i'll charge my battery overnight, then the next day ill take to the store, go get some gas, and then to work. when i get off of work like 8 - 10 hours later, the battery will be pretty weak. to the point where the battery will die after 3 attempts cranks. can anyone explain to me how to check the recharging system. also i just got the bike and havent done any maintance to it due to lack of time. can anyone suggest what would help the bike turn on easier when its cold.
