Yamaha Blaster Mikuni VM26 Jet Kit
Proper carburetor jetting is critical to Yamaha Blaster performance, throttle response, engine temperature, and reliability. This Yamaha Blaster Mikuni Jet Kit gives you a useful range of main jets for tuning the factory 26mm Mikuni VM26 carburetor.
Instead of purchasing individual jets while trying to dial in your carburetor, select the jet range appropriate for your Blaster’s current engine and intake/exhaust combination. Use our Yamaha Blaster VM26 jetting calculator

Yamaha Blaster VM26 Jetting
The correct main jet depends on the complete engine combination as well as riding conditions. Exhaust system, air filter, airbox configuration, reeds, engine modifications, elevation and temperature can all affect the amount of fuel the engine requires.
When tuning a two-stroke, start with a safely rich main jet and work toward the correct setting rather than beginning too lean.

Built for Yamaha Blaster Owners
Ken OConnor Racing specializes in Yamaha Blaster parts, engine machining and complete engine builds. This jet kit provides the range of Mikuni main jets needed to properly tune the original-style 26mm carburetor as modifications are made to your Blaster.
Important: Jetting recommendations are starting points. Final carburetor jetting should always be verified for the individual engine, fuel, modifications and riding conditions.
