Default 07 Roadking w/ 4 diag codes all o2 related any help?

I have an 07 Roadking with Kuryakyn true duels, hypercharger air filter, Fuel Pak all installed in 08. 40,000 miles and 5 yrs. later I went to throtle up and bike wanted to die, it would only take baby acceleration kicking, bucking, backfiring I could barely get home.

So with my limited knowledge I changed spark plugs, cleaned air filter, and replaced wire mesh exhaust port gaskets (I dont know if they put any back with new pipes, nothing there now) bike did run better with new gaskets, but continued same problems.

I disconnected Fuel Pak, and connected OEM ECM back up, bike ran worse. Then checked the diag. codes and found these 4:

P0131 Front o2 sensor low
P0132 Front o2 sensor high
P0151 Rear o2 sensor low
P0152 Rear o2 sensor high

I google codes not sure if there wrong? Do o2 sensors just go bad ? I'm not sure if the same OEM o2 sensors were put back on my bike in 08 or different ones.

It's winter here in PA now with snow, I'm taking the bike with me to Florida for a month, my next plan is to clear codes and ride the bike in Florida and check for new codes. Any suggestions before I have to take it to the Stealership would be greatly appreciated?

Regards,
Stache

Default Fixed most of problem

Turned out to have a hole in the gas line inside the tank. It now has more engine shaking at idle on giving times. Also after sitting in traffic for several minutes, it doesnt want to throttle up on take off.
