Spark plugs

[james007]

I tried to inspect my spark plugs, but unfortunately the tool provided (in the toolkit) was too small. Does anyone know the actual size required? (NGK plugs).

:mad:

Arrrrrgh, the bloody tool kit, I forgot all about that. Couldn't start my bike this morning so went to do the plug wipe as so often promoted on this site. Got my plug socket and it wouldn't fit - I thought all plugs were uniform in size. Didn't even think about the "toolkit". Bugger! It doesn't fit either you say?

apparently the toolkit is designed for Champion plugs...

After buying a couple of wrong sizes 12mm is the one you want. 12mm spark plug tool ( the 12mm doesn't relate to the socket so measuring the plug was out for me)
