Spark plugs - not what they used to be?

I was round at a pal's today (hi Bev, thanks for turning those parts!) and he was fettling a Honda Express moped from the 70s. He likes to go on cyclemotor runs now and again for a laugh and this is eligible. It is a horrible thing, made from at least 3 donors judging by the colours and sporting no! what's that? A pink Lodge spark plug? Yep, according to Bev it eats NGKs but the nigh on 50 year old Lodge just keeps going. Progress eh?
REgards, Mark

All I can say is that Kevin has a taste for them too!
Infact, I have rather more than I need now!

Just out of interest - what's the product number of the Lodge plug to fit an iron-engine 350?

The old spark plugs could disassembled for cleaning.

Spitting Bull, I don't know what plug would do, maybe whatever was listed in enfield manuals with the nearest engine to the 350 iron, or, take all the characteristics of the recommended plug (thread, heat rating, length, and several other factors, and compare to the old K.L.G., Champion or Lodge characteristics and hope to find a match.
If you do, then physically check the size and length of the plug against the recommended modern one before trying it out.
maybe our resident experts already know of an equivalent?
Lodge plugs do look pretty though...

Great question Spitting Bull – if an NGK B7HS then these are equivalents – Lodge 2HN (pink!); Champion L4G or L5; AC 430Z; KLG F80.

Thanks all, for the things to look out for and for the Lodge equivalent. I might give one a go.

a chum of mine has ancient mica bodied KLG plugs in his Panther 600's. He's done thousands of miles on them without missing a beat.

Presto! (the man!)
would you also know what the AC equiv is for KLG FE70 / Champion N-5 / Lodge HLN? AC plugs used to have cute little green lines around the ceramic.
Also, same as for Spitting Bull, but for a 1994 500 bullet please? Then I can try Tornado on something different!
