What size spark plug wrench?

I had all my plastic and fuel tank all off my 2009 today, so I thought I'd check the spark plug. Mine burns a bit of oil, so I thought checking the plug might be a good idea, since I already had the bike all naked and all. None of the spark plug sockets in my tool chest would fit. So I tried my deep well sockects. None fit. It appears the wall thickness of all my sockets is too great to allow removal of the plug.

What do y'all do when you need to remove the plug?

Use the spark plug socket in your factory tool kit mounted in the rear rack

Thin-wall, 18 mm deep socket.

I have spoken.

BTW, a REPLACEMENT spark plug, with a more STANDARD hex size, is available . . .

Champion 809(RA6HC) will work. Has a 16mm shank, easier to access than the traditional 18mm one.

Also: NGK DCPR8E (4339).

Good info! Thanks, Damocles. I wrote those details down in my Clymer manual. I'm due for a spark plug change this Winter and will probably switch to one of the 16mm-shank offerings you dug up for us.

Cool; you might be one heat range away from the OEM plug, but . . . unless you're trying for the World Land Speed Record or something, I think enough latitude exists between heat ranges to give durable and reliable service!

B-b-b-but all the cognoscenti on the internet say Champion spark plugs are icky!

Will my bikes still run if I use Champion plugs? Will I get some sort of personal rash?

I have had problems with champions over the years T. Especially in 2stroke engines but have had premature failures in 4strokes too. I won't run a champion in any of my bikes. They work fine in my lawnmower though!

Since we are kinda on plugs, does anybody but me modify(cut back) their ground electrode to increase firing surface? Seems I get the best results that way, iridiums and all those expensive plugs suck. A good ole NGK modified gives me the best performance....
