After some thinking decided on Dyna S. Reached out to Dynatek, super responsive support. With current 5% ebay bucks offer - ignition was like $100, worth it for me to replace points and not worry about all little pieces and adjustments. Will use stock coils for now but can easily upgrade to Dynatek if ever needed.
Some useful info I got from Dyantek, maybe helpful to someone:
If you have a Dyna-S ignition, the Miniature series coils (DC1-2) will not work. The DC1-2 may Only be installed if using an ignition with an active dwell control system, such as the Digital Dyna 2000. The Dyna-S has a fixed dwell and will overheat and destroy the DC1-2 coils and/or the Dyna-S very quickly. The DC1-2 may be suitable for use with the factory electronic ignition, but may place an added strain on the igniter module.
If you have a have a point ignition currently, or factory electronic ignition, the Dynatek DC1-1 coil set will be a much better option to use.
Should you have a point ignition, 5.0 ohm coils will be needed and our DC8-1 would be appropriate.
In either case, you will require new spark plug wires, and our DW-200 would be a great choice.
The DS2-2 Dyna-S and DC1-1 coils, along with the DW-200 spark plug wire kit are a time tested, reliable set up on these engines at an affordable price.
The factory ignition coils will also work well and can be replaced at a later date, if desired.
There are no counterfeit Dyna-S products in the Japanese product line. However, if you find a set of green, dual output coils that are advertised as "Just Like Dyna Coils" these are counterfeit and should be avoided at all cost.
