I have been having problems with my bike dying. It all started on Friday. I went to the gas station to fill up, went to start my bike and nothing happened. I took the battery home and charged it enough to get the bike home. I let the battery sit on the charger all weekend, took the bike out Sunday night just to see if everything was okay and I litterally watched it die at a stop light. Luckily I saw one of the guys I ride with and he gave me a push to get home( 1 min. from were it died). I just put a BRAND NEW , FULLY CHARGED battery in it today. Rode to work, 5 mins. from home it died on me again. My question is, wouldn't this be a problem with charging system? If so, does anyone have any idea if it is expensive to get the charging system worked on?
