You know you want it
Our family has four CRF250L Rallies and as Dad I’m the one who winds up doing all the wrenching. We have one 2017 and three 2018s, all of which came from Honda with the slightly larger header pipe and therefore did not need a megabomb header. The 2018s all have FMF Q4 pipes, the 2017 is stock. All have enlarged holes in the air box and K&N filters to breathe better. We ride about 50/50 onroad/offroad.
Okay, so first off, the EJK is pretty simple to install if you have basic mechanical competence and a 10mm socket. Having small hands would help also, but I don’t and it still wasn’t bad. Basically you remove the seat and plastics off the left side of the bike, unplug the injector wire, and this unit plugs in between the factory connector and the injector. A bit hard to get at but very simple action. The instructions are good enough if not fantastic. Fire it up, programmed to the EJK’s recommended settings and was not at all impressed. It backfired a lot, tried to die when you chop the throttle, and seemed to be way too rich. Got online to see what others had found for sea level, tried those and it helped a ton. Biggest initial impression was that it doesn’t make any difference. Any power increase was minimal, and because this thing doesn’t actually plug into the O2 sensor it has no way to automatically adjust or learn the bike. So why four stars? Well, after riding it a while and comparing it to a stock bike I realized it does actually help. The bike does make a bit more oomph throughout its range, most importantly (perhaps) up at the top end. You will be hard-pressed to notice, honestly, but if you want to hold 70+ mph then it makes a difference. It also accelerates just a smidgen faster, IMHO, but again you’d have to ride back-to-back with a stock bike to notice. Would I buy it again? Yeah, I’m just dumb enough to want every last gram of power I can get, plus I feel better knowing the engine isn’t running super lean anymore. But does it actually give a 4-6hp increase like they claim? No way.
