If I leave my bike standing for a couple of days it just won't start. I switch off the alarm, which leaves nothing drawing current when I leave it. I've heard that it has something to do with the CDI which just won't entertain anything less than 12 volts. The battery is good, but obviously it will drain over time. Is this normal? and if so what can I do about it? If i can't trust the bike to start when I want it to it is no good having it. Does anyone have any suggestions or has had the same problem? Thanks in advance Bob xx
