What parts and materials are included in the rebuild kit?

AHL’s kit contains the wearable small parts typically replaced during a carburetor rebuild, made to withstand fuel exposure and repeated use. The kit emphasizes durable copper components for key fittings plus aftermarket-quality rubber and metal seals. It’s intended to supply everything necessary for routine rebuilds, though carburetor body damage or severe wear may still require additional parts.

• Main and pilot jets, float needles, and seats
• O-rings, seals and gaskets made for fuel resistance
• Copper fittings and small hardware components
• Assorted screws, springs and clips to reinstall assemblies

How will installing this kit affect performance and maintenance?

Replacing worn jets, needle valves and seals helps restore predictable fuel metering and reduce leaks or erratic idling associated with aged carburetors. The kit is a cost-effective way to address common wear items without buying a new carburetor. Results depend on correct installation and any underlying mechanical issues beyond consumable parts.

• Improves fuel sealing and reduces float-related fuel overflow
• Helps restore steady idle and throttle response when worn parts are replaced
• Lengthens service intervals when installed correctly
• Requires careful inspection of the carburetor body and float bowl for best outcome

What should I check before buying or installing this kit?

Confirm the OEM part number and visually compare supplied pieces to your existing carburetor components. Inspect the carburetor housing, float bowl and slide for corrosion, warping or damage that a rebuild kit won’t fix. If uncertain, contact the seller with your bike year, model and carburetor photos to verify fitment.

• Match OEM PART NUMBER: 16100-MEN-A02
• Compare shape, size and component layout to your carburetor
• Check for carb body damage that requires replacement instead of rebuild
• Contact seller for fitment questions before purchase
