31 -
The amount of air-fuel ratio feedback
compensation is maintained
continuously in the vicinity of the
upper limit (lean air-fuel ratio).

Able to Start - Yes
Able to Ride - Yes

Probable Cause:
• Open or short circuit in wiring harness.
• Fuel pressure too low.
• Clogged injectors.
• Defective O2 sensor (unable to output a rich signal).
• Malfunction in ECU.
• Malfunction in other areas of the fuel system.


The above is what the manual say, if it helps or not, I don't know.

Isnt there Fjr Owner in the area who could help you out? A bit of part swapping may help.
Other than that get a Power Commander as it doesn't need the O2 sensor to work..

Finally found out. I checked the plugs, Drained the fuel tank ,dealer sugested i picked up some bad fuel,(shell optimax).apparent bikes don't have the detonation temp of cars.to much unburnt fuel rubbish tripped the o2 sensor. So tank of fresh fuel 5 klm's later it's ok. No more light and flash code dissappeared. Thanks for the replies and help...
