Joe, that is a 75, the Martec has been in it for ???? how long? If it isn't broke??? If in doubt got to the SOHC and talk to Hondaman, that is one of his areas of knowledge. ALso, as I recall, Red was pretty wise on those things, and I think, someplace, I have some paperwork on the Martec ignition.  Cntrhub is quite knowledgeable on alot of stuff, so I am not discounting his thoughts either, but the coils on there have been there awile.

Just in case you need them, got a deal on some 3 ohm Dynas!!
