during winter i like to fire her up a few times. yesterday first problem was key wouldn't turn on at first. I leave it in the bike all the time. After giving her a hard twist, it switched to on and I heard a whining sound. Held button on a few seconds and engine would not turn over, just a put, put. Several more attempts and only get that whining sound like something spining.what is wrong and how to correct so she is ready come spring?
