Re: 77 RS clutch slipping
In the end, all of the "techniques" don't really matter. With all things considered, we know that as you pull the hand lever in you go from clutch full engaged (plates all together) to a point where the clutch is fully disengaged (plates apart). You want it so that when the hand lever is at rest, the clutch is engaged and with the lever pulled all the way back to the bars, the clutch is disengaged. You don't want it so that the moment you pull the lever, the clutch begins to disengage and you don't want it so that with the lever all the way back, the clutch is still engaged. So, there's a "sweet spot" in the middle that you're trying to find. It doesn't have to fit any of the methods...it just has to work and shift like you expect and want to feel. So you can use as much free play as you want to get that sweet spot right in the middle of the hand lever throw.

Fast. Neat. Average. Friendly. Good. Good.

I put it back together and will ride it tomorrow.

Re: 77 RS clutch slipping
Clean the splines of both parts squeaky clean then brush a TINY amount into the splines of both parts. Brushing the grease in is important. Then push the disk onto the input shaft and clean off any excess that gets squeezed out with a q-tip. I even reverse the disk and push it in again to make sure there isn't any excess that will get slung onto the disk.
Good luck,
Randy

Re: 77 RS clutch slipping
Went for a ride this morning and it slipped. I was going 75 in 5th and did a hard roll on. When it got to 5K it let loose. Got home and checked free play good, pulled the clutch arm, piston, bearing all good, was able to move the rod in and out with no hang up. I guess I have to pull it apart and measure the depth of the flywheel so if anyone has one to measure and let me know I would really appreciate it.
