Default Black Smoke-No Start 2005 Bandit 1200

My 2005 Bandit has been running fine for it's 3000 miles although it sits quite a bit. When going out for a ride a couple of weeks ago the bike ran out of gas leaving the driveway. When I switched the fuel valve to Res, white/blue smoke came billowing out of the exhaust pipe and the bike refused to start and stay running.
After sitting a few weeks, I then took off the carbs (thinking the jets were plugged from sitting so often) and blew out the jets, pulled the fuel valve from the tank - everything looked good. I drained the tank and added a couple of fresh gallons of gas, reassembled the carbs, checked the plugs (looked a bit on the black side), checked the air filter (looked a little on the wet side) and tried to start again. This time, black smoke came billowing out and the bike would not stay running. As I let it sit after trying to get it started, fluid came pouring out of the bottom of the air cleaner box. The oil level looks a little high, so I don't know what to think.
Anyone have any insight or advise.
Thanks

Sounds like the float level got goofed up when you re-assembled the carbs. It's a real pain to take that rack off again, but you're going to have to do it to get the carbs straightened out.

Since gas is lighter than water most likely you had some at the bottom of the tank, and when you switched to reserve it got sucked into the carbs and caused the white smoke (condensation, steam). Black smoke means over-rich, from the float level (and the gas running out of the airbox).

Good luck and get a manual that shows you how to set the floats.

Your float valves may be leaking as well, fouling the plugs and creating more black smoke.

Thanks for the feedback, this is very helpful.
I did not adjust or touch the floats, but just pulled the 3 jets off under the carb (in the float bowl area) and blew them out with compressed air. I guess I'll have to remove and ensure that one of the floats is not sticking. Is that common after removing the bowls?

Black smoke is excess fuel/insufficient combustion air. Either the Forced Draft Blowers and/or Induced Draft Blowers are set too low or your Fuel Valve is open too far. Other possibilitys are low atomizing steam or air pressure or a clogged, loose or oversized sprayer plate in the burner gun assembly. Varify 20% excess air with your F/A set points and fan bias, run an O2, CO and combustables check and try a different oil gun. Ensure a minimum 20psi atomizing steam differential.

If that don't do it, remove the carbureter bank, soak it in warm salt water for three days out of direct sunlight then discard the motorcycle.

What about the check valves? You didn't tell him about the water hammer steam check valves! You are a slacker seam room dude. No wonder we never had any hot water.

HA! what are you talking about? we always had plenty of hot water LOL. Besides, check valves won't cause black smoke. A failed steam trap on the atomizing steam line to the HP drain main might, that could over time allow condensate to mix with the steam and make the fires sputter. Trouble is I used to set my mystery meat sandwichs on top of it to keep them warm when I was on 8 & 8 so I'd know right off 'cause my lunch would be cold.

Did you know our High Pressure Drains on the Browneye were 150 psi? in the civillian world anything over 15 psi main steam is considered high pressure....

So, I take it that your boilers at Boeing aren't running 800+ superheat?

Nah, 125 saturated and hot water boilers mostly. Easy money

Remember the movies in boot camp about superheated steam? But that one pailed in comparison to the flight deck camera on the Forrestfire. I liked the part where the Chief runs into the conflagration with a 20 lb. Co2 fire bottle, a split second later a 500 lb bomb cooks off and , hey? Where'd the Chief go?

Scratch one E7.
