    Thank you!!! Confusion seems to trouble me when it comes to specific bolt sizes, thread pitches, etc. I'll grab an m6 x 1 mm. kit and gett'r done! Thanx!

    Yes! Invest in a real kit! as the drill is a few decimals off standard, as is the thread of the tap! Great investment as you have a Kawasaki engine!
    Even though, on those 2 end bolts!! I have been known to tap a US SAE 1/4" tap through before the heli-coil.
    Your choice!
    Good luck!

    Thanks z1kzonly!! I'll try the US 1/4" tap trick and see if that'll work.
