is there a diagnostic plug?

...where the dealer can plug a Honda diagnostic tool in and find out if any errors are showing up. If so where is it?

Thanks

If you search diagnostic in the above box you will find

The engineer showed me the readout for my bike today and everything was within spec (O2 sensor was 0.429v if that means anything to anyone)

0.429V as median value?

The usual narrowband lambda sensors read about this voltage when spot on at 14.7 AFR but since the voltage slips quite a lot off this value when just a tad away from the 14.7 AFR and as the sensor ages and deposits accumulate, injection systems continuously trim for a tad leaner (sensor goes abruptly to around 0.200V) and then trim for a tad richer (sensor goes abruptly to around 0.800V) practically running the engine at 14.7AFR where the smog reducing system operate at best efficiency.

This leaner-richer cycle goes on continuously as long as the injection system operates in the "closed loop" region usually at throttle openings less than 30-40% and steady running conditions. About once a second at idle speed and 4-5 times a second at higher rpm.

Yeah, what he said!

Hope things improve for you.
