Moturo Carburetor Repair Kit for Yamaha YZ 125 99-00

The Moturo carburetor repair kit for your Yamaha YZ 125 99-00 — the standard overhaul for the 125cc two-stroke after high mileage or extended periods of inactivity. Includes jets, float needle valve, jet needle, and gaskets, ready for installation.

This repair kit replaces the wear parts in the carburetor of your YZ 125 (model years 1999 to 2000). It contains O-rings, a float needle valve, jets, a jet needle, and other small parts for a complete carburetor overhaul.

Typical symptoms before replacement: erratic idling, poor throttle response, or the smell of fuel at the base of the float chamber. After cleaning and installing the new parts, the carburetor will run smoothly through all RPM ranges again.

Replacement takes about an hour using a hex key set, screwdrivers, and carburetor cleaner. Before reinstallation, ensure the main jet, pilot jet, and jet needle match your existing setup.
