    1100 Zxi.. fuel mixture coming from the exhaust

    I am helping a buddy work on his '96 1100 zxi... he cleaned out the carbs and said they looked good. Compression is good as well. When started on the trailer, there is a pretty significant amount of fuel/oil mix coming out of the exhaust. He bought it second hand, so I don't really know much about it. Seems to run good, but I know it shouldn't have that much fuel coming out the back. Any ideas what to check first?

    The carbs really need to be rebuilt especially if they were taken apart. If you have raw fuel coming out of the back, you probably have a stuck needle. don't run bad gas through those carbs either because it will wipe out the needle. I learned that the hard way

    Keep in mind that, on the trailer, there is no load on the engine and it will run rich. These things also smoke a lot when idling, too.

    Make sure to inspect the oil lines for cracking. They should probably be replaced.

    Steve is right. They smoke a lot out of the water starting from cold. Best check is right after a good ride when you pull out to see what its like then.
