Frequently Asked Questions

Do I need to machine the cylinders or rebalance the crank?

No — this is a true bolt-on kit. Pistons and cylinders install without machining, and internal engine components don't need rebalancing.

Will this kit work with my stock heads and pushrods?

Yes. The kit uses your stock heads, pushrods, and fuel system — only the pistons, cylinders, and cam are replaced.

What kind of power gains should I expect?

With stock intake and exhaust, you'll see modest gains. Pairing the kit with S&S intake and exhaust can deliver up to 85 horsepower.

Is this compatible with the XR1200?

No — this kit is not compatible with XR1200 models. It fits 2000-2021 standard Sportster models only.

Can I use this for street riding, or is it Hooligan-racing only?

The kit is designed for both Hooligan flat-track racing and street/strip use. It's street-legal in stock form with OEM intake and exhaust.
