Clutch arm play adjustment
« on: May 28, 2022, 11:11:39 AM »
I installed a new clutch arm, 89 update kit, oem clutch discs, cr500 springs w/washers also a new basket. Its about 1/4” seems excessive but I couldn’t get it shorter and used 2 of the washers that come in the 89 kit and with 3 there was no play. Do you think it’s ok where it is? I have the cable adjusted properly and the clutch grabs right away and goes into gear smoothly. I just didn’t like that the arm isn’t exactly at 90deg and it’s got a little more play than I’d like.

Did the update kit come with the longer push rod?

Yes it did. Pressure plate, washer, top hat piece, needle bearing and rod. I bought another kit just to get the additional washer because I figured I’d need it. I bought a slightly thicker washer at a hardware store but was afraid to use it since it wasn’t hardened steel. With that washer it was lined up perfect with minimal arm travel. All the parts are brand new except the center clutch hub. I have a video showing the arm travel but it won’t let me post it due to size.

I did a thread on this a few years ago. I was offering different thickness of stainless steel washers to fine tune after clutch update. Looks like you are where you need to be.

I searched this a lot and saw that post. It’s really close but wanted to get it perfect since I spent so much time trying to get it spaced correctly. I tested the clutch in the shop yesterday and it seems to work well so I’ll leave it alone for now. The clutch pull is hard and I have pretty solid forearms but i could see it being a workout after an hr ride.I’ll lube the new cable and grease the new lever/perch and see if that helps at all.

I lubed the new cable and put some anti seize on the lever pivot and the after riding a little it definitely softened up the lever pull. I guess the plates were stuck together and some oil splashing around loosened them. The old clutch wasn’t bad but it pulls much harder with the new setup. Also put in a rebuilt CB since the bearing was a little loose and the motor sounds much better. It almost has a gear whine sound now and vibrates less.
