Plug Gap for Zenoah GT 80 ??
#5

My Feedback: (19)

Some years ago, Ralph Cunningham (Mr. Zenoah in my opinion) recommended using NGK BPMR6F plugs in the GT80 and other Zenoah engines. This is the more compact 5/8" hex plug with a taper seat and it works great in these engines. A much more compact plug than the larger stock plugs. Gapped at .025" or so ..... gap really isn't that critical on our engines.
