[QUOTE="MilkJuGGz, post: 468320, member: 29470"] Hey everyone, I have a 96 WR250 that has an unknown amount of hours on the top end (bought used). I've been getting good compression and power, so I did not tear down the top to check the tolerances. Well, I wish I had! I think the piston shattered. I don't know if the preceeding events had anything to do with it. I had just dumped the bike in a sharp turn (nothing hard). After a minute of riding later, the engine started bogging so I switched to my **** to reserve. Then the engine starts running normal for about... oh 20 seconds, then it starts rattling really bad. This was at about 1/8 throttle and I was going very slow. I stop, check to make sure it's not some debris caught in my wheel, and start back up. Bam engine starts rattling like popcorn. I go about 20 feet in 1st and then stop again. I decided not to start the bike back up so I walked back to my truck. Cycling the kickstarter yields a slight grinding noise within the engine, but lacks compression. There are no hitches and it's quite smooth though. Did I just shatter my piston? My wallet says no I didn't, but I'm starting to come to terms with it. :ugg: I'm doing the top end tomorrow to see what kind of damage was done. Does a low speed failure like this usually result in cato$trophic cylinder damage? Is there a chance that it's relatively undamaged? That would piss me off to need to get bored and replated cuz I just bought a standard size piston. alsdjflkasdjf !!!!!! Arrgh, thanks for any insight. ~JuGGz [/QUOTE]
