Original owner of my '03 took delivery in August of '02 and put 1,300 miles on it. I bought it in Feb. of '03 ($9,000 cash!) and rode it five seasons ('03-'07). At the end of '07, with about 40,000 miles, went to fire it up one morning and it turned over slowly and clock reset; this after a full day of riding the day previous. Then it fired up. I believed the symptoms demonstrated a weakening battery. Replaced it and have had no trouble. Since I live at 5,400 feet of elevation in Montana, the winters get gottdamnded cold so the battery has always come in the house during the annual layup and is topped with a battery tender.
