i was riding my fourwheeler up the rode and it just quit. So when i got it back home i checked the compression and pulled the spark plug. The compression is low and the spark plug had little pieces of metal on it. Me and my dadhavent gotten to it yet but we might tomorrow but we are going to pull the head off and see what happened. What do you guys think am i gonna need to get a new piston and rings and bore it out or could it just be the rings that went or what? let me know what you guys think i am just curious of all the possibilities that could be wrong. Thanks
