I sheared one of the two M6 bolts that hold the gearbox onto the motor - I'd used too much threadlock and had to use an impact screwdriver on it to undo it and the head sheared off and I had to drill the bolt out. I found that all the gearbox bolts are 0.9 pitch thread which is so unusual that nobody in Australia makes a tap & dye of that pitch. I think all the Honda threads are 0.9mm pitch which is very unusual. I got around it by tapping a standard 1.0 pitch thread and using a standard bolt.
I wonder why Honda use such an unusual pitch - it's almost as weird as Harley Davidson who are famous for their weird bolts.
The lesson here is to be sparing with red threadlock!!
