2000 RM 80 cylinder head stud

[motoplat]

Can anyone verify the thread pitch for a 2000 RM 80 cylinder head stud? I think it is 8mm x 1.25 but it could be fine thread x 1.00.

I'm pretty sure it's a coarse thread. Do you have either the cylinder or the stud? Try a bolt or nut with a known pitch to test it out.
