the lower rod bearing went again but after i found little bearing balls in the spark plug i kept running it. this is what happens. Also the top ring got stuck.
it only had 20 hrs if that. so i know you should teardown when you find those but im like screw it and rode for about another month or so. yea im dumb sometimes
looks like the piston i pulled out of the old motor in my 440 arctic crap. I still remember the first time i blew up my blaster though, 1/3 of the crown on the piston was gone and the skirt was cracked XD
