Buying Guide and FAQs

Buying Guide: Factors to Consider When Choosing Harley Bike Carburetor Kits

  • Compatibility: Ensure the kit fits your Harley's model (e.g., Big Twin Evo 1993-1999, Twin Cam 1999-2005, XL Sportster 1991-2003, Shovelhead 1966-1978) and engine size (e.g., 80" to 100"). Use the vehicle selector for year-specific matches to avoid throttle or manifold issues.
  • Type of Use: For street cruising or touring, opt for Super E kits with 1-7/8" throat for smooth response; high-performance or race builds benefit from HSR 42/45/48 or Super G for maximum power and acceleration in demanding conditions.
  • Components and Upgrades: Select kits with carbs, manifolds, air cleaners, cables, and hardware; upgrade to polished or black finishes for style. Focus on smoothbore designs, adjustable accelerator pumps, and high-flow filters for better throttle and mileage.
  • Brand and Quality: Choose S&S Cycle for Super E/G kits with proven throttle response or Mikuni for HSR series with race-custom options. Prioritize made-in-USA/Japan quality with chrome/natural/polished finishes for durability and reliability.
  • Installation and Cost: Most kits are bolt-on with included hardware for easy DIY setup; prices range from $499.95 for standard carbs to $955.95 for total kits—factor in sales (up to 10% off) and free shipping over $99 for value.

Frequently Asked Questions (FAQs)

  1. What Harley models do these carburetor kits support? Kits support Big Twin (1993-1999), Twin Cam (1999-2005), XL Sportster (1991-2003), Shovelhead (1966-1978), and more—use the year/make/model filter for exact compatibility, including manifold inclusions.
  2. How do Super E/G carbs improve performance? They offer excellent throttle response, power gains, and mileage with 1-7/8" throat and 1-9/16" venturi, ideal for engines up to 100-cubic-inch.
  3. What is typically included in a kit? Most include carbs, manifolds, air cleaners (e.g., K&N), choke cables, hardware, and instructions; check details for polished finishes or race customs.
  4. Are these kits suitable for custom engines? Yes, HSR 48mm kits are designed for custom/race engines with high-flow features and tuning jets included.
  5. What if a kit doesn't fit my Harley? Verify engine size, carb type (Super E/G, HSR), and manifold requirements before buying. Our returns policy allows exchanges or refunds if it doesn't match.
  6. Can I find related air and fuel parts? Yes—explore jets, rebuild kits, or air cleaners in the Harley air and fuel category to complement your carb upgrade for optimal performance.

Big Power, Nice Sound!

Picked up a Pro Circuit pipe and silencer for my YZ125 it’s a game changer. The power feels way better and the sound is awesome.

Helps keep cool, works great!

Bought the dual pass Allstar radiator for my build, and it’s been solid. Keeps the engine running cool even on the hottest days no complaints here!
