White smoke comming from one side of mufflers. Does this mean head gasket on those 2 heads? its an old goldwing I thought it was air cooled, maybe not. Not my bike, just got a call from a friend. Thx Guys, B

White smoke is an indication of water in the exhaust. This can be from condensation in the muffler, but that type of smoke usually dissipates after a minute or two of running. Constant, thick white smoke is usually a sign of water leakage into the combustion chamber(s), either via a blown head gasket, cracked head, or cracked block.

What is year--make--model?
Are you losing coolant? The white smoke may be coolant in the combustion cylinder, possibly caused by a head gasket problem. If head gasket problem, fix that first.

With idle issues, clean/check anything that has to do with idle air system. Any applicable trouble codes?

check and test for blown head gasket

WHITE SMOKE COMING OUT OF EXHAUST TAIL PIPE OR OVERHEATING IS BLOWN HEAD GASKET.

white smoke is probably steam,which could mean a blown head gasket, cracked head or other expensive problems :( I would watch the coolant level closely, it could also just be condensation collecting in the muffler.

White smoke....Means a Blown Head gasket.. Now its not bad enough to stop the vehicle from running but its bad enough, to blow out white smoke..now sooner or later it will stop completly, but you dont want to warp the cylinder heads too bad, then you will have to replace them also, so you might want to fix this problem as soon as possible...and the muffler keeps going bad, becasue it is filling up with coolant/ or too much water, which it is not designed to do..You also maybe doing damage to your cat. converters also...so be careful....And Goodluck, and keep me posted...

sound like your going through antifreeze??? am I correct?
