Guys
What is the best spark plug for my 74 Six Days?
It came with a Bosch W3AS.

Hi Rick,
  I have been using Champion L78 plugs since the early 70s on my 100s & 125s and never had a problem. They are reasonably priced.  Cheers, Lee

Whatever plug you choose check with your local auto parts store for price & availability as they are often less expensive.
