919 problem clutch???

So here is my problem ive had my niner for about 6000miles and everything was running great. Then last weekend i went to grab a handfull and the Rpm went up but the bike did not speed up like it should.

Im guessing this is the clutch slipping.
when i got the bike it had repsol stunt bars on it and the clutch cable does not line up like i would like it to but ive always had free play and never had a problem shifting
any ideas anyone had this problem.

its hard to describe the feel it gives but imagine yourself and 5000rpm and the engine jumps up a grand or two but my tire does not pick up like it should.

thanks for your time.

Was it in neutral? I kid... but seriously, does it shift through the gears ok? you can try adjusting your cable tension. do you lubricate your control cables? is the clutch cable binding up at all?

ok, that IS clutch slippage...which could be caused by weak clutch springs, but more likely your clutch cable is binding up due to age & lack of lubrication or is adjusted too tight. If the cable doesn't slide freely, it can cause the clutch to not engage fully, particularly under heavy load. Hopefully that's all it is, but start with the easy/cheap problems to fix first!

Clutch slippage will be most noticeable in high gears like 5th and 6th.

As Shadow already said, check the adjustment and lube the cable.

He says it has free play, so the clutch could very well be shotski. If it is shot, it is either from abuse, hmmm, wheelie bar.... that can't be it. Or someone put the wrong kind of Mobile 1 in the engine.

Changing the clutch fibers is pretty easy, and relativly cheap, about $70.

the arm that the bottom end of the cable is attatched to should have a little front to back play,mine is about 1/8".if it doesnt that could make the clutch slip i think.

Is your oil specified as "energy conserving"? If it is, that's your problem. Energy conserving oil has friction reducing additives that cause slipping in wet clutch applications.

It might be reversible if this is your problem but it might be too late.

Also, make sure you have free play at the clutch end of the cable. In other words, the cable could be binding somewhere and not fully releasing tension on the clutch mechanism.

Whatever the cause, riding very much with a sliiping clutch will cook the plates and require replacement.

Perfect, cable is better than clutch.

another thing I found out the hard way, you NEED to keep em lubed, mine locked up after i got caught in a rain storm. Lubed it up and its fine now may wanna consider tryin to lube yours if its not too far gone some PB blaster and some ATF goes along way...

thats all i use on my cables is synthetic ATF... works AMAZING.

take a thumb of a latex glove, cut it off at the palm of the hand so you just have the thumb condom lookin thing... put a small slit in the tip of it, and slide it over w/e cable all the way to ~ 1/2in onto the cable housing... wrap with electrical tape to create a seal... pour some aft into the open end of the thumb, then wrap up the end to create a lil balloon of aft... and gently squeeze... the aft will go right down the cable and no mess!

I'm glad to hear that's all it was. The old cable may not completely shot, if you lube it up it should free up within the cable housing and be fine for further use!

Good job!
