Buying Guide and FAQs
Buying Guide: Factors to Consider When Choosing Harley Bike Carburetor Main Jets
- Compatibility: Ensure jets fit your Harley's carburetor type (e.g., Keihin CV, S&S Super E/G, Mikuni HSR42/45/48, HS40) and model (e.g., Big Twin 1988-2006, Sportster, Evo, Twin Cam). Use the vehicle selector for year-specific matches to avoid tuning or flow issues.
- Type of Use: For stock or performance tuning, select main jets (sizes 160-220, .062"-.080") for high-RPM fuel; intermediate jets (.0295"-.033") suit low-range adjustments; assortment kits are ideal for dyno testing or altitude changes in street or touring conditions.
- Components and Upgrades: Choose individual jets, 5-packs, or assortment kits; upgrade to extension kits for air bubble prevention. Focus on precision-machined brass for accurate metering and improved throttle response/power.
- Brand and Quality: Opt for S&S Cycle for Super E/G jets, EBC for Keihin assortment kits, MIKUNI for HSR extensions, CYCLE CRAFT for brass main jets, or YOST PERFORMANCE for 195-220 kits. Prioritize Japan/USA-made brass for durability and consistent flow.
- Installation and Cost: Jets are simple swaps for DIY tuning; kits include multiple sizes for convenience. Prices range from $4.79 for 2-packs to $64.67 for assortments—factor in sales (up to 10% off) and free shipping over $99 for value.
