Title: c90 exhaust studs
Post by: bullet350 on October 03, 2008, 06:54:12 PM

evening all,


does any one know how far into the head the exhaust studs go on a c90?

needless to say both studs sheered off when a spanner was put anywhere near them, i just need to know how deep to drill a hole for the new studs.

the old exhaust split clean across, leaving just a two inch stub out of the head. the bike ran exactly the same without the silencer, and wasn't all that loud!

I'm pretty sure it's around 16-17mm.
