spark plug wrench
« on: April 09, 2018, 05:07:36 PM »
Very basic issue. I struggle with spark plugs 2 and 3 on my cb750. Is there a wrench or socket that works better than others? My 18 mm long socket is a bit** to get out of the plug well with any oil on the fingers whatsoever.

 Look for a stock plug remover from a Honda tool kit. Sure some aftermarket on E-bay. They do not fit on a ratchet but are designed for the bike. Also some sockets are thinner then others. My Craftsman deep well with a rubber plug holder inserted works pretty well with a short extension attached.

 My brother used to have a stock Honda socket with a 3/8 drive adapter welded into it. I use a thin wall 18mm deep with a piece of rubber hose inserted to grip and hold the top of the plug.
  I had a bike recently that had 5/8" plugs, that threw me for a minute but I realized have a Honda socket with an allen wrench swivel top on it and it fit nicely. (From a newer bike)

 Champion spark plugs can mess with your head a little if you find those in an engine, they are a little smaller,17mm I think.  Ran those a lot back in the 80's as they were dirt cheap and they were sold everywhere. Seemed to work good.

I also made a simple plug "stater" with a short chunk of hose that fits over the plug end.  Easier to wiggle into plug 2&3 and give it a couple of spins to start then use a socket.

 I also use a starter hose and put a barbed tee on the other end to turn it with. It will still slip if you're not started right.    You can feel it thread down and tighten it with the socket.

I have found some engines are tighter clearance on 2 and 3 than others.  I had a k2 that was much tighter than any other I have had.  The factory tool kit tool is the cheapest and easiest option.  I also have a socket that was ground down on the outside, then I cleaned it up in a lathe.
