Frequently Asked Questions

What does the richest taper mean?

Richest designation provides the most fuel delivery in the mid-range throttle position, compensating for lean running or high-altitude riding.

Will this work in my HSR45 carb?

Yes — this needle is a direct replacement for any Mikuni HSR45 carburetor that requires the richest taper specification.

Can I swap between different taper needles?

Yes. Different Mikuni needle tapers control fuel mixture at mid-range throttle. Verify your current needle part number before ordering if you're unsure which taper you need.
