Few days ago when i installed new levers, my bike wouldnt start after a ride. When i tried tos tart it some strange buzzing noise and thats it. I took out battery and charged it, put it back in the bike, and it started all normal. Then took short ride after that, shut the bike of, and after 1 min i wanted to start it up again saim problem. Till 2 days ago when i took battery out charged it and it lasted trough rides till yesterday. My battery died when bike was on and i was riding it hard beafore that, but i stoped at the stop light and turned on turn signals and thats when bike wanted to turn of but i kept it by rewing it. Speedo was deemed a bit, only back light and nothing else was showen. Wehn i was going back home it turned of, and i had to push start it but speedo was back on like battery charged trough that previous ride. This problem happend a lot trough this few days. I went to local shop to measure voltage, but they said battery is problem and it only shows 12.20 V, even when i hold rews to 4k rpm. What can be the problem???!? Sorry if some one does not understand im kinda frustrated becaus of this prob, and engl is not my native languge...
