Title: Clutch slipping at wide open throttle?
Post by: Mister Tee on July 11, 2011, 02:28:04 PM
Okay this is the second time this has happened.  I launched hard on the straightaway, wide open throttle winding it up to near redline, shifted to third, locked up the clutch, and as the revs neared redline, there was some weirdness going on that felt like the clutch slipping, and I had to back off to lock it back up.  Anybody else have this happen?

Fried clutch?  I'm pretty easy on it and the bike has barely over 10K.

It may be worn out in 10K miles, it all depends on how it was used. Some folks get more mileage out of wear items than others; 10K is a little short IMO but a clutch should not slip once fully engaged (released) under any circumstances. The other possibility is that there is something preventing the clutch itself from fully engaging; a sticking clutch slave cylinder or master cylinder, a clogged master cylinder reservoir port, etc. But again, the clutch should simply not slip at all once it is released.

I just posted about the same issue last week sometime. I've got a Red '09 but mine did the same thing at about 5-6 1/2k RPMS. Kinda felt like either a loss of power at the wheel or like the tire was sliding but I'm almost positive it wasn't the latter. I've tried to get it to happen again but no luck yet. The engine continued to rev but just a loss of power at the wheel...strange indeed.  ???

+1 That would be my guess as well.

Did you even resolve your problem? The OP's issue seems different since it occurs near redline.

He was just clearing his C14's lungs.  I don't abuse my bike, but it will hit 10,000 rpm a couple times a week.

Is like saying you watch what you eat, but you eat Big Macs a few times a week...?

or

Is like saying you don't drink during the week, but man I get f#$ked up on the weekend!

Nope, its like saying that I use my bike like it was intended to be used.  Not abused.  I also don't baby it, because what fun would that be. 

Are you the kind of guy that only runs your bike 4,000 rpm and holds up the Prius behind you.  ;D

You say this as if there's something wrong with it.    8)

Nothing wrong with it if you are doing it. Just don't tell us that you are easy on the bike when you are not. That's what Im saying.

True. I was pushing mine at a moderately hard acceleration when it happened but not quite redline. I haven't yet been able to replicate the problem to analyze it further. Perhaps I'll try it again on the ride home today.

It's only happened two (maybe three) times since I've had the bike.  I just switched to full synthetic last oil change.  It did it once or twice with the old oil and once with the new oil.  I don't think it's the oil.

That exactly!

Lighting up the rear tire "feels" like the clutch slipping as you "ease" into the rev limiter.
Just a guess...  :o

What oil?  If it is any of the extended mileage type you may have the slippage as described or if you have ever added any of the car oil additives.  I did have this happen-twice, the Hippo hands collapesed onto the clutch lever enough to cause slippage, also lit the brake light.  Needless to say, I have Bakers hand wings, still my fav farkle to date.  I also didnt see if you have any aftermarket style levers.  At 10k I wouldnt expect any wear related issues, less of course you always launch hard, as in strip type runs ;D  I'm at 49,000 miles, run 'bout as hard as most anyone and clutch is working great.
