Motorcycle Repair: 1999 Heritage Softail Classic, heritage softail, dyna jet

Question
QUESTION: I'm only getting 20 MPG and I think it could be a choke adjustment, when I throttle it kind of feels like the choke is still on (dogging a little). Also after the starter was replaced I have a bad vibration, I can feel it especially on the highway, my feet on the foot rest shake like crazy.

ANSWER: There is no adjustment to the choke. Pull your plugs and let me know what color they are

QUESTION: Black - How about the vibration?
Thank you very much Mike,

Answer
Since your plugs are black you are either running to rich or you have bad coil or plug wires. I would test the coil adn plug wires. If they are good then you need to rejett the carb. I would add a dyna-jet kit. It will give you the proper jetting.
On the vibration, the starter wouldnt cause a vibration. I would check your front tire for wear and check the motor mounts for tightness
Good luck and happy riding
Mike
