Bank 1 sensor 2 is the sensor back closer to the catalytic converter. It is not used under normal conditions, so it doesn't effect your gas mileage. I think it's just a backup to protect the cat if the other sensor fails. Unfortunately the service bulletin is saying that the ECM needs a software update, "Reprogramming of the vehicle's ECM to the New ECM Data P/N may also be needed to help prevent incidents from reoccurring (this revision contains ECM data which has been improved over the previously published ECM data). "
Here is a link for the TSB. Give this to your dealer. Knowledge is power.

Mine does the exact same thing this summer!!
After 2 week off no-use (bike's accident), I started it and 30 sec later SES came out!!
Delaer change the back O2 sensor (mine was under warranty)
Yes it could be the gas cap!! Go full it and make sure it's tight!!

Worth a check at a dealer or someone with a computer readout tool. CES light comes on with O2 sensor problem but also with low emission containment, ie gas cap not tight OR leak in the evap system. The computer monitors pressure in the gas tank vapor system based on pressure loss and number of trips. Then turns on the light. Cracks in the cansiter brought mine on. It went off after awhile and came back on again. Replaced the canister and all's been fine.
