Question about Harley Davidson Motorcycles
Harley Davidson 2008 Heritage. Poor fuel economy.
Hi Brian, there is always a trade off when seeking more performance and usually its fuel milage especially on heavier bikes. That being said going from 42 mpg to 27mpg is a bit excessive. Was there a significant change for the better in performance? Did they go larger injectors or bigger jets? Dialing those down a bit would increase mpg. Also was any remaping involved? I would go back to the shop and ask them if loosing half of your mpg is normal for a stage one kit. Good luck
