EJK, short for Electronic Jet Kit, provides the best available EFI (Electronic Fuel Injection) controller for the 2018+ Kawasaki KLX250. We recommend this product any time you are installing an aftermarket exhaust, intake, or when you just want to make your stock bike run better.

Fitment: 2018+ Kawasaki KLX250 / KLX250 Camo

Benefits on a Stock Kawasaki KLX250:
If you're keeping your engine stock, an EJK EFI controller is one of the best bang-for-the-buck mods. The KLX250 runs lean from the factory and really falls on its face in the low to mid range when you hammer the throttle. A Fuel Injection Controller will adjust the fuel mapping, making the bike run better, helping eliminate that dead spot early in the powerband.

Benefits on a Stage 1 Kawasaki KLX250:
If you've decided to add an aftermarket exhaust and/or intake system (Stage 1 mods) to your KLX250, an EJK EFI Controller is HIGHLY RECOMMENDED if you want to take full advantage of those performance parts. Aftermarket intakes/air filters give your engine more air, and exhaust systems allow it to breath better. Without an EFI Controller, the bike will run lean and you may experience pinging or backfiring, and the bike may run hot. Additionally, without the proper fueling that an EFI Controller provides, you will see little to no performance gains from your new exhaust system and, in fact, your bike may run poorly.
