Not sure how long you had the key in the run position. If not long and the battery got weak you might want to keep an eye on the battery. Do you know the age of the battery? Check the water level and keep on the charger. The bike likes a strong battery.
If you were learning the radio controls you might have had key in the run position for awhile.

Anytime I want to change radio or clock settings I have to grab the manual and read.
