Just installed Supertrapp 2:1 on 01 FLSTC. Plogged Oxygen sensor hole with supplied plugs. Notice there are no gaskets supplied for these plugs. Are they requirend??

let bike idle for 5 minutes and noticed smoke coming f4rom ocygen sensor bung plugs. Is this just anti seize burning off??

No gaskets required and yes it is most likely burnoff if there is no pressure from the gas. If there is pressure to the gas (hear & feel) it's a leak.
