ok heres the deal.i melted a piston on the shee a while back.ive told this before but,,,,,,,,,,, people have been telling me that by the looks of my piston(burnt down on the top towrd exhaust port, and it almost looks shredded all the way around it like the bore was to small)anyway i figure if it was a lower end air leak it would have smoked bothe sides but only the right bank was fucked up other side was fine.could it be a leak with a o-ring on the head?im fuckin baffled, i dont want to just put it back together and have it do the same thing again.its like that one side got way to hot but i cant figure out how that is possible.sorry about spelling and grammer.any input would help.please ask ?s
