I have a 2002 RK, Carb, 24,000, original owner. Had the original battery till this year when the battery would not hold a charge. ALWAYS use a battery tender when home. I put in a new HD battery and after starting riding a few days battery does not seem to charge. ? Seems to come back OK from the BT but does not have enough to start the bike after two or three starts. Cleaned the connections and everything is tight. Any Ideas???
