Frequently Asked Questions

Will this fit my Harley with a Mikunni or Dellorto carb?

No — this jet is only compatible with Keihin BH carburetors. Different carb types require different jet designs.

What does the #52 specification mean?

#52 refers to the orifice size of the pilot jet, which controls idle and low-throttle fuel mixture. Size #52 is the stock specification for most Keihin BH applications.

How do I know if I need to change my pilot jet?

Pilot jets are typically swapped when the bike runs too rich or too lean at idle and low RPM. A smaller number leans out idle, a larger number richens it.

Is installation difficult?

Pilot jets are accessible from the carburetor bowl. Remove the bowl, unscrew the old jet, and screw in the new one — basic hand tools only.
