Hi Everyone,
Sorry in advanced for the long thread.
I finished an 850 project last August, and I put about 200 miles on it before I had to put it away for the season. I inherited this bike with the gearbox and engine “completed” and in a frame. The rest I assembled with an assortment of used and new. It was an eventful 200 miles with a blown belt drive and a stripped exhaust thread in the head (I replaced with a spare RH10 head that I had). In addition, there was the usual tuning, retorquing, and oil leak chasing. I was able to remedy all of these issues, however I was pulling my hair out trying to get a sensible clutch. It was very “On and off”. I replaced the clutch center as the existing centre has some signs of wear, scuffed and cleaned the bronze clutch plates, ensured my dyno-dave seal was keeping out oil, and set clutch multiple time as per manual. Nothing worked. After I had my bike put to bed for the winter, I looked at my gearbox cover, and realized that the outer cover on the bike was from an earlier 750, with the cable hole located further to the rear. I then realized that the cable was not fully seated in the hole. I know this is a very stupid and obvious mistake, however at some point along my journey, I overlooked it. So with clutch cable properly inserted, operating arm in place, I once again set up clutch as per manual. At this point it seemed a little better, but nowhere near as easy as my 750. This AM I removed the outer cover, as I wanted to replace it with a proper 850 cover with the cable hole further towards the front of the bike. I was thinking that the cable would have less of an angle entering the gearbox, and would result in an easier clutch. While removing the outer cover, the operating lever fell, and it jammed in place. I could not free it, and I did not want to use force. I removed the screw that keeps the clutch operating roller in place, and lightly tapped out the operating arm. When I picked up the pieces, I think I may have found the root cause of my clutch problem. Has anyone seen this happen to the roller before?
All the best,
Gatsby
