Hi,
I was checking bike over today and noticed a missing nut from a bolt which was coming out of engine casing just below the points cap.
Does anyone know what bolt is for ? and the size of a replacement nut?
Thanks in advance
Brian
Looks like a 3/8 cycle thread.
I believe it's 5/16 cycle. The bolt has two purposes, it provides an attachment point for the rear mag/dyno strap but also contributes to clamping the two crankcase halves together.

Close! But no cigar.
