Motorcycle Repair: 1980 Honda CB650 help, fuel mixture, gray smoke


Question
I recently purchased this a 1980 Honda CB650 and cleaned the carbs out. well I did what the shop manual said to do with the pilot screws and back them out 1 - 1/2 turns out and the bike starts and runs great other than the fact that white smoke pours out of the exhaust and around the motor area not sure where yet though. possibly the carbs? I was told that it was the carbs need adjusted more and its getting too much oil and that causes white smoke. and I heard blue smoke is fuel. but I'm getting white smoke. it never did this before so please help me. thank you very much.

Answer
Joe,

white smoke is usually caused by condensation
burning out of the pipes or in the case
of a liquid cooled bike, antifreeze leaking
into the engine through a gasket or cracked
cylinder head.

-The only things I can suggest in your case is
make sure your oil level is not too high. Make sure
the oil is not contaminated with moisture.
-Check the air filter and engine breather for
obstructions also.
Generally blue smoke is oil burning,
white smoke is moisture or antifreeze
and gray smoke is a lean fuel mixture
or overheated engine.
Carb problems would likely make black smoke.
-i hope it isn't a wiring problem and burning
wires?
