Frequently Asked Questions

What jets are included in this kit?

Main jets, pilot jets, accelerator pump jets, and slide needles — a complete range for tuning the HSR carburetor across all RPM ranges.

Does this fit my Harley or Indian with a Mikuni HSR?

Yes — this kit works on any V-twin motorcycle running a Mikuni HSR carburetor, including Harley and Indian models that have been upgraded to HSR carbs.

Will I need any tools to install these jets?

You'll need basic tools to remove and reinstall jets in the carburetor — a jet removal tool and screwdrivers. Carburetor removal may be required depending on your bike.

Do I need to rejet if I add an exhaust or air filter?

Possibly. Aftermarket exhaust and intake modifications often require rejetting to maintain proper fuel delivery. This kit gives you the jets to dial it in.
