Are you sure it's 14mm? That's 9/16" roughly. Not many plugs (sans motorcycle plugs) are that size. I'd have to dig in my motorcycle tools to see if I have one.
*edit* I checked my plug sockets. No 14mm or 9/16" plug sockets, even with the 5 motorcycle tool kits that I have. Only have 5/8". I seem to recall needing something smaller than a 5/8 once upon a time for a motorcycle. I don't recall what I used now.
its 14mm, get it from burger tuning.
