Dirt bike engine crack
 

I have a '93 XR250 with a 2 inch crack near the shift peddle. The guy that I bought it from used some JB Weld to stop it from leaking, but it started leaking again. Should I re-apply the JB Weld or should I consider trying something else? I'm not opposed to pulling the motor and doing some major shit to it if that's required.

*hopes for quick easy fix*

Well, from the thread title I was going to suggest JB weld, so I'll stick with that.

If JB weld works fine just use it. For how little JB weld costs and how easy it is to use. I would just use it since replacing an engine case can be a pain in the ass and who nows how big of a pain would it be to find the case for cheap? Or even if it can be welded?
