spark plug wrench size
 

Anyone know what's the right size wrench for the 2NF (XT600, -87) spark plug? My current ones seem too big. Have to get a new one but I quite couldn't measure the plug (the well is pretty deep!).

Should be a 18 mm. The problem is sometimes it needs a thin wall socket to reach down in there. I use a ground down tool kit socket.

I had a hell of a time getting the right wrench. it should be 18mm and thin walled and SHORT(but not too short 4.24"). I have a nice one i'll sell ya.... I bought the factory wrench kit with all the various wrenches you might need on the road for $50 and now I have an extra socket.

Thanks guys! I think I located a dealer here with a 18mm plug wrench. Just have to see if it needs to be shortened or filed or what.
