Hi I need some help, a friend of mine has a seventies model harley 2 stroke cart it didn't have a spark plug in it. What plug should he use?

I have a '76 and a friend of mine has a '77. They both use the same spark plug. I don't know for sure that this is the plug you're supposed to be using, but I'd be willing to bet it is.

NGK - BP5ES

Now, on the top of the cylinder head it is stamped that the plug should only be a 3/4" plug. So be sure whatever you put in it, it doesn't stick into the cylinder too far. It will impact the piston and do substantial damage.
