Yesterday i went riding/training for an hour or better. Longest i ever rode since i bought it last week. When i finished & went to start it to put it inside,it just turn over & wouldn't start. The headlights usually comes on when the key is turned on,but they don't. WHAT COULD THIS BE? I bought a new battery when i purchased the bike,then had it charged @ the local auto parts store.This is my first bike & i'm clueless.
