Fuel and Intake

XT250 '18 - '22

The EJK evolved out of the need to address the ever-increasing complexity of factory fuel injection. For the newcomer to the market or professionals wanting an easier method for tuning fuel injection, the EJK is a customizable solution for the rider that wants to take control of their tuning needs.

This unit is a piggy-back EFI controller because it does not replace the stock ECU, but rather monitors the signals to the injectors and makes fuel adjustments based on the mode settings. The GEN 3 has a push button interface allowing access up to 6 different modes to allow for quick fine tuning by the end user without needing a computer.

Key Features:

  • No computer or dyno needed!
  • Plug and play, simple to install, base settings preset
  • Unique load based technology
  • Full range tunability available
  • Does NOT interfere with stock ECU operation
  • Simple push button adjustment interface
  • Water-resistant 
  • 2-Year warranty
  • Compact size - 2.2" H x 3.4" W x 0.5" D

The plastic fitting that secures the stock choke cable to the carburetor is delicate and easily broken. A broken fitting can cause hard to solve idling and running problems.

CNC machined from billet aluminum and anodized black or blue. If you want to retain your handlebar mounted choke this may be the solution.

  These no longer fit the new version of the ProCycle Remote Choke Cable. Will not work with the long or short reach choke knobs.
