image001.jpg Doug, This picture of a dual points setup on a Pentacom plate comes from an article in VMCA Vol. 8, Issue 2, page 17. (Look under the magazines tab on this site) The intent of the dual points in this article was to provide dual ignition systems for double plugged engines by adding a se...

Steve,

There was a post on a points beancan rebuild here as well.

Mal, Werner,

The handlebar switchgear on the bike and in Werner's pictures are both correct /6 era switchgear.
