[QUOTE="crrod, post: 1092474, member: 71636"] Well, I am cleaning the exhaust valves at the moment. There di not appear to be any clearance between the E-clip and the valve guide, but I decided to pull them anyways. There is some carbon build up on both the end of the valve and the guides. The linkage was operating smoothly. I examined the piston, ring and cylinder (what I could see of everything through the exhaust port, and the vavle openings), and everything looked nice and shiny. No marks anywhere on the piston or ring (only a single ring), again from what I could view. I could still see the cross hatch marks in the cylinder. I warmed the bike up before I tore it down to check the compression. The guage I was using would register 120 PSI with every check. I will recheck after assembling the cleaned exhaust valves (hoping it improves a tad). I am suspecting that the engine hasn't ever been in to, there are no tale tell signs of a wrench ever having been on any of the nuts and bolts. I am going to order a new top end set for it and put it in when I have a free weekend. But for now, will ride it the way it is, taking it easy. [/QUOTE]
