I recommend a good Repair Manual: Factory, Haynes, Clymer etc.
Brook has a pictorial of his work on an R75/5:

Thanks - what I needed. Anyone have a video on how to time an R75/5 with a Dyna III (I think it's III) ignition?
I was going to say I don't know of any videos...they weren't around went I installed mine. All I had were these instructions:
https://w6rec.com/dyna-iii-ignition/
Then I tried to find info on Dynatek's site but some of it seems to be removed.
Try youtube...I searched Dyna III and a couple of videos showed up.
Obviously, the Dyna III has dual pickups which sense the magnet that is embedded in the donut that is screwed to the shaft of the advance unit. I'm sure the instructions give some guidance to preliminary locate the donut and then you use the individual adjustment for each pickup. Seems like I fiddled a lot and used my timing light to view the timing marks. If I had double images, then I began to move each pickup to reduce the double images. If I'm not mistaken, as you look at the timing chest, the pickup on the your left is for the bike's right cylinder...kind of confusing, but I think you can see what I'm talking about. I recall starting the bike, note the images, shut off the bike, make an adjustment, restart the bike, check images. Repeat until you get a single image in the timing window.
