Specs At A Glance

Good To Know

Q: How do I know if my float needs replacing? A: A float that has absorbed fuel will sit low, causing rich running, hard starting, or fuel overflow from the carburetor bowl. Comparing float height against the service spec during a rebuild confirms whether replacement is needed.

Q: Can I replace just the float without other carburetor parts? A: Yes, the float can be swapped on its own, though many riders replace the needle valve and gaskets at the same time while the carburetor is open. Inspect adjoining parts for wear before reassembly.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
