KLX125: Fuel and Intake

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
