Rmz 250 replacing crank

Recommended Posts

Hi all, gonna be reassembling a dead crankshaft with a friend once I get the parts, was just wondering if anyone has any tips on splitting a case for one of these. I find it worth to do because every thing else in the motor is in pristine condition so I got lucky when it locked up on me at the track.

Never done this before, but my friend has many times but mostly for 2 strokes. Crankshaft Similiar at all to just a regular bottom end rebuild? Or since its a 250f will anything be slightly different down there? Seems like it shouldn't be

Itll split easier than a two stroke most of the time. Your main difference will be the crank balancer. Transmission setup is the same. If your buddy has done 2 strokes hell be able to do this bike.
