- Carefully replace the old gaskets, seals, float, needle valve, and other components with the new parts from the kit.

Troubleshooting & FAQ
How do I know if this kit fits my specific engine?
Your primary check is the Compatibility Table in this listing. Match your engine's model, horsepower, and year range. If any details conflict, or if you are unsure, contact us with your engine's full model and serial number before purchasing.
What are the signs of a failing carburetor that this kit can fix?
Common symptoms include difficulty starting, rough idling, stalling, poor acceleration, hesitation, or black smoke from the exhaust. This kit replaces the most common wear items that cause these issues.
Is this kit for a single carburetor or a full set?
This kit contains the parts to rebuild one (1) carburetor. Since most Yamaha V4 and V6 engines have multiple carburetors, you will need to purchase one kit for each carburetor you intend to service.
How often should a carburetor be rebuilt?
There is no fixed interval. It depends on fuel quality, usage hours, and storage conditions (especially with ethanol-blended fuels). A rebuild is typically done when performance issues arise, or as preventative maintenance every few seasons.
OEM vs. Aftermarket?
This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
Shipping speed & cost
We ship worldwide quickly—typical transit 5–15 days. Standard shipping is free; expedited options appear at checkout where available.
