Carburetor Maintenance Tips

Regular carburetor maintenance keeps your motorcycle running efficiently:

1. Clean the jets — Remove and clean the main jet, pilot jet, and needle jet every 12,000 km or as needed.
2. Inspect the float — Check the float for fuel leakage; a waterlogged float causes rich running.
3. Replace the needle valve — A worn needle valve and seat causes fuel overflow and flooding.
4. Check the diaphragm (CV carburetors) — A cracked diaphragm causes poor throttle response.
5. Use a rebuild kit — When multiple seals and jets need replacement, a complete rebuild kit is more economical than sourcing parts individually.
