Tonight when I replaced my spark plug the wire that goes into the rubber cap that fits over the spark plug pulled out. Did the wire tear or does the wire just get stuffed into the opening on the rubber boot and then it is secured by a zip tie? The bike runs but I'am wondering if I'am getting a weaker spark. Also if this is not normal can I just buy a new wire with the rubber plug boot attached or will I need to buy a new ignition coil? Once again thanks for the much needed help.
