Exhaust mounts - What size bolts?

[maxpower3]

I can't for the life of me figure out what size bolt belongs in the exhaust mounts (2 per mount, 2 sides). I think I had a few 9/16ths bolts in there, but they didn't seem quite right. Also, are the threads fine or coarse?

Thanks in advance.

Not quite right, huh? Maybe because these bikes are metric, lol? That is a rather special bolt if I'm thinking of the same one (the 2 side by side under the engine). I think it's a fine thread M10 with a washer incorporated into the head.

10mm-1.25 to be exact. Pretty common Japanese thread.

Thanks. I used 10x1.25 pitch.

They used the small head with a washer built in for clearance under the pipe. A regular bolt with a 17 mm head works, just a bit tighter to get a wrench on.
