I was washing my bike this morning and noticed my rear cylinder exhaust flange is missing one nut and the other was about to come off. Probably explains why I was noticing a slight loss in power and slight exhaust leak sound. Anyways I don't have the HD part number book/pdf and I'm just wanting to head down to the local auto parts store to get the nut. Can anyone tell me what size nut goes on the exhaust flange bolts up by the head?

It's part number 35 in this bike bandit schematic. The bike bandit part number is 467658 (1678478-001) but it doesn't tell me the size of the nut (ex: 5/8-18 flange nut).

Any help is much appreciated!

 

Edit - a member on XLF posted it for me. Anyone who might need the size for future reference here it is 5/16-24 Flange Nut (HD Part #7593).

 

Been there, u won't find it at the auto parts stores, I went to 5 before deciding to go to the dealer, I wasted more time n money then I would have saved, they are not bad priced.

 

Aircraft-style "Jet" or "Kay" nuts are ideal for this application. Corrosion resistant, self-locking, reduced hex (twelve point) for access, and strong.

 

Yup I tried the local auto parts store and Lowe's. Finest thread in 5/16 either of them carried was an 5/16-18. Thankfully the HD store was open. Nut cost 50 cents.
