Frequently Asked Questions (FAQs)

1. Are all carburetor rebuild kits the same?

No, carburetor rebuild kits do not all contain the same components. The contents of a rebuild kit may vary depending on the specific carburetor model and manufacturer.

2. How do I know what carb rebuild kit to get?

The best way to determine the correct carburetor rebuild kit is by using the carburetor number. Most carburetors have an identification number stamped directly on the carburetor or on a tag attached to one of the carb body screws. Matching this number with the appropriate rebuild kit ensures you get the right components for your carburetor.

3. Is it cheaper to rebuild a carburetor?

Yes, rebuilding a carburetor is a more affordable option compared to purchasing a new one. A rebuilt carburetor typically costs between $200 to $500. However, it's important to note that a rebuilt carburetor may not be as efficient or last as long as a brand new one.

4. How do you tune a carburetor after rebuilding?

After rebuilding a carburetor, it is recommended to set it to the factory adjustment. This involves adjusting the idle mixture screws to 1.5-2 turns out and the idle speed screw to 1-1.5 turns in. Additionally, warming up the engine to its running temperature is crucial for proper air and fuel mixtures.

5. Do you have to tune a brand new carburetor?

While most aftermarket carburetors are calibrated and tested at the factory for ready-to-run operation, some settings may be affected during shipping. It is advisable to perform some tuning and adjustments to ensure the new carburetor is operating at its optimum performance and delivering maximum results.

6. Do you have to sync carbs after rebuild?

Yes, after cleaning, repairing, and reassembling motorcycle carburetors, it is necessary to balance and synchronize them. This ensures that each carburetor is providing an equal air-fuel mixture to the engine for smooth and efficient performance.
