Errors P0171 & P0172

Hi,

Have these errors, system too rich/system too lean......has anyone else had this issue and know what the fix is?

Bike runs fine, the engine light is on....other wise ok. Will pull it apart on the weekend and check the basics, just thought there maybe a known issue.

Thanks in advance.

Thanks,

Yes forgot to mention it has a Rexxer tune which eliminates the 02 sensors.

I re flashed the tune and engine light has now gone away.

All good!
