Street Bike Carburertor Main Jets

Buying Guide and FAQs

Buying Guide: Factors to Consider When Choosing Street Bike Carburetor Main Jets

• Compatibility: Match jets to your bike's make (e.g., Suzuki GSX-R, Honda CBR, Kawasaki ZX, Yamaha R-series) and carburetor type (e.g., Mikuni VM16, HS40, HSR42/45/48, RS, TM, VM29/33 Smoothbores). Use the vehicle selector for year-specific fits to ensure precise metering without performance issues.
• Type of Use: For high-RPM street or track riding, select main jets (sizes 100-210) for optimized fuel delivery; low-speed/idle tuning benefits from pilot jets (sizes 15-60) in multi-carb setups for smooth response in urban or touring conditions.
• Components and Upgrades: Choose 4-packs with brass construction, slotted heads for easy adjustment, and OEM-quality specs. Focus on ethanol-resistant materials and precise sizing for tuning fuel mixture, throttle response, and engine efficiency.
• Brand and Quality: Opt for Mikuni for premium, Japan-made jets or EBC for compatible alternatives. Prioritize brass slotted designs for durability, accurate flow, and longevity in modern fuels.
• Installation and Cost: Jets are simple to swap with basic tools for DIY tuning; sold in 4-packs for convenience. Prices are $5.20 per pack—consider bulk for multiple sizes and free shipping over $99 for value.
