Carburetor Rebuild Kits

Welcome to our Harley Carburetor Rebuild Kits collection — your trusted source for quality rebuild kits and parts designed to restore, maintain, or upgrade the carburetor systems on your Harley-Davidson motorcycle. Whether you ride a vintage Sportster, Softail, Dyna, or any custom carb-equipped build, a rebuild kit is essential to ensure reliable engine performance, smooth throttle response, and proper fuel-air mixture.

Why Rebuild Your Harley Carburetor

• Restore Performance & Reliability. Over time, gaskets, seals, float valves, and jets deteriorate or get clogged — leading to leaks, poor idling, uneven throttle response, fuel starvation or flooding. A rebuild kit replaces these wear-items to bring your carb back to like-new condition.

• Ensure Proper Air–Fuel Mixture. Worn, cracked, or hardened seals and old jets can disrupt the carb’s ability to meter fuel correctly. A rebuild helps restore precise air/fuel metering, which improves combustion, throttle smoothness, and overall ride quality.

• Prevent Fuel Leaks & Carb Failure. Fuel leaks from degraded float valves or bad gaskets are common with aged carbs. Refreshing these components reduces the risk of leaks, flooding, or carb failure — which can lead to engine damage or unreliable starts.

• Extend Carburetor Life. Instead of replacing the entire carburetor, a rebuild kit gives you an affordable, effective way to maintain your existing unit — saving money while keeping your bike’s original setup intact.

• Ideal for Vintage, High-Mileage, or Project Bikes. Older Harleys or bikes that have been sitting for years benefit most from rebuild kits — addressing issues like hardened gaskets, dried jets, or float-valve wear that accumulate with age.
