Hi guys, I was riding my WR home after a day on the trails and the rear wheel locked up on me in 5th gear. I was pretty close to full throttle. When I finally came to a stop the bike started with the clutch pulled in but the rear wheel was still locked up. I then shut it down and got the bike home on a trailer. I'm in the process of taking the bike apart for an inspection to find out what broke. I drained the oil and the oil was grayish and cloudy. The filter had some metal particles on it but not much. I now have the engine on my workbench and when I went to knock the pin out of the piston after I removed the clips. What was interesting and alarming is that the pin was stuck to the piston. The metal from the pin had sort of welded itself to the piston. Now I'm going to need a piston and pin I'm afraid. What I'm wondering is how do I tell if my cylinder is bad? It's got some very light swirl marks in it but I think that's when I was puling the cylinder from the crankcase. There are no up/down score marks anywhere in it and it seems smooth to the touch. Any of you here ever had this kind of failure? I'll take the rest apart tomorrow after work. I need a tool to remove the stator nut and I'll probably need a puller as well to remove it. I'm going to have to split the crankcase so that I can get to see what happened to the transmission. I'm thinking that it got pretty hot because of the piston and pin situation that I just explained. Any tips and thoughts you might have would be appreciated. Thanks, Eric.
