CRF300L EJK Fuel Injection Controller

EJK, short for Electronic Jet Kit, provides the best available EFI (Electronic Fuel Injection) controller for the 2021+ Honda CRF300L and 300L Rally. We recommend this product any time you are installing an aftermarket exhaust and air filter on your bike.

Benefits on a Stage 1 Honda CRF300L:
If you've decided to add an aftermarket exhaust and/or intake system (Stage 1 mods) to your CRF300L, 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.
