I just pulled the head off of my daughters blaster it just stopped running on her. any how i pulled the head off and the top of the piston looke great but looking down the cylnder walls i can see and feel grooving fairly heavy. my question is is this normal? the bike was making some top end noise mabe piston slap? is this common we bought it used so dont know much on hrs on the motor. any information would be helpful
think i will port it while it is apart too
