EDIT: SOLVED, M8x1.25

had to remove one nut, ride the thing, and test it out there. @steelrider made me do it

TL;DR: I need to know the thread and pitch for the exhaust/header stud as mine are gone for one of the cylinders

Backstory: I was cleaning the coolant reservoir and noticed one of my headers didnt have ANY nuts on it and the flange just flopping around.
Ive been running it for two weeks like that (thats when I got the bike) and havent really had any issues, but want it patched

I know on RevZilla this is the part number (90179-08410-00) but I mean I have Lowe’s as my neighbor sooo ¯\_(ツ)_/¯

According to the service manual, the nuts that go on those studs are 8mm, but no spec is given for the thread pitch.

My suggestion would be to take off one of the other nuts and take it with you to Lowe's, then see which thread pitch works with the nut.
