Stripped the Crank?

[bfogelma]

I have a 01 YZ426 and am replacing my flywheel with a WR flywheel, and i think i may have stripped the center nut. This fastens onto the crank right? How hard is it to do? What is the likelihood its the bolt thats stripped not the crank?

Can this be fixed without replacing the crank?

You have two options, buy the left side of crank or cut the stud off flush and drill hole, tap and install a stud. Any shop can help you out.
