How do I make an adjustment to the air fuel mixture on a Harley?

Answer by  Amber40 (24961)

To change the air/fuel ratio on a carbureted engine you need to change the size of the jets in the carburetor. For a leaner mixture you need to swap in smaller jets to restrict fuel flow, bigger jets for a richer mixture. Experiment with sizes to get the perfect mix.

If it is a carbuerated bike then to add or reduce fuel you need to change out the jets in the carb. On a fuel injected bike you will need to adjust settings in the ecu to modify fuel delivery and reduce the amount of fuel.

Unless you have a fuel injected Harley then you have to pull off the carburetor and re-jet it until the air/fuel ratio is correct.

Depends on the type of carburator you have. A fuel injection all you need to to is pull the carb. off and reject thee air till you have it right.

you can adjust the air fuel mixture in the croprator of that motorbike. that croprator located in below the fuel tank. you can adjust the air fuel mixture in that place. if you don't know about the croprator, you just ask workshop and than adjust the air fuel mixture in the croprator
