Run her til she dies, Beastly! I had some major junk come out of mine when I put clutches in it. I changed the oil & rode it... Pulled it apart for a freshen up & found a cracked/chipped piston & a few shavings in the oil filter again. It wasn't as bad as the 1st time but still. What ya gonna do though, ya know. It runs good but has alot of time on it. I'm just gonna run it til it gives up & maybe make this a stroker motor when it's done.
