Topic: Mirror Thread Pitch

[chopper62]

Hi All, i need the pitch of the thread for the mirrors for my 400/4 1977. I need to helicoil the thread on the right hand handlebar.
I know its 10mm but is it 1mm or 1.5 mm pitch.

I’ve used this sheet in the past to check thread pitch.  Just need to print a copy...
