Has anyone experinced problems with their battery? I have had mine trickle charged several times. Won't hold a charge! It will turn the bike over fine the first time I attemp starting but then it's too low to turn the starter fast enough. It does recharge after running the bike for a while but then I have the same problem. I have had this problem since Feb when I bought The bike. It this just a problem with the bike overall or is the battery just faulty? My DRZ never had this problem!
