Hi there… I am new to this group and a new CF Moto owner. I bought a 2023 C- force 600 2up and I’m having issues with the EFI light continually coming on.  The EFI light came on with only 1 km on the bike and they cannot seem to get it to stay off.  My bike is brand new and has been back to the dealer five times. They have changed the O2 sensor several times and they do not know what the issue is. Just wondering if anybody else has had this problem

The error codes are easy to read on the new ones so...and I think it even displays it on the dash.. I would think your dealer needs to review the service manual a bit closer. Some sensor is having a problem and it appears not to be the O2. Below is the error codes for the newer ones.

Ya.. it is the O2 sensor code… CF Moto just can’t figure out why it keeps popping up.. the dealer said that they want to flash the ECU but said CF Moto did not have an ECU update yet for them up use on the bike.  They said it’s a known problem on the C-Force 600. Said they changed the cylinder on 2023 bike.

Did they even try a different ECU?

Have you tried fnding the O2 sensors and wiggling the connectors?
Could be it has corrosion build up or something.
