18mm spark plug wrench

[chilidawg]

Does anyone know a brand of the above wrench that will work with my 82 with 83 crash bars?

I have now bought 2 and neither will fit past the bars on all but cylinder #4, so it's either loosen the bars every time or get one that fits.

Motion-pro was the last one, looked good on Amazon so I dropped $30 on it, inc shipping.

Trying to gauge the mixture setting on my new Weber, hard to do without being able to remove the plugs on a regular basis!

PS. Anyone who wants this never used motion-pro, yours for $20, free shipping.

I use a deep well socket.
If that won't work then your crash bars have gotten bent up and in.
That was the case with my left guard.
I bent it back with a bottle jack against the frame.

Agree on the bent engine guard. Had the same issue and fixed it the same way. You should be able to get all 4 plugs out! (Don't toss that spark plug wrench just yet!) :shock:

No Dan, the bars ain't bent. It's the 13/16th hex nut on the top of these wrenches that's the PITA.

Right now I'm pulling my plugs after every ride of 50 miles+, checking electrode color, searching for that elusive light tan color and I really don't need to be busting a plug in my newly rebuilt heads.

I really need to get a wrench that has a real rubber insert to protect against this.

As Dan said just use a deep well socket in 3/8" drive preferably

Do you use a 13/16 socket on them or a wrench? The socket on extension should allow you to turn the plugs..I also have bought deep well sockets for my use and the 18 works like a champ.. also fits my shock mounting bolt on my f150 lol

This is the one I use. Works fine on my 78 with 1100 crashbars. Less than $5 and available locally (US).

I apply counter force on the ratchet head which keeps the socket centered on the plugs.
I've been doing it this way for years and many many times while playing with my weber mixtures with no damaged plugs.
That craftsman socket is a good deal.

I use the one for CB750K. It works for me.

you can also stick some foam pipe insulation in a regular socket to mimic the rubber in a spark plug socket

The last Honda plug socket I had, was for my 3 year old 360T. It didn't have that rubber support washer.
Did any of those tool kit plug sockets have that?

Thanks for all the replies guys, y'know I never had this problem all the time I was using Champion spark plugs but his time because of all the work I'd done I decided to use the Denso's that where recommended by mother Honda for regular high speed running, after all, this is Texas, if you ain't doing 70+, you get run over.

Turned out they where 18mm and not regular size. First thing I noticed was that none of my plug wrenches fit, so I borrowed an 18mm deep well socket from a friend to install them initially, (before the bars went on.) I've been building this thing for 14 years and never needed a deep socket, that's why I never bought a set.

So now I've ordered a good deep well socket and intend to pull the insert from the motion pro to make it work one way or another. So right now, I own my first (extra long) deep well socket and of course it's no longer for sale due to that.

I hope this thread helps others sometime, and as I said, thanks for all the help and replies! :wave:
