PostSubject: Clutch Issue   Wed Apr 20, 2016 12:37 pm

This has happened twice now on the GRiSO, in both cases same conditions, several days apart.

Morning start up with clutch lever fully in, engine starts and immediately starts pulling forward.  Basically it feels like the clutch plate is not fully engaging.  

So I kill the engine and try to shift to neutral with the engine off, but it won't shift.  Clutch lever in and out several times, change Pazzo lever setting for more throw, nothing seems to work, until it suddenly releases.  Once it does release, operation is normal.

Possible troubleshooting would be: bleed the clutch, look for backside housing movement, other??

I'm confused that it only happened twice in 2000-miles of riding.  Wouldn't air in-line or housing movement cause more consistent issues? WTF?

Sounds like the plate may be sticking on the input shift splines.

Could it be addressed with additional plunger length to increase pressure on the hydraulic line?

Nope.you say it only happens occasionally. That means that when it's working it's fine but something is catching and causing it to jam on these rare occasions.

So, this looks like a complete bastard of a job to get to the clutch. The service/shop manual is light on detail and even calls out specific tools I haven't been able to identify (05.91.26.30, for the fork pin nut), even worse is the risk of needing special tools that aren't called out at all.

So, is this do-able for the novice mechanic or is it a job best left for the pros?
