Harley Davidson Carburetors FAQ's

What is the most popular carburetor for a Harley?
People have been tinking with Harleys since the moment the first one rolled out of the factory. That means different builders working on different bikes in different eras have found a wide variety of options for sending fuel and air into their carbureted Harleys. With that said, a few options have emerged over the years as particularly popular: The S&S Super E carburetor is probably the most well-known aftermarket carb for Harley-Davidsons. It's reliable, easy to tune, and a huge performance upgrade over many older stock carbs. The Mikuni HSR is another fantastic and very popular choice known for its great throttle response.

How do I know if my Harley's carburetor needs to be rebuilt?
Signs your carb needs a rebuild include hard starting, a rough idle, or a "bog" (hesitation) when you twist the throttle. If the bike has been sitting for a long time, the tiny jets inside are likely clogged with old gas, and a rebuild kit with new gaskets, O-rings, and jets will go a long way.

What's the difference between a CV carb and a slide carb?
A CV (Constant Velocity) carb, like the stock Keihin, has a vacuum-operated slide. It's smooth, efficient, and very forgiving. A mechanical slide (or "flatslide") carb, like a Mikuni or S&S, has a slide that is directly connected to your throttle cable. This gives you instant, snappy throttle response, which is why they're a popular performance upgrade.

Can I tune my Harley's carburetor myself?
You sure can! Basic carb tuning mainly involves three things: the idle speed screw (for how fast it idles), the air/fuel mixture screw (for the idle), and the jets (for midrange and wide-open throttle). Swapping jets is pretty simple, and it's a "must-do" after you add a new exhaust or air cleaner.

When should I upgrade my carburetor?
You should upgrade your carburetor when you do other performance mods, like a cam, high-flow exhaust, or headwork. The stock carb can't always provide enough fuel and air for a "built" motor. A performance carb like an S&S Super E or Mikuni HSR is designed to deliver the flow you need for those big power gains.
