I tried to change my sparkplugs today. I thought this would be a relatively simple procedure, with the exception of removing the fuel tank and radiator to get to the plugs. (this is a Hyosung GV250) Removing the tank was unexpectedly easy. The problem came when I got to the plugs. I tried to remove the cables connected to the spark plug gently, but that did not suffice. So, I pulled harder on the electrical cable. Suddenly it came away, and I thought I had broken the cable. The cable is connected to an "L" shaped adapter, and it appear the only electrical contact here is the end of the cable and a screw in the "L" adapter. After removing the cable, I was able to unscrew the adapter from the top of the sparkplug, and remove the sparkplug. I put a new sparkplug in, and screwed the "L" adapter back onto the new sparkplug. Then came the problem - how do I re-attach the cable (in a stiff rubber "condom") to the plastic "L" adapter? I'm not great when it comes to mechanical things, but I have a reasonable amount of experience with electrical and electronic circuits. The bare cable connecting to a screw does not seem like a reliable electrical connection to me. Because the cable is enclosed in the rubber condom, I can't be sure if it makes good electrical contact with the "L" adapter. Even if it wasn't enclosed in the rubber condom, I would never rely on on an unsecured contact connection between a bare cable and a screw in my own electrical work. So, what am I missing? Is this just stupidly designed, or am I being stupid? I have the full service manual for the bike, but it never mentions anything like this. It just says "remove the sparkplug" or "replace the sparkplug" but never mentions any of this crazy connector stuff. I have all the right tools, such as a torque wrench to ensure the plug is tightened correctly - but never anticipated that the electrical connections would be so strange. Thanks in advance for any help you netriders can offer.
