Common questions
What does the #160 jet size indicate?
The #160 jet size controls the fuel flow through the main circuit, primarily affecting the mixture at cruising and higher throttle positions. A higher number like #160 provides a richer fuel mixture.
When would I need to use a #160 main jet?
You might need a #160 main jet if you've installed a high-flow air filter, an aftermarket exhaust, or if you're riding at higher altitudes, all of which can require a richer fuel mixture for optimal performance.

These are genuine Mikuni large round main jets and are compatible with Mikuni carburetors found on V-twin motorcycles, including Harley-Davidson. Always verify your specific carb model uses large round jets.
