anyone know the thread pitch of the 12mm nut that secures the water pump drive to the crankshaft?

I don't have a pitch gauge thingy.......

Ta.

According to my "pitch gauge thingy", it's 1.25mm.

I just pulled the side cover off and removed the starter gear etc just to check. That's not completely untrue, but what I didn't say was that I actually took it off to check why there was some slop in the timing and it turned out to be the three staked screws had come loose. But since it had to come apart, I measured it anyway.

Thanks Richard.
