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.
Frequently Asked Questions (FAQs)
- What street bike models do these carburetor main jets support? Jets fit models with Mikuni carbs like Suzuki GSX-R, Honda CBR, Kawasaki ZX, and Yamaha R-series—use the year/make/model filter for exact compatibility, especially if stock Mikuni-equipped.
- Main jets vs. pilot jets: What's the difference? Main jets (e.g., sizes 100-210) control high-RPM fuel; pilot jets (e.g., sizes 15-60) handle idle/low-speed for smooth acceleration and response.
- How do brass jets improve tuning? Slotted brass construction allows easy adjustment, precise metering, and resistance to modern fuels, optimizing mixture for better throttle and performance.
- Are these jets sold individually? No, available in 4-packs for convenience in tuning multiple carbs or testing sizes.
- What if a jet size doesn't match my bike? Verify carb type and size before buying. Our returns policy allows exchanges or refunds if it doesn't fit.
- Can I find related air and fuel parts? Yes—explore rebuild kits, needles, or full carbs in the street bike air and fuel category to complement your jet upgrade for complete tuning.
