hellow all, im new to the threads and thanks for having me. So here goes. I got a 02 YZ426f about 6 months ago, it is a great bike with many new upgrades, the guy i got it from took great care of the bike and put a new top end on the bike before i got it. ( i got the paper work on the rebuild) it had 2.5 hours on the bike when i got it. (hour meeter on the bike was installed with rebuild) the bike also has a hot cams cam on it, and a shop adjusted the valves with the new cam. The problem is, i took the bike out started it and warmed it up, made a few passes on the street just messing around and the bike died, it didnt make any funny noises or anything, itryed to start the bke and it wouldnt start, i kicked and kicked and it wouldnt start, i looked it over and couldnt find anything wrong with it, i did a compression test on it and its a big ZERO. the motor has 4.5 hours on it. can someone give me a link to valve specs and the step by step adjustment or have an idea whats going on. sorry this post isint real organised but i need help thanks all.
