Clutch issues

Post by Bama704 » Mon Nov 20, 2017 8:16 am

Hey y'all, I'm having issues with my clutch. I have done all the adjustments on my '65 CA95 to no avail. There always seems to be some type of pressure on the clutch. It idles fine and when I pull in the clutch lever and engage 1st gear it will lurch forward and die. If I adjust the clutch some more it doesn't lurch forward (as much) but will die if I don't give it some gas and hold the brake to prevent it from moving forward.

With all that said, the clutch is like an on/off switch. There is no feathering of the clutch, hold the clutch lever in and it is disengaged, let it go it is engaged. You can not stall the bike out. And I promise I have adjusted the clutch MANY times. I have spent hours being frustrated with this.

At this point should I just try to replace the clutch plates and springs? What do y'all think I should do?

I’d suspect that not all of your clutch plates are free. Take the clutch apart to unstick and clean the plates. You can evaluate their condition while you’re doing it.

If I am having a hard time getting the side cover off, would you recommend using heat on each screw head to loosen them up? I have tried an impact driver with no good results.

Others may disagree, but no, I would not use heat. If you are absolutely sure that your impact screwdriver with a JIS bit will not get a cover screw out, drill the head off. The remaining screw shaft will come out very easily once you’ve taken the cover off. Get yourself another set of case screws. Many vendors sell them in a pack.

The thing with impact screwdrivers is to make sure the bit really fits the screw head properly. Use the largest bit that fits nice and snug, make sure the screw head is totally clear of dirt, tap the bit into the screw head to ensure it really does fully bottom, only then use the driver remembering to preload it first and hold the tension in the direction to undo it, then give it a good clout. Not lots of little taps, one good clout. If this fails then drilling the head off is the final solution.

I agree, no heat but I use a dead-blow hammer on the impact driver to make sure that there is no 'bounce-out'. It really makes a big difference.

Failing everything else a sharp chisel applied tangentially to the screw head after making a nice litlle slot by hitting the head straight on first. (harder to describe than do).

That always gets 'em out.

Good news is that I was able to get the screws out, using the chisel was a great method.

Where would I find a set of case screws? Where would I be able to find new clutch/friction plates and screws from?
