Hey i was wondering if i could fit a 77 or a 78 mm piston into a stock sleeve on my 300ex or would the cylinder walls be too thin?what is the biggest i could put in?it has a 75mm piston in it right now but it needs to be bored out.Also what jettin do you guys recommend for riding at 500 feet above sea level with the baffel out and no airbox lid?


P.S. I also have a stock bore wiseco high comp piston that i bought for $140 CAN and will sell for $70CAN it has a broken ring but otherwise is brand new. Email me for more info at canada_kicks_usa_a**_101@hotmail.com plz

77 should be ok.
78 would be borderline, but should be fine.
80 need sleeve.
