Topic: Question: Bolts/Screws for exhaust header

[wilson889]

Hey, I didnt know where to post this. I need measurements for the exhaust/header bolts/studs/screws that came stock with these bikes.. Anybody out there know? My bike's header was replaced with an aftermarket one, and they are black anodized , and they dont seem to fit all the way in, and are all starting to rust

Oh geez I did it again... its a 1975 cb750K looks like a 4-1 mac header but was told it was a manufactured yosh (not hand bent)

I'd say you need bolts a bit longer that you have. Take one with you to the store and compare it against one a bit longer.

I used M8x25 allen head bolts to hold my exhaust spigots on. (fastenal part# M42580025A20000)
