The Key Star carburetor fuel adjustment kit includes almost all parts that are required when maintaining and adjusting the carburetor. Parts include needle valve, idle screw (air screw), float chamber gasket etc. and fuel adjustment parts that come in an abundant variety.

The outraging performance is surpassing than the OEM product. Tune up jet sets that are sold in the market have sizes with equal measurements. For example multiples of 5 or 10. But the jet set of this fuel adjustment kit does not have equal measurements.
It is designed with sizes that can change the air-fuel ratio efficiently and definitely. The first aim of the fuel adjustment kit is for trouble shooting.
It is to be used for motorcycles that have trouble in fuel supply. To increase air fuel ratio, pilot jet, jet needle and main jet all need to be moved to L direction and on the other hand to reduce air fuel ratio, they must all be moved to R direction. Depending on how you want to change low speed range, medium speed range and high speed range, the combination of the L, S, R will also change.
That is the joy of carburetor tuning.
The other aim of the fuel adjustment kit is for motorcycle tuning (to improve performance). However the carburetor does not energize itself, so there's no use adjusting the carburetor itself. When you are tuning up the engine by replacing parts from the front and rear of the engine, performance will improve if you adjust them to correspond to the vehicle. For example if you replace them with an air filter that has more air flow or exhaust that reduces exhaust resistance, the condition of the air fuel mixture that the engine requires will change. That's when carburetor adjustment is necessaryAnd that's just what fuel adjustment kits are for.
