unique problems associated with Mumbai. However, i now feel that the planning of New Mumbai and other places have not been done properly keeping a plan for the future growth and the way migrating population lands up here in Maharashtra. I believe we should learn a thing or two from NCR.





I had a great time catching up with my old mates at Rajiv Chowk, CP, Delhi.

* Delhi Metro: All my friends in Delhi advised me against travelling in a Metro rail during peak/rush hours. I have a feeling they have absolutely no clue about what is the real definition of rush hour on a local train is!! I won't blame them as they have never experienced the feel of the same in local trains of Mumbai where one literally has to hang for his dear life at times by his pinky finger and every inch of the compartment filled by people and luggage and out of the world putrid smells!! For a change the cleanliness in and around the Metro was something else. I was impressed with the way the train stations have been maintained by Delhi Metro. Truely commendable!!





Unlike my earlier belief of the Delhi not being safe at all and all women running for cover post 7 pm.. it was not the case. For the readers from the rest of India: It is not like what the national Print and TV media wants you to believe!! i saw plenty of girls travelling independently even post 10 pm on streets. That being said, agreed the law and order state in Delhi is not as great as in Mumbai. However, i feel it is improving slowly but steadily and will continue to do so over a period of time. To me the most surprising change was the Delhi Auto wallahs now running by the meter. My friends told me that the Delhi Traffic police has started an aggressive crackdown on errand auto drivers who refuse to run by the meter. If i were to compare the quality of life between the both cities, on everything else i would rate Delhi a notch above minus the sense of security which we get to see here in Mumbai.

Pardon the pun but do consider me to be an outsider/ tourist and the experience of Delhi is quite brief!!

My local friends were raving about Karim's, near Jama Masjid to be the best place to try out Kebabs and all other franchisee joints of the same are crap; something I have been hearing about since the last 10 years. i finally decided to put this to rest and visited the old joint along with my cousin.







To my utter disappointment, this place is overhyped! I can personally show around 10 different joints in Mumbai which offer better kebabs. And to be very frank nothing beats Lucknow's Kebabs. I have had my fare share of experience of the same in Lucknow and so far i am yet to find any other competitor coming even close to it. What can i say the little foodie inside me went with too much expectations i guess.

I hope to return to this part of the country soon..but this time on two wheels, travel extensively.. hopefully i would be able to put up a better travelogue..

Yamaha FZ - X Updates:

Well, my bike is still with Motozone and as per their initial tests, with the existing set up my bike is able to hit 116 kmph very quickly. After that the nos. come very slowly to hit a max of 130 kmph. They feel that the 15 - 40 T set up is somewhat hampering the top end. They are now going to try out polished jets and see what changes do we witness with the performance at the top end. And then at a later stage the flatside carburettors will be used to see the bump in power and the behaviour of my ride.

The engine oil consumption is consistently on the higher side which is a matter of concern for me. Mr. Vikram has updated me that the coneset which i had got replaced recently from the SVC has gone kaput. He suspects the installation of the coneset was not done properly and no proper torque ranges were followed when tightening the coneset. As a result under 1500 kms it has given away. I am thoroughly disappointed with the drop in the standards of workmanship of Kamla yamaha SVC, Mumbai over the years. Although it is not their job, i have requested Mr. Vikram to kindly replace it. I should be getting hold of my FZ - X in the coming week so shall update you guys more.

GoPro videos and data logger tests are pending.. so stay tuned folks


Cheers,

Re: Trip of the North, Change in Perception and FZ - X Updates, 22nd October 2013

Looks like the trip was one helluva fun experience. Nice to hear about your travails finally.

Finally on Saturday I had a chance to ride your bike. Had gone to meet Mr. Vikram about the work being done on my BS26 carburetor.

More on that later when i get hold of it.

So I thought lets have a ride of your bike. So took the keys from them and went with a lot of expectations.

Started the bike and off i went. First thing I noticed was the missing initial punch.

But as the revs hit 4k rpm and beyond the bike would go past 9k rpm easily fast.

Thus the 116 kmph speed was validated by myself.

Hit that speed in no time in a small stretch of the highway. But after touching that speed i couldn't help notice the bike was swaying over dangerously.

I immediately slowed down. Couldn't risk a swaying bike on a busy highway. Alongwith the cone set i suspect you shoulkd also take a look at the swing-arm bushes.

But it was real fun riding the bike and i thoroughly enjoyed it. Now I am waiting to ride it with the other goodies installed.

cheers....


Rightly said my friend. Clearly avoid whatever you could, armed with information nowadays.

Re: Trip of the North, Change in Perception and FZ - X Updates, 22nd October 2013


What you experienced was normal. With 15 - 40T the torque has spread over higher gears. The actual power starts building up from 5000 rpm onward and the punch is really strong after that. As per the digital rpm gauge meter, My bike is able to hit 11,500 - 12,000 rpms thanks to the custom multi mapped CDI as per Mr. Vikram.

I haven't laid hands on my bike for a while now so once, i get her back i would be in a better position to assess what needs replacement and what needs a bit more tinkering. I am very confident that purely for drag runs a Flatside VM 24,26/28 carb should boost the overall performance by a huge margin. But then again purely in terms of streetability i would recommend a CV carburettor anyday over the other variants. One will get a balance of power and FE range which is one of the prime factors inside city premises i guess.


Cheers,

Re: Trip of the North, Change in Perception and FZ - X Updates, 22nd October 2013

Wow!! i am overwhelmed.. The thread is now officially a sticky! I hope i am able to contribute more information for the benefit of my fellow riders...


I shall be getting hold of the GoPro video soon where my bike has achieved the 130 kmph+.. In the mean time in my upcoming posts, i shall provide more information about carburettors soon regarding why certain carburettors are better off with FZ mods and why are some not!

Cheers,
