    Anyone know why a 18mm socket can't seem to find anything to grip when going in for a spark plug? Not even the bike's stock tool can find anything to grab. I peeked in there and barely see the spark plug but it's got like a 12mm-ish hex on it, dunno if I should turn that one or not. Note: teh googles said the 97 Shadow Spirit spark plugs are removed with 18mm. Note 2: I've never changed a spark plug in my life.

    • Spark plug socket has a rubber boot that slips over the plug you'll have to push a little bit until the socket seats over the plug, when re- installing the new push the new plug into the socket and thread in by hand only, until the plug is threaded in. If you cross the threads using the ratchet to thread in the plugs, you are gonna be really bummed out!

    • I have an 03 and do believe it is an 18 mm but I had to make my own socket. The thickness of the 18 mm was too much. I think I cut 3/4 inch or so off an 18mm socket then welded it to the end of a 12mm socket

    • I also used a peice of 3/8 fuel line over the ceramics of the plug to screw it out and in

    • I just spent the $18 and picked up the spark plug socket made for Honda at the local shop. Works perfect on any Shadow.

    • That's great but I mentioned, "Not even the bike's stock tool can find anything to grab."

    • might be this, I certainly didn't consider pushing against rubber to find a grab, thanks, will try

    • Stock tool is worthless in my opinion. Wouldn't work on my smaller Shadow. Socket from Honda has worked on everything. Don't know why, it just does.

    • Invest in a pair. Even with the rubber boot i lose grip. Plug and socket fall in.
