    Engine Smoking

    Is it normal for an engine to lightly smoke from all over when it has sat a long time? I just changed the oil and ran it for about 20 min and it lightly smoked and had a bit of a burning oil smell. No leaks and the smoke was so light I couldnt pinpoint where it was coming from. Looked to be generalized to the whole motor. I know this motor is air cooled so I thought it might be cause it was sitting still while running for a long period of time.

    Probably just Ohio dust- when weather is good, take it for a ride to clean it and then doublecheck oil filter area for leak.

      ok cool. I did just change the oil and I saw no leaks but there probably is a fair amount of dust on the motor.

        Never let the engine run more than a few minutes without air flowing over it. You will over heat it. Not sure if you did this but don't. Also, don't run your bike in the driveway during the winter. Either ride the bike or leave it alone. Short winter run cycles result in condensation accumulation in the engine and exhaust pipes, and no good comes from that.

        Sometimes when changing the oil some drips on the exhaust pipes or similar, and when running the bike thereafter the oil will burn off.

        Needless to say, you should make sure the engine is oil tight and not leaking anywhere. Valve covers commonly leak, but that's not necessarily a bad thing if that means someone has adjusted the valves like they should. There is more to maintenance than just changing the oil.

          I did take the bike for a short ride but I probably did let it idle too long. Wanted to get the oil warmed up for an oil change. Thanks

            The same thing happened to mine when I fired it up for the first time. At first I thought it was some electrical wire or component getting too hot. But eventually I figured it was the bike having not been run in at least a decade and therefore having a light coat of oil and garage dust all over the engine. Next time I let it idle for any period (which will be to change the oil), I'll definitely have a fan or two on it. (And yes, it'll get a good scrub-down in the spring...)
