Boyer measurement?

Can someone tell me the distance from the Boyer ignition stator plate face
back to the rotor face or to the top of the magnets ? This is MK3 Ignition.

I get 12.3 mm from the stator plate to the rotor plate and 9.3mm from the stator plare to a magnet. This is a Boyer Mk III on the Titanic.

thanks for that, much appreciated, Don

Quite alright. I know you're always cooking up something cool, so happy to help.

well for a one off special build I'm playing with a modified Boyer for crankshaft mounted ignition, similar I guess
to what Steve Maney offers for race bikes with no alternator. I'm setting one up with alternator which means a modified
outer primary, which is ok for a one off. I just wanted to make sure the rotor and stator plate were in cohoots with each other.
