Okay i know its not a blaster but i figured yous guys minght know. I have a 98 rm 250 that blew a piston skirt into the bottom end and locked it up. I took engine out turned it upside down and kicked it over a couple times then put atf in it and washed it out and now it turns over fine and i cant see any metal at all. Am i able to just buy a new top end and run it?
