Video: How To Repair A Cracked Crankcase Cover On Your Dirt Bike

I Put A Hole My Crankcase Cover Because I Crash A Lot

I’ve cracked a few crankcase covers over the years, but this is the first time I’ve managed to crack one from inside of the cover.

I pulled the cover and found that the shift shaft was the cause of my new case breather.

I must have laid my bike down in just the wrong angle to punch the shaft hard enough against the case to break.

So if you find yourself with a fresh crack in your cover, here’s how to fix it.
