I recently bought a 2001 honda cbr600 f4i for 0, i have since fixed it up and got it running, now im wondering... below the spedometer there is the letter "A" i beleive, and if you push one of the buttons next to the spedometer it changes to a "B" i know i should know the answer and i tried to find it in the manual but its not in there, any assistance would be appreciated. thanks.
