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?
