View Full Version : EFI: Code readout and interpretation?

I occasionally get an EFI light though the RS125 continues to runs fine.

The next time I start the bike the EFI light will be off and it could be many miles before it comes on again.

How are the EFI faults read out of the bike at the shop? Are they available through the instrument LCD screen? Or does it take a diagnostic reader to get to them?

Are the problems coded? And if so, is there a published conversion of fault codes to plain English?
