Roy Bacon lists Tour Trials 52-56 NA8, ISDT 52-54 NA10, Scrambles 52-55 NA12. Racing Clubman 52-63 NA14. All Champion.

GS Ron in Calif runs a BB so maybe he has some advice on a modern plug.

Well, unless you are racing you have many choices... NGK you can run a B7ES, and any B7E type plug... and of course you can cross reference that to a Champion.. or others.. If you are racing, go colder to a B8 or B9 range.. if you have high compression try to get a B10 range.. Most spark plugs today are now resistor types.. so you may only find a BR type plug...

Then there are the more expensive types that use a fine wire.. they take less voltage to fire AND they are very hard to foul out... BR7EIX, B7EV, B7EVX, BR7EIR... some of those are now obsolee, but some shops have some old stock...

If you are running a Lucas magneto, then remember to gap the plug down to 0.018" to 0.020".

Cheers..!!

Ron

Thank you ! It has a NGK BC-64EW plug in it now and it starts easily. Napa says no deal.... I have B7ES plugs so I can try one of those. The other plugs sound good too. Wonder what my plug was for? Its what came with the bike.....Good tip on the Magneto gapping .

Hi Wade... those fancy plugs were a pain... not really sure why they were used.. the side gap plugs run really cold and foul very easily.. I should of mentioned that in colder climates guys run the B6 plug (hotter).. Those of us that run modern ignitions run B8 or B9 plugs, and have no problems...

The BB head has spark plug inserts from the factory, and I wonder if that makes any difference in heat transfer..?

Also check out this thread... similar info.. stated better..

B7EVX is the only one still available from NGK through NAPA... The question is --- Since it would cost 65 dollars for 4 of them is it worth it to have them.? Or should I just run the usual B7ES plugs?

So I bought these plugs which someone recommended. Came in a box with English and Asian writing. Boxes look older but the plugs have a plastic cover on them which looks newer. I dont really care unless the plugs are crap. Havent tried them yet since the bike is not roadworthy yet. But I am working on that....
Any thoughts on these plugs?
