Question QUESTION: Hey Rich,
Its my first bike, a 1982 v45 Sabre. The clutch was slipping at hard revs, I figured that this was due to a leak in the slave cylinder since I appeared to be loosing fluid from the slave. I replaced it but after some riding, it has began to slip again. I recently sold a moped to a Harley mechanic whom told me that this was a simple fix, that the clutch just needed adjustment. I have the manual so I thought that id just look it up in there, but from what I can see there is no mention of clutch adjustment.
Its weird, if I bleed the slave, then the problem temporarily goes away, but then will come back after 30 or so miles. The rest of the bike seems to be in pretty good condition, so I am planning on packing it up and heading south for the winter (hate this cold weather), but would like to take care of this problem first.
Any help would be greatly appreciated as there seems to be a major lack of "vintage" motorcycle mechanics around here to look at the bike.
Take care, Mike.
ANSWER: Mike, you have to rebuild the slave cylinder on teh left side of the motor. When you take it apart you'll find it's all gummed up. If you clean that up good and then refill with fresh brake fluid, thing should work normally.
Regards
Rich
PS there is no adjustment on that hydraulic clutch

QUESTION: that's the thing though, its a brand new slave and im still having these problems.
Answer Does the slave cylinder move freely in the bore? There's a spring in that bore. If the piston won't move freely with just the force of that spring, it still bound up in the bore. The problem is that the piston is applying pressure to the clutch and I think as the engine heats up, the fluid expands and disengages the clutch.
