Was riding today when bike started popping really loud and then it died on me. Walked it to a parking lot and the damn spark plug and wire was just hanging loose on the leftside of the bike, near the engine / fuel valve. Got to looking and the plug goes on top of the engine... underneath the fuel tank.

The plug, an Autolite 4162, the lower threads appear to be almost melted so I'm awaiting on a replacement plug from an auto parts store.

Will there be any problems with me just putting a new plug back in? I think I have enough room that I can install the plug without needing to remove the tank.

Also, has anyone ever seen or heard of this occurring? My guess is the plug wasn't fully loose or the vibration caused it to come loose? Just seems really odd.

It happens. I know a guy who rode miles over a bumpy dirt road holding a broken plug together on his Honda 350. Every time he would hit a bump he'd take a 40,000V hit. LOL. More amusing is that this was at night and his headlight would slowly droop downwards so that he had to reach ahead and pull it back up. He persevered and made it home from college to visit family.

What makes you say the plug looks melted? that sounds scary.

Well, it was the threads down near the very bottom, there is some very shiny metal sealed into those threads, looks like it was some hot metal that melted or meshed those threads together.

Anway I got some new Champion plugs and installed it, haven't rode too much but all appears to be working again.

My 2 cents FWIW:
It's been my experience with the Autolite 4162 that it is a fairly good high performance spark plug at least as compared to standard Champion or the stock HD/B spark plugs. It has a lower electrical resistance than stock or equivalent Champion which can translate to a hotter spark if the appropriate spark plug cables are fitted. Its necked-down center electrode contributes to a lower voltage requirement to make a spark.

All these things contribute to an immediate response when opening the throttle. Well, that's what we want, right?
