Bus Er
Well I was coming back from having the bike looked at at the dealership because I had the ipod interface put on the bike and on way home the radio died. So I took it in to have them see what happened and it appears that in the process of the new guy washing the bike he got water in the input jack and well fried my radio... The dealership didnt have a radio in stock to replace it with but said that they would have one in for me in a couple days. So on my way home running down the interstate the digital part of the gauges go to Bus Er all other gauges stop working lights go out. Bike didnt stop running but I pulled over on side of road and turned it off. I waited about 1 minute to crank it back up. It cranked up fine and Bus Er went out. Any ideas? Think something else was jacked up in process of radio going out?

buss error... a problem communicating between the speedo and the ECM.
Sounds like they washed your bike with a fire hose.

If Harley Davidson speedometer reads 'BUS Er' with the ignition key switch turned ON (engine stop switch at RUN with the engine off), check serial data line for an open or short to ground between diagnostic link [91A] terminal 3 and ICM connector terminal 12. Check for an open diagnostic test terminal between diagnostic link connector terminal 3 and ICM. With ignition key switch turned ON, transmit data should be typically 0.6-0.8 volts. The range of acceptable operation of the serial data line is 0-7.0 volts. For a quick check of speedometer function, a 'wow' test can be performed. Press and hold odometer reset switch then turn ignition switch ON. Release reset switch. Background lighting should illuminate, gauge needles should sweep their full range of motion, and check engine, battery and security indicator lamps should illuminate. The security lamp may illuminate even if the vehicle is not equipped with a security system. If instrument module fails 'wow' test, check for battery, ground, ignition and accessory wiring to speedometer.

Had the same problem driving across route 80 in PA in a heavy rain storm on my way to the HD museum last year. Bike did not die but when I pulled it off the highway and shut it down, it would not restart. We had to pull the connector off of the back of the radio to unload it from the bus. Bike ran fine after that. Radio had moisture in it as I could see it in the LCD the next day. Everything else was fine and after a new radio no further problems.
