[QUOTE="Nova427, post: 1353890, member: 107593"] I honestly have no idea, the bikes been blown up for about 8 years...I couldn't even tell you what kind of oil I used... I was talking to my brother, cause I couldn't remember exactly what was happeneding with the other bike I mentioned, apparently the 3 times the 125 blew up the power valves broke and fell into the motor...Each time they were replaced, they would do it again, and with the 250, the bridge part of the sleeve was broke out, I thought it was from the valve letting go, because it was up against the side of the port hitting the bridge where it was broken... I honestly don't know what to think, because I have searched tons of forums and can't find anything about this type of problem...I think I am the only one it seems to happen to... [/QUOTE]
