My motor siezed up. After removing the head i found a chunk missing from the head, a hole in my piston on the right side. I have porting done (duner port), milled head, v force 2 reeds, t5's, timing plate advanced to +4, stock carbs, k&n filters, runs race fuel mixed 32:1. All weekend long shee ran great. On the last day i was duning and shee blew up! I am getting a Noss head but im not sure on what size domes. Also need some thoughts on why shee blew in the first place.
Thanks
