Just had the bike receive its 20k service. I have ridden it maybe 70 miles since the service and the check engine light turned on. I am only getting one trouble code:
I then started the bike and monitored the F ADAPT FUEL = 76.0 & R ADAPT FUEL = 103.5
Service consisted of changing: Spark Plugs, coolant, front fork oil and seals (I asked them to), Oil Filter and oil, etc.
I know when they change the plugs they drop the engine.
I am wondering if they did or forgot something when it was placed back into position or if a sensor just needs to reset?
Elevation is at 4,500ft
I am the 5th owner and have only placed a total of 150 to 200 miles total.
91 Octane fuel.
K&N Air Filter
Thank you in advance for you support and help.

The spread between the front and rear O2 sensor is too great, that's what the error is showing. The front is being leaned out for some reason, could be any number of things.
Possibly too much fuel being sensed by the sensor, so the ecm is taking out fuel little by little. It's gotten to the point that it throws an error now. I'd be looking at the injectors (sticking open) first. Other thing to look at is the O2 sensor itself. Not likely to go bad, but it does happen.

Air leak in the front intake?

You do not have to drop the engine to replace the spark plugs. The front isn't easy, but lots easier than dropping the motor...

First, Thank you all for you wisdom and guidance in helping me solve the issue with my Buell 1125r. It is much appreciated.
I was able to find the problem(s). First, like D adams mentioned, O2 Sensor issue. The sensor was fine when it was brought in for service, but when released after the 20k service; there were a number of items not done correctly. One being the O2 Sensor was not correctly place back/zip tied.
Notice it hanging in front of the exhaust manifold. When I would accelerate, it would press against the exhaust manifold, then if finally melted the connection and shorted it out.
Wire harness was not placed back into the tray nor was one of the clips for an additional sensor.
Once of the AirBox bolts was stripped out.
Then the best for last... The oil was filled completely to the top of the dipstick/fill port.... this is mechanicl/tech school 101.
I will give credit to Harley Davidson though. When I called and explained the situation, spending $1,215 to have the bike serviced and completely gone through. If they found anything wrong or might be needing repair, I authorized it. Then getting it back in this condition. The Service Manager apologize profusely. They picked up the bike at my house and are going through it from front to rear and he personally is over seeing this.
It is not how you start, but how you finish that concerns me. I have a saying that I use with my employees "slow is deliberate, deliberate is accurate, accurate is fast."
Thank you all again, I will let you know how it finishes. Hopefully there will still be summer left to ride...

Incompetency reigns supreme. That stuff is just unacceptable, especially considering how much money you laid down. I would be pissed beyond belief.
Your story reinforces the reason I service my own bikes. It might take me a bit longer, but I will do it correctly.
