Just rode 1000 miles on a trip to No. Calif. On the last day coming home the bike lost power and went into limp mode. THe bike will start but backfires and runs poorly with no power. It threw the P0131, P0132, P0151, P0152 codes. From what I have read these are generic codes and the issue could be a lot of things. I have a Cobra module, V&N air cleaner and Python pipes. The rest is stock. The shop has been unable to figure out the problem yet. I suspect the module. They have checked the o2 sensors, fly by wire throttle control as far as I know. Any ideas?
