Hello riders and fixers,
Rebuilt carbs on ‘81 750k. Idle is good revs hang somewhat not real bad. Its rideable 65 has 5000 to 5500 rpms. I was waiting on someone with the bike on idle. Moving the black idle adjustment knob along with moving the pilot screws trying to get it just right. I noticed white smoke coming from the number two exhaust pipe. Lean rich or something else? On Saturday I will take the plugs out to take a look at

Black smoke = rich.
White smoke = water/steam.
Are you getting condensation in that pipe, maybe? Maybe look for holes in that exhaust from the header all the way to the muffler.
 
Ok, thanks. I have had those pipes off when I first purchased the bike to use steel wool to buff them up. Maybe not seated right.
Thanks again
