I stripped the left crankcase oil drain bolt

I'm going to buy time-sert and need the bolt size. The manual says M6 x 1.0 (its a 08 WR450-F).


However when measured I get 8 mm width. So what is the correct size?

If youre not sure, try finding a die that the bolt fits.....


I finally had to actually measure its size with thread tester. Its M8 x 1.25

Is there enough meat to go to a 10mm bolt, if there is than I would do that instead of an insert.
