spark plug size

[mpcluever]

I'm looking at getting a color tune spark plug to help with dialing in the carbs. What size plug does my SH take? I briefly looked through the clymer book i have, but didn't see the size. Figured someone here would know off the top of their head.

The size you want is 14mm. SWMBO just bought one to sit in the tool box and look cool. Actually. it will get used on her FJ1100, when we find some time to mess with it.
