What fuel management system do I use for a Harley-Davidson?

Well, the simple answer in California is only one that is CARB and EPA compliant because no vendor will ship it to you.

We could cover the reasons why but if you have been on the forums and other sites sell exhausts and other emissions-related components then you would know that California some of the toughest restrictions and regulations regarding the changing of emissions components.

Also, numerous customers are reporting that Harley-Davidson is not honoring warranty work or at least making it very difficult when needing warranty repairs.

For a really good and in-depth look at fuel management systems, I would watch this video https://www.youtube.com/watch?v=xNEURz3I3kc from Doc Harley at Low Country Harley-Davidson.

Listen really carefully to his speech about the warranty.

Also, please be aware that in California there is a modified exhaust law that requires a citation for any violation. In many cases may also result in a trip to the Bureau of Automotive Repair referee to confirm you have fixed the exhaust.
