swap O2 sensors
clear codes
start 'er up and see if the code goes to the front

Thanks for the idea to switch O2 sensors, will try that this weekend

identified a faulty rear O2 sensor a couple of weeks ago by swapping them
mine were interchangeable (09 Fatbob)
I believe yours are too
better check first

update, gave the bike a tune up new plugs, air filter.Cleared the code and have put 50 miles on bike. No codes as of yet, will moniter. Thanks for your guys impute. If it appears again will switch the O2 sensors.
