I don't know if this is the best place to ask this question, but here goes - I seemed to have stripped the threads of the bottem allen bolt for my oil filter cover on my 06 450. When I go to tighten it, it almost gets tight and it just keeps on turning. I have always tried to be careful when doing this, and can't believe that it happened. I did ride after this, and it stayed in place with no oil leaking. Three questions, if anyone can help - 1. How hard will it be to fix? 2. How can I keep it from happening again? 3. Do I need to fix it if it stays in place with no oil leaking? Thanks for all replies in advance.
