Ok, have a bit of a problem here.. Got an 01 YZ426F.. The hex bolt for the oil filter cover won't tighten all the way down, its stripped. Only tightens down a little bit but it doesn't feal like its enough.. What can I do? Run a lil longer bolt to reach the undamaged threads or what? Not sure how to fix this :cry: :cry: :cry: :cry:

Mine has been like that since Sept 2002!!

I just make sure its the last bolt I put back in and I use teflon tape on the threads......never a leak and still going. I just snug it down when I put that bolt in.

If your not comfortable with that then heli coil it.

I got a bolt from the yamaha dealership that is about 1/4 inch longer then the stock bolt and I put it in with no problems and it tightened down and no leaks.. Wouldn't that work? The threads go back farther then what the stock bolt reaches or am I blocking something that I'm not aware of?
