Fuel mileage and oil temp questions (HELP)

Yes. It is an 08 Fuel injected. Finally pulled the codes. Both O2 sensors are reading HIGH.

Rode 200 miles Saturday. Part was against a 20mph cross wind. Bike would only do 55mph in 6th. Could downshift to 5th and only run 70mph at full throttle. Averaged 28mpg for the trip. Guess it goes to the dealer today.

Did you ever get it fixed? what was the problem?
If both o2 sensors are reading high it means it is seeing a rich fuel mixture and the PCM should be trying to lean it out enough to bring it back into range but can not accomplish doing it. sound like you have a fuel control issue. O2 sensors can go bad and stay high or low but since both did it at the same time it sounds more like a fuel control issue.
 
My opinion is one of just getting used to a Harley. I myself in 2008 purchased a Electra Glide new, and it took almost a year before I forgot about my tried and true Metric tourer. Harley's not just another motorcycle, which is why you see low mileage newer ones traded at metric shops. Not that the Harley is bad, just the previous owner never gave it a deserved chance to show what a great machine they really are and traded it in. Its the character that Harley's have that other manufactures try to replicate but will never duplicate. Plus comparing a Goldwing to a Harley is like comparing apples to oranges. The only commonality is that they are both touring bikes but are completely different animals.

Took it to shop last week. They found a broke wire in the neck area that was causing the ABS and O2 senors to throw codes. they installed the newest ECU upgrade and cleared the code. Seems to be running correctly now. Mileage is up in the high 30's and running like it should in 6th gear at highway speeds.

Great that you got bike repaired. It seems odd with a broken wire, the abs and check engine light did not come on and stay on all the time.
 
is there a 'test' of the O2 sensor to determine good or bad? Or is replacing it and checking fuel mileage the way to go?

Yes you can test them.
on the 2 wire kind one wire is your signal line and one is the ground.
on 4 wire type one wire is the heater power supply one wire is ground for heater one wire is the o2 signal line and one is the sensor ground.

to test the sensor out put is the same on both style. the best way is use a scope but most people don't have access to. but warm motor at 2,000 rpm the o2 sensor should have a minimum of 7cross counts in 1 second, high to low swings in voltage, new ones will had 10 or more.
You can also hook a DVOM to the signal line and test voltage swings it should cycle back and forth between under .45volts to over .45 volts. usually you will see .2 or less on the low side and over.8 volts on the high side. you cant see how many cross counts you get but can see if it is swinging..
if voltage is fixed low under .45 volts add a little propane to the intake and see if the o2 swings high .8 or more, if it is fixed high over .45 see if there is a vacuum cap on the intake and take it off causing a vacuum leak and voltage should drop.
that tells you it is working.
to test the heater on the 4 wire type test for battery voltage on the power feed line, should have batt power, hook the meter across the power feed and the heater ground and start Bike and see if you have batt power if you do power circuit and ground is good. unhook connector and use a OHM meter across the heater circuit you should have continuity, what the spec is you would need to look up for each one. if it is open circuit with the ohm meter the heater circuit is bad.
