I'm having some trouble with my clutch/transmission on my 1966 CA77. I am not familiar with clutches or transmissions and I just don't know where to start and don't want to rip more apart then I need to. The problem I'm having is that when I pull in the clutch and go to shift into gear I hear a grinding/clicking noise. I thought the clutch might not be engaging enough so I had tried to adjust the clutch both at the handle and the case with the same result. I know I'm probably gonna have to pull the cover off but what should I be looking for? Is this something where I need to get into the clutch plates and examine them?
The bike has been sitting for quite a few years. I did change the oil and I've got the motor running but I think I need to do some tweaking on that. The transmission/clutch issue is really the last thing I need to get worked out before she's ready to take for a ride.
1966 ca77 Transmission/Clutch Issues
Re: 1966 ca77 Transmission/Clutch IssuesDoes the noise result from the action of pulling the clutch lever? Or as you are attempting to shift?
Hmm. Sounds like the clutch plates are stuck together so the clutch is never truly disengaged even with the lever pulled. Common for an old bike that's been sitting. Try starting the bike while it is in gear but with the clutch lever pulled. If the bike wants to lurch, your plates are stuck.
Some guys have tricks to unstick the plates without removing the side cover but I can't remember the specifics.
YA must remove the cover, spring bolts then remove the plates ya can and if the wires are still there remove them.
When ya have all the plates out I recommend ya use a wire wheel on a bench grinder to remove any rust or if ya don't have one us 100+- grit to break the rust. . ...........lm
