Not to change the subject, but I have a different question on the clutch on this bike. Bike is a 2011, 90% woods bike with all stock components, "Woods Map", running Rotella T 15W-40, non-rekluse clutch. The problem that I'm having is that in extremely tight stuff, or if I get stuck on a hill and have to slip the clutch to get going the clutch/bike tends to heat up and start engaging different. It will dis-engage fine, and will not drag, but when I go to release the clutch to take off I have little to no, what I'm going to call "slip zone". Basically when I let the clutch out it just wants to lurch and take off which makes it really hard to really control the bike in the super tight stuff. If I get out of the tight stuff and get on some open to get the bike cooled off some, the clutch will go back to working better, until I get into the tight stuff again. My question is, could there be something wrong with my plates that when they heat up they are causing this? It does gain some freeplay in the lever, but I can adjust this out when I stop and it will still do the lurching thing until it cools off. I've pulled the clutch out and the friction plates are all still right in the middle of the spec range, but I did notice that the steels do have some slight bluing on them but appear to be flat when placed on a flat surface. I'm wondering if these steels heat up and start warping causing the clutch to act up.
