I run a Vertex magneto on the street - is an excellent ignition . . . starts very easily and has 16 degrees of mechanical advance. It is not hard on the starter as it starts the engine with the initial static advance of 8 degrees of initial. The only down side is that it has no load sensing capability, so it will not be as good on mileage as a properly setup stock ignition. BUT - it sure runs nice and is pretty much trouble free (points last forever). If you don't have rare-earth magnets, then you do have to have the magnets checked/charged every 3 or so years.
