About a week ago, bike would give a clicking sound before starting, and bike had problem starting (rough start). I charged battery, and then it seemed to start fine. It started fine this morning, stopped to get gas, it wouldn't restart. Had power, lights, etc.. but pressed the start button and nothing. No clicking sound or nothing. I disconnected/reconnected battery, and tried to start but nothing. After about 15 minutes, I tried again and it started right up. Got home, shut it off and tried to restart, and nothing. What could be wrong? Battery, alternator, relay fuses, starter?
