i am going to go look at a blaster for sale it looks like a basket case the guy claims the piston skirt shattered and it's tore apart it sounds weird to me the pics he sent me it has a stock exhaust on it and is advertised as big bore bored to 250cc that os the first red flag i am thinking it's a stock cyl that has just been bored over to? .20 or what?? any how if it is a big bore (probably not)how do i tell is their castings to identify the cylnder? or a company name? i have never delt with a big bore kit before?????????:-/:-/:-/:-/
