Hi guys,first time on this forum,i opened up the head of my banshee and found that the left side piston had a hole on top of it and then looked at the right side and it almost started to have a hole on that side too,my question is why did it have a hole on top of the piston,i was thinking that my water pump went out and got too hot. It needed new pistons anyways.3 1/2 years with these pistons.What do you guys think what made this happen? 97 banshee coolhead 21cc domes wiseco pistons (.020) 207 above sea level
