What do I use for a spark plug socket?

I can't get my normal spark plug socket down into the tube to unscrew my plugs.  How do I get them out?

It seems every Vulcan 1500/1600 owner discovers this eventually and then they have one of those Homer Simpson "DOH !" moments when reminded there's a spark plug socket in the bikes tool kit. That's the easiest solution but if your bike didn't come with tools it's time to head to Sears. Look for the 18 mm spark plug socket part number 43330 (online at sears.com ) or 50728 (in the store). It's a six point thin wall socket that will fit perfectly down into the deep spark plug tubes on the left side of #1 cylinder and right side of #2
