I'm watching this thread too. Hoping Doebeck still is. TQ I'm thinking I read somewhere the HD OEM 02 sensor threads are the same M18x1.5 threads as the wide band Doebeck provides. (I know for sure that's what they are on my 1988 Chevy truck) Anybody find this out yet ?
Thanks, I thought that was the threads on them cause I heard a guy talking bout plugging his sensor holes one time with a M18x1.5 muffler plug.
The AF gauge looks good. I'm ignorant on fairing Ultras and such, what used to be in the place the AF is now ?
