96bansheepilot Posted April 29, 2006 Report Share Posted April 29, 2006 i had a buddy's banshee sieze up on him cuz the left piston skirt shattered. i was wondering if he mabye had problems because he liked to run 100 octane fuel. his timing was stock and i'm not sure what his compression was.he does have an aftermarket head. but what we are going with now is +4 timing, 100 octane fuel and 21cc domes. his compression should be around 160-165lbs. does this seem ok? also, what causes a piston skirt to shatter? just a defect or thing that happens from time to time? would dirt in the engine cause a piston skirt to shatter? i would think that it would just wear down the cylinder walls if dirt got in the engine. the only reason why i say this is cuz his filter fell off when we were trail riding that day it shattered. put in your two cents please. would over heating cause the piston to go?

Banshee~ Posted April 29, 2006 Report Share Posted April 29, 2006 You should be fine running 100 octane with 160-165. The dirt getting into the engine is not good for it and might have caused it. You dont want any dirt to get in there. What kind of oil/gas ratio was he running? Quote Link to comment Share on other sites More sharing options...
