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)
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
