Indian Roadmaster o2 Sensor

251 0
I have a 15 RM Indian high flow air filter, freedom dual exhaust, and indian Cams. It has a power commander 5. The bike it showing a 520209 4 and 520204 17 code.
The dealer started by switching out the dummy o2 sensor plug ins from DynoJet. Codes still remained.
The next step was to reinstall new o2 sensors and a new battery, and the codes are still showing up. All the wires looks good around the plugs. Myself and the dealer are stumped. I see quite a few people have had o2 sensor problems but on the threads I have read, no one came back and included if the problem was ever solved.
Any ideas?
