2006 Te 450 Oil Level

Hey folks!
New to the board here. 1st time posting. I have the bike mentioned in the title and can’t seem to get my screw that used to check the oil level to come out. It appears it was a 5mm hex before some jerk before me stripped it to hell. I’m able to get a grip with a rubber band and an Allen wrench but the bolt just free spins. I’ve made sure to turn enough times to know somethings not right but now I’m worried about little metal shavings getting in my oil and gears. Anyone have any ideas? I thought about drilling it out but that seems like it should be last resort. Thanks in advance!

You could clean it up and glue an allen key into the head so you can pull while turning to get it out. You will need to drill and tap to put a coil / insert (or bigger screw) in.

Use a drill as small as you can, sligthly bigger than the Allen key. Hammer down a Torx key of right dimension and unscrew. Broblem solved .
