I purchased a Lightspeed Engineering Electronic Ignition (Dual) and started the install. But, since I hadnt yet installed the crankshaft seal, this was accomplished by boiling the neoprene seal in water and installed with bike tire spoones. Installed spring and permatex to seal. A 5/16 stud was made to use as a drill bushing to drill through the a mounting plate that came with the kit. Fairly simple and straight forward set up, but need to be careful to correctly orient the plate. Instructions are not perfectly clear but dooable. Holes were drilled with a #7 drill for a 1/4 - 20 tap. The instructions called for #6 but #7 worked better.Ready now to set up clearance of the trigger mechanism plate.
