Always used to use Boyer back in the 80's & 90's, don't think there were too many other options at that time. Never ever had a problem with at least 3 of the Triples I converted to them. I certainly would never by choice use the standard points ignition.
I'm now rebuilding a couple of A65's and am going to use the Tri Spark unit.
They have a non backfire timing advance to make kick starting easier, hoping this works out okay as I've had 2 knee replacements on the RH knee
