Bearing replacement help. Ralph, Bill??
I had a major brain fart and tweaked the wrong needle on a 150cc twin. The result was it got hot enough to quit in flight. 6 flights later it has rod knock. I have it apart and really can't see any damage but I'm fairly sure the rod bearings are shot. My question is can the crank be pulled apart and the lower rod bearings replaced and the crank pressed back together or is the engine scrap? This is an EVO 150 not to be confused with Evolution and parts are not available so if this requires a new crank it's headed for the garbage can. Thanks guys for the replies.
