I had never changed the plugs on my Victory Kingpin, so I was a little nervous. But, I had my bike up on the lift while doing an oil change, so I figured I might as well change the spark plugs. They were a bit tricky to remove - I ended up using some needle-nosed pliers and they worked perfectly. Anyway, after I got my extension bar on my ratchet and got the old plugs out (the one in the rear was pretty crappy looking), I was able to put them right back in with no issues. I snugged the plug wire boot back on them, lowered the bike down and it fired right up. Works for me. :)
