So my kick start on my blaster went out and it ended up my piston being shot. I'm going to have a friend of mind rebuild my top-end, but I'm ordering the parts. My question is; For a top end kit, how do I know if I'll need a new cylinder jug/head? The head is the part that'd be marked up by from the piston, right? I know these questions should be super easy, I'm just not suited for this kind of knowledge lol. I need help finding out what I need to order, if anyone has any suggestions.
