998cc Engine code PO136

[Butchey67]

I have a 2011 Spyder Rt SE5. I bought this bike a year ago with 2400 miles on it. I keep getting engine code PO136 , i've replaced both O2 sensors and an assortment of other things. The bike rides great, but i just can't get rid of the engine light. I replace the O2 sensor, code gets cleared then next day it returns, any idea what may be causing this ? any help would be very much appreciated. Thank you !!! No idea why photo came out that way, no idea how to correct it

Nice. Now, was this a pre-existing condition when you bought it, or did this come about after you started riding it regularly?
