I have a 79 R65 and want to convert it over from points. I can get a good deal on a Dyna III but I noticed that the R65 is absent on the list of applications even though almost every other "R" model is. I guess the question is will it work and has anyone else actually installed it ?

Is there any other airhead model on the list with points in a bean can ? If there is it will work on yours. If there are no airheads on the list with points in a bean can i.e. 79-80 models then it won't be suitable.

Above is were you can get a electronic ignition.

I have an 84 and I'm going back to points. I'll PM you, I need a few more bones to make mine work
-
I guess it should work because my 79 definitely has a been can.

As far as I know the R65 is the only "points in a can" model which means that any ignition system to replace points on the 79/80 model must "fit in the can".
To my knowledge the only people to ever make electronic ignition systems for the "points in a can" were Piranha
who made an optically triggered system of dubious reliability and which, in any event, is no longer available. The second is Boyer-Bransden.
The wife's R65/80 has had a Boyer-Bransden fitted for a few decades, it has proven reliable but I would not fit one now. The reason is simply that the advance curve on the B-B is incredibly aggressive, it begins advancing whilst at cranking RPM and is fully advanced by around 2500rpm - it also gives a bit more advance than stock - at least according to the flywheel marks. I have compromised by the simple expedient of timing at full advance and then ensuring the bike will actually start and if not, back off the timing until it does start reliably. As a result there is a little less than "full" advance at high revs, but the bike starts more willingly without backfiring.
If I had a points in a can model now I would probably leave it alone other than perhaps fitting a generic "transistorised ignition" module so that the points were not switching the coil (and would therefore last near forever), but if I really felt the need I would fit the stick ignition system, or one of the flasher devices from places like Emerald Isle or Siemens.
The only advantage the B-B system has is that it will happily switch the stock twin coils - the others will not.
Given that you would be up for a new coil anyway, the stock harness to connect to the hall effect beancan and the ICU is cheap at around $40, working hall effect bean cans can be had for under $100 (I just bought one from Larry on eBay).
But, and I am going to say this again - I'm not as "in love" with electronic gimmickery as I once was - if it were mine I'd leave it stock other than perhaps fitting the generic module mentioned

It doesn't look like it is compatible with the Points in a can system
It is for the system that the points mount directly to the timing cover as in the picture below
Like Tony said Boyer Bransden makes some
KIT00097 is one
If it were me I would keep the points can and install a amplifier or switch to the BMW electronic can with Hall sensor
I have the OMEGA system and it does not advance as much as advertised so I just carry it as a back up
-
If you like to tinker you can build your own points amp with a GM HEI ignition module
-
It has to be mounted to a Heat Sink
-
Another vote for a points amplifier. I've had the Velleman kit for getting on 10 years and it only cost £10.
-
a GM HEI ignition module
+1 that it can be purchased at a local parts store in Podunk USA
