I just helped a friend tear down his sons Blaster last weekend. The top ring is gone...........and the sleeve is ate up pretty good around the exhaust port. I think he will need to go to a .060" over piston to clean it up, does Wiseco make .080" and .100" pistons for the Blaster too? I hate to get it bored if it has no overbore sizes left after that when we can probably pick up a good jug off of Ebay.
What else should we do while we are in there, headwork & timing? Anything else?
