Do an intro in the intro section please. Also give us some info on the bike like year, engine size, battery or no battery, etc...

it's a 1968 BSA with a 650cc motor and it does have a battery

Champion n3-c or equivalent. Don't over tighten, especially on a head that is hot. .35 gap should be ok. I'm sure someone else will chime in.

Champion N3C, don't mess with anything else. I'd do .025.
