Description
ProX Mikuni main jets provide accurate, consistent fuel delivery for the Yamaha Blaster YFS200 stock Mikuni VM26 carburetor. These precision-manufactured replacement jets are clearly marked and available in multiple sizes, making them an excellent choice for routine carburetor tuning and engine modifications.
The main jet primarily controls fuel delivery from approximately ¾ throttle through wide-open throttle. Selecting the correct Yamaha Blaster main jet is essential for strong performance, clean throttle response and engine reliability.
A different main-jet size may be required after changing the exhaust system, air filter, airbox, carburetor, cylinder porting, engine displacement or elevation. Temperature and other weather conditions can also affect the required jetting.

A larger-numbered main jet supplies more fuel and creates a richer air-fuel mixture. A smaller-numbered main jet supplies less fuel and creates a leaner mixture.
Always verify the required jet size before ordering. These jets are intended for the stock-style Mikuni carburetor and may not fit aftermarket carburetors installed on a Yamaha Blaster.
Jetting requirements vary according to engine condition, modifications, fuel, premix ratio, elevation, temperature and humidity. Begin with a safely rich setting and make one adjustment at a time. Running a two-stroke engine too lean can cause overheating, detonation, piston damage and serious engine failure.
