My 83 gl 1100 is smoking when it heats up. The bike doesent over heat. It has sat for about 5 years.The mechinic said that is was proubly a bottom end problem and I will need a new engine. I do not now anything about the history of this bike. If any one has any sugestions let me know.



Got the bike the carbs were gunked ran sea foam and tried to clean them up.The floats were sticking and caused the engine to Hydro lock.Took it to a mechanic for a profesional job. That is where iam at right now with this thing. Thank you.

Check the crankcase vent, it is the tube from the left rear of the engine going to the air cleaner. It may be clogged causing excess crankcase pressure. Other than that Pour a bottle of Marvel Mystery oil or about 1/2 can of seafoam in the oil and take it for a 100 to 200 mile ride and change the oil when you get back. The engine may just need a good cleaning out.

Hope you get it going soon. I had an 81 that had been sitting for a long time and it smoked for a few hundred miles, I did a Seafoam treatment to it just to see if it would work and it finally did stop smoking. I have no idea if it was the Seafoam or just running it hard that cleared it up.

Mine sat for 3 years, after I got the carbs sorted it used to smoke when warm, white smoke. Done the seafoam in the oil for about 200 miles then dropped the oil and changed filter, no sign of smoke for the last 4000 miles, not even on start up after laying on the side stand. Seafoam can lube the top end when you put it in the gas, maybe the rings need to be freed, enough seafoam should do the job. Worth investing in a bottle of the magic foam and putting some miles on the clock.

Good luck
