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.


Answer by  Amber40 (24961)

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.
