Frequently Asked Questions

Does this kit include everything I need to install it?

The kit includes carburetor, manifold, flange, filter, and seals. You'll need to source manifold clamps separately, and 1984-1989 bikes need cables from a 1990-1995 model.

Will this fit my Twin Cam Touring?

Yes — any Twin Cam model in the 1999 range and earlier will accept this Total Kit.

How much horsepower will this support?

The high-flow filter and 42mm carb are calibrated to support up to 100 horsepower without restriction.

Do I need a tuner or fuel management system with this kit?

The kit is designed as a direct bolt-on solution. A tuner or fuel controller may optimize idle and transitions, but is not required.

Really couldn't stand the look of the dangling adjuster. Screw the old one out, transfer the spring, screw this one in and you're done. Also, you can still adjust the idle speed while sitting in the seat (on my 94 WG). Highly recommended.

Very nice piece. You do need to remove the switch housing on that side, drill out the existing hole and tap it. (Tap not included but a standard size). Works precisely as it should and a big improvement over the stock set up. Oh and it looks great too.

Solves the dangly speedometer cable effect of the stock idle screw, easily modified. I put a chrome dice on the end of mine and it looks trick.
