Mine is the RB Easy, but the CEL has never returned

Mine also comes and goes. It will stay on for a few days then kick off. Just odd to say the least. Bike runs great though.

I was experiencing a CEL on my 2017 KTM 390 fitted with a RB EVO Exclusive.
Bike has about 800 miles on it when i fitted the EVO and had no issues until about 1200 miles.
Would stall all the time when clutching in at stop lights and CEL would pop up after starting the bike and letting it idle for 10-20 seconds. My CEL i was getting was "o2 Sensor Low Voltage" or something like that. I would reset the CEL but it would always come back every other day. I ended up purchasing a used o2 sensor off ebay and when i pulled my old one i noticed the end of the sensor had white soot stained all over it (think the bike was running way to lean). Replaced the o2 sensor and reset the bike OEM learning map by letting it idle for 15 minutes and hook my laptop up to the RB EVO and reset the learning map on there as well. I have since rode the bike 300 or so miles with no issues so this has appeared to have fixed everything. Id say always reset your maps when you install new aftermarket parts so the bike can relearn so it can run properly.

Well, I’m coming a little bit late at this post for sure. But
I have the same exact issue with my rapid bike evo exclusive. It comes and goes
Comes and goes
The first 3/4 months everything was ok but now is doing it over and over and over. CEL is staying more on than off lately. In addition I have P0916 error code

P0916 Possible Causes
  • Faulty Gear Shift Position Sensor
  • Gear Shift Position Sensor harness is open or shorted
  • Gear Shift Position Sensor circuit poor electrical connection
It looks like the code has nothing to do with the RB but I would check all electrical connections and earth.

Ok, so
I reached out to the Dimsport Boizz and they told me the following:
It should not be any CEL, try to put the auto adaptivity max correction setting allowed to +3 and -3 and see if it solves the problem, if it doesn’t, wait til the CEL goes of and turn the auto adaptivity off as soon the changes are made. I still didn’t try it because I don’t have the wiring to connect to the pc, but if someone tries it let me know.
