Went to pick up my bike from the dealer after its 20 hour service was performed. The tech changed out the spark plug noting excessive carbon fouling for only 22 hours. They gave me the plug back and recommended to just check it at the next service to see if it continues. This bike has basically taken 3 trips where it was ridden for several hours. I don't flog my bikes but I also don't let the bikes sit idling for long periods of time. The last ride was a colder day and I felt like the bike was using excessive fuel. Anyone else had issues like this with honda's fuel injected engines? I know its under warranty but I don't like sitting around waiting for the "broke" scenario so I ordered a ect sensor and o2 sensor with the idea that maybe its holding choke on with a misleading temp value or something with the o2. The only other thing I can think of would be to replace the injector. This was being run on 90 octane ethanol free fuel I drive over an hour to get (here in illinois almost all gas has 10% ethanol). The other note was that the intake valve was slightly out of spec on the loose side.
