Just want to check that the spark plugs on the XJ500 is 18 mm and not 11/16"

Do you mean the size of the socket to remove the spark plug?

If you do then all Japanese models are metric, 11/16" is just slightly thinner than 18mm (about 17.50mm)

If you mean the reach then there is not a lot of difference at all.

Hope this helps.

I ment the socket yes :) The reason I was wondering was that it is very difficult to find a 18 mm spark plug socket in Sweden, we have 17, 19 and 21. So therefore I started to suspect that it was a 11/16" instead, since that would not really be detectable when we removed plug 1 and 4 with a 18 mm wrench :)

It doesn't have to be a spark plug socket. Try an 18mm box spanner or a long socket. In fact thats what I use on my bike so I can use a ratchet with it.

Uhmm, I found one 18 mm spark plug socket, it wasnt that hard once I started to look :)

There seems to be no 11/16 but a 13/16 instead that is a spark plug socket, but I will use my new 18 mm :)
