Re: Spark Plug
My 1967 Champion catalogue lists:-
1950-64 All models Alloy heads except Scramblers and Racers Plug type N5
An upgrade would be the Champion N5G with gold palladium smaller diameter centre electrode. It has a lower voltage requirement so will spark more easily, last much longer and be more resistant to fouling.
I use Bosch W8CP (equivalent to N5G) in my 1957 G80S.
Cheers. Bruce.
