I'm not really sure about this , Just a theory , but maybe the bike is not pulling above 108kmph is because it's running too lean ? ( as most aftermarket filters tend to do this ) so if he adjusts the A/F ratio to make it richer it might just be alright ...

Bad Idea.

Upjetting the carburetor will solve this problem also expect a loss in mileage with upjetting.

No.

Yes.

No idea about the Stock jet size,normally 10 to 15 units + stock jet i guess.
ie if the stock is 100,then the jet for K&n will be 110 or 115.

Yes,its because he is running lean.

Thats NO,Adjusting AFR wont work in this case.He has to get the carb upjetted with optimum size jets.ie change the jets with bigger ones.

Hmmm... Theory busted ... Better option , revert to stock .

Even i recommends the same.

Stock is always always the best.

Does the bike miss beats at 108Kmph??? If it's missing beats then the AFR being lean has a play in it, else if its just the brick wall effect, then something else's to be blamed.

Info On clutch

Hey ppl

I wanted to know after what time interval or how many Km odo reading should 1 change the Clutch n the pressure plates.
And how does 1 know it is not working properly...i mean what r the symptoms

I dont know all this cos its my 1st bike.

31000+ on ODO

Normally they're changed when the bike fails to reach previous speeds in the same RPM. etc, Mine reaches [email protected] if it reaches [email protected] then its time for a clutch & tranny overhaul.

Signs for Clutch Replacement in FZ

Hey Bro,

As per my earlier conversation with the head mechanic at yamaha workshop, the life of a clutch plate with moderate riding (insane thrashing plus city riding) is around 25-30,000 kms. The usual signs of clutch going kaput are:

1) One may notice FZ's bottom end is lacking.
2) The clutch Doesn't engage until the lever is almost all the way out.
3) A burning smell coming from the engine.
4) Hard to find neutral.
5) Clutch slipping. This is a technique i remember reading somewhere: Get your bike going in a higher gear, 3rd or 4th, pull the clutch lever in, rev the engine, release the clutch lever quickly. The clutch should engage quickly, if it slips momentarily before completely engaging, it is a sure shot sign that clutch plates are getting weak.

Others are free to add anything above which i may have left out.


Replacing the clutch plates is not that expensive around 600-700 bucks if i remember correctly. Since your FZ has hit 31k.. here is the previous post you may look into as posted earlier by me and Lucky Luke: http://www.xbhp.com/talkies/motorcyc...tml#post724070 . Please note that the prices mentioned in the post are just approximates. The actual parts prices may be cheaper or more.

Cheers

Hey good to see you back on thread

I am not too sure if this is a proper troubleshooting from my end but more or less i feel somehow either the cone set installation is not done properly or the replacement one is faulty. Have you checked your rear shocks if they are ok?

OT R165 & FZ Parts: A friend of mine is going to blore this weekend to get his 2nd hand R15 completely souped up by Joel, Race Concepts. His bike is not exactly in the best condition as the previous owner has not maintained it properly. However, both me and him have had a long chat with Joel Anna and Joel has assured that his team will take care of all the problems and also post upgrades, the new R165 will be generating 28-29 bhp on the rear wheel and is indeed a ninja killer.

I have also requested my friend to click the pics of whole process of dismantling to installation of all the upgrades in his R15 plus pics of the new parts of FZ including the prototype programmable CDI. Shall keep you all posted.

Cheers

She is doing great..but the performance past 100 is still lacking..planning to go for exhaust next,lets see..
nand even I was planning to go full monty with the mods,but then the v2 came,then rumours of 250s...so not really sure

28-29 bhp How much power would a fully souped Fz revving upto 11500 rpm produce??

Thanks man. he is in love with the sound. the bike also feels a lot more free-revving. changing to stock is a no-go. And about the jets. i read somewhere that there are two jets (main and pilot) which have to be upgraded, which just complicates things further. so i guess 110 or 115 it is. Mileage is a no-brainer now. throttle-satisfaction is everything! anyway, how much of a hit should we expect after changing the jet??

Trust me the exhaust does work .. mine is hitting 106 in no time!! Yesterday just as a test i had filled the rear to 35 psi and front 28... the way she reached the top end was lightning fast!! BTW i did all that with the DB killer on.. my stupid Allen key broke.. shitty quality.. so haven't been able to take the DB killer off and me being lazy is adding it all up to it!!

regarding custom CDI you better ask the guru himself...his race version R15 produce 31 bhp if i remember correctly BTW with the custom ECU it hits 12,000 rpm!!

Can the fz's head take that many revs?? It only has two valves. not made for hard revving. Plus, streetbikes are meant to ride on the torque curve right?? everything said and done, who wouldn't want a high revving fz! Go Joel!!
