P0131 FRONT P0151 REAR is set when the ECM detects an excessively lean condition for a specified length of time. Codes may also set if 02 sensor fails

 

Those codes can also be caused by the nightrider o2 IED (Inline Enrichment Device).

 

According to nightrider, these codes&nbsp\\;can be&nbsp\\;an indication&nbsp\\; of an exhaust leak. Check all exhaust connections to be sure they are tight.

 

Do you recon it could have something to do with the cobra fuel processor?It has plugs where you plug the o2 sensors then plug the other end to the factory harness. And i wonder if it sets the codes when the bike first starts? Anyone else have a cobra fuel processor w/o2 connections having the same problem?&nbsp\\;The bike seems to run good though.Any ways thanx for the responses.
