An economically priced replacement carburettor for four-stroke motors.

The riders of Vespa ET-4 125/150cc and APRILIA/PIAGGIO models with the veteran PIAGGIO 'Leader' engine can count themselves lucky! This newly produced run of 24mm carburettors finally provides an adequate alternative to the original MIKUNI BS24 carburettor type, which is sadly long out of production.

• 24mm diameter
• Includes an electric choke.

The GY6 24mm carburettor is also perfectly suitable to complement the tuning of GY6 50cc engines with performance cylinders from 85cc. The carburettors are factory set to fuel the 51mm bore cylinder from NARAKU, but with a suitably adjusted jetting are easily adapted for use with other engines!

Their most welcome feature though has to be their suitability for the PIAGGIO Leader 125/150cc four-stroke engines. The purchase of overpriced used MIKUNI carburettors, or even the cost of their expensive overhaul due to a lack of alternatives is no longer necessary! The NARAKU 24mm carburettor replaces the original MIKUNI BS24 almost 1:1, and new carburettors should always have their jetting checked and adjusted before use. The throttle cable on the GY6 exits on the opposite side to the MIKUNI and will eventually require replacement to be 100% true to the original.

Conclusion: An economically priced quality carburettor to provide more power to tuned GY6 engines, or to reactivate and service aged PIAGGIO Leader engines!

Our recommendation – The TOP-TIP:

• Do not forget to check and adjust the carburettors jetting to suit the engine to which it is fitted before use!
• check your manifold rubber is the correct size 32mm, the earlier engines use a smaller manifold rubber so these will be a very tight fit
• Check the Main jet, 
• Main jet set, 
• Idle jet set,
