The rear brake bolt on the 2006 YZ450f is another fine piece of engineering. The rear brake bolts into the frame, now the frame threads are stripped and I'm looking for options. I don't really want to remove the motor and have it welded shut and a new bolt hole drilled. Isn't there some kind of "liquid aluminum" that can be used to close the useless hole, then filed clean, drilled and a new hole tapped? How about some way to keep the bolt in place without allot of re-engineering? This is a pain in the elbow.
