B-81 Spark plugs

Recommended Posts

What spark plugs should I use in my '79 B-81? I took out the original and it is a Blue Crown M5, all searches led to "vintage" Blue Crown plugs so I don't think they make them anymore. All I know is that the proper gap is .30 in.

Nevermind, I found it

Good deal.   Just don't set the gap to that three tenths of an inch.    :ychain:
