Hi everyone, I am replacing plug caps on my 1953 Mk1 square 4. Can I use suppressed caps on the bike. I am having trouble getting NGK caps for it, Draganfly say they can’t find a supplier. Any help would be appreciated. Thanks Peter Smith.

suppressed caps are fine on a standard coil system and will annoy the neighbours less. Do unsuppressed ignition systems still interfere with TV signals, I guess not as it all arrives by modern magic these days rather than old fashioned magic?

hi you can try euro car parts or the big motor factors or phone NGK and they will tell you who stocks them , but i get my caps on Ebay a lot cheaper , but i use non suppressed caps and copper leeds and it doesn't affect modern TVs etc

The VMCC do a champion resistor type…

Not really recomended with Magnetos. Nev

these people seem to have plenty of the non resitor caps if thats what you need , ie 8710 type .

cheers

They must have bought a lot as NGK don't seem to make them anymore.

I think they might be made under license by Wassell. I bought 4 of the non surpressor type black NGK ones from the VMCC shop a few months ago for my square four
