I have an 2003 883 sportster. The bike has no spark at the end of the plug wire in cold weather. If it warms up to around 55-60 degrees outside the bike will fire right up! This happens like clockwork. Once it starts, There is no problems until it sits overnight in cold weather and I then have the same issue until the weather warms up and it will start right up again. I have read forums where there is no spark when hot but my problem is just the opposite. Could someone tell me what might be going on here?
