Bad clutch (master/slave?)

[nigel dabster]

was just thinking what glen said about the small centre bolt certainly on a gasser symptoms would match.

Logically hydaulics would not cause immediate changes you descrbe?

I'll suggest one final thing.  I have a Clake OLC master cylinder.  The free-play adjustment on that is critical.   There's almost no range of adjustment between the clutch not slipping and it disengaging completely.   And it can exhibit similar lever effects to those you mentioned.

Heffergm, did you solve your clutch problem?  Your post prompted me to work on my Clake.  I installed a new piston assembly and this was a magical fix. Nothing appears to be wrong with the old seals, however they may have grown excessively in diameter.  It's a 9.5mm bore.  The seal diameter measured about 10mm.  Two other used piston seals I have measure 9.7 (from mineral oil)  and 9.8mm (from DOT4).  So maybe just a lot of seal drag in my case?

The short answer is, they all seem to work this way (meaning, AJP clutch master on these Sherco's).

I tried two other '19 Sherco's last week and they both act the same. We put another master cylinder on the bike (making this master #3) and while initially it seemed to not exhibit the same behavior, by the end of the day it was exactly as it had been before. I didn't notice the bite point moving around or have any other issues with the clutch, so I've decided to just ignore it.
