The fact we have no info to go on makes it hard to help u. Most harley shops get 1 hour 80$ to set up a Carb maybe this would be the way to go...

it is a 2003 100th aniversary edition with a stock carb. It is running real rich, coating the tail pipes in soot, and leaving a nice odor of fuel coming out of the exhaust. It has an 88 CI motor, with no additional work done to it. What other information would you like?

1st thing to do is pull your plugs to see if they are black and sooty. If so, either your pilot jet and/or your main jet is too large. If you don't know how to tune your carburetor, take it to a good Indy and let him re-jet your bike.

When you start your bike using the enrichener **** when it's cold, do you push the **** back in after a 1/2 mile to a mile? When was the air filter changed last? Visit nightrider.com and look up the carb tuneup.
