Major Smoke Issue 85 GL1200 Aspencade

Postby kwright12123 » Wed Jun 01, 2011 9:24 pm



Bike sat all winter, checked the oil and seemed low so I added (in error) four quarts of 30 weight regular motor oil. Bike started fine and ran okay then began smoking terribly out of both exhausts. Shut it down and asked a friend who told me I most likely over filled the oil and used the wrong type. I drained all the oil and changed the filter and replaced with 10w40 Motorcycle oil. I've ruun it a couple of times since only at idle and for less than three miles and the smoke continues. My friend said he thoought after I changed the oil the bad stuff would burn off. Motor make no knocking noise and seems to run fine just smokes alot. Anyone have any idea what may be the problem?

Thanks

What color is the smoke? Is it oil smoke or antifreeze? If it's oil and it got in the exhaust it will take awhile to burn it out. Other poss is that the rings are stuck. Put in some seafoam, in the gas and crankcase. Run the engine till she gets warm then hold the rpm's up around 1,800-2,000 rpm's for a few min's and see if the smoke starts to back off. If she smokes bad I wouldn't take her on the road.. "safety first".. Put a fan in front of the rad to help her from over heating!
Let me know what happens!
How many times do I have to tell ya,,, The right tool for the right job!

It is oil smoke I believe I checked the antifreeze and seems to be fine as far as color. No oil in with it. I will try adding some seafoam and hopefully that will clear it up. Thanks for the info.

Pull the air filter out and check the intake manifold for evidence of oil.

The gearbox/engine breather routes to the airbox (so that all hydrocarbon fumes get passed through the engine and burnt) so if you overfilled the engine there is a good chance that oil will have got blown into the airbox assembly and the inlet manifold. It will take a while to clear that out and burn it all off (you will have a lot of smoke until you do). I would suggest removing the air filter, make sure it is not wet with oil, then I would be looking for a way to clean up the inlet manifold to remove what ever oil is in there. You can damage an engine by running it with too much oil, but it doesn't sound like you ran yours for very long, so I really doubt you damaged anything inside the engine, I think you just have a lot of oil inside the admission system (Carbs and inlet manifold) that needs to be cleaned out, then normal service will be resumed.
