I decided to be a good boy and change my oil tonight. I removed the plugs, drained the oil...all was going well. When I was reinstalling the plugs, I got a little too excited with the allen wrench on the oil filter drain plug, and I think it stripped. I can thread the bolt all the way to the bottom, but it won't get very tight. Once the bolt gets to the bottom it just spins. The bike is a 2006 YZ 450. How do I fix this?
