WE’RE EVOLVING THE T4 JUNIOR PLATFORM TO CREATE A CLEANER TRANSITION FROM MINI TO JUNIOR, DELIVERING BETTER DRIVABILITY, IMPROVED BALANCE, AND MORE CONSISTENT PERFORMANCE ACROSS THE CLASS.

 

WHY THE UPGRADE?

  • 🔧 Replacing the FM122 with the FM19 carburetor Designed to better match the Junior weight class, providing smoother throttle response and improved performance consistency.
  • ⚖️ Fairer Racing Conditions: The FM19 configuration reduces gray areas and helps prevent carb-related advantages — creating a more level playing field for everyone.
  • 🛡️ Longer Engine Life: Combined with the new air duct system, this setup promotes better airflow and cooling, helping extend engine durability.

 

UPGRADE KIT INCLUDES:

FM19 CARBURETOR

82 MAIN JET

33 PILOT JET

CNC INTAKE MANIFOLD

AIR COOLING DUCT

 

REGULAR PRICE: $368.81
