Haha funny you mention that because that’s exactly where my mind went too. I bypassed the box and followed a YouTube video on static timing to see if it would operate the same as the newer DS2-1. Seems like with this orientation (box removed) it’s sending a constant signal to the coils. The test light never turned off.
An ignition requires pickups and a "driver" for the coils. Both the III and S use Hall-effect pickups. The driver is a big transistor, usually a Darlington-pair BJT (bipolar junction transistor) or IGBT (insulated-gate bipolar junction transistor). In the Dyna III, the transistor is in the box. In a Dyna S, the transistor is on the pickup plate. So a Dyna III pickup plate, by itself cannot control the coil to make a spark (as DOHC said). The Dyna S pickup plate can.
Alright guys, I got the new Dyna S installed last night and all put back together. She runs like a beast again! Didn’t take any pictures because I was too excited to get it back together to get a quick test ride in before it got dark. Will get some soon.
Did a plug chop test and the plugs were a dark golden brown with a hint of ash on the tip. Little more fuel needed maybe? Running a .030” gap. Fuel screws at 2 full turns out from lightly seated.
A couple of things came to mind as I was putting the bike away in the garage last night. As I was timing the Dyna S, it seemed as if there was a decent amount of play when trying to line up the timing markings. I couldn’t figure it out but I timed it to as close as it would let me. Would the play be from the advancer nut notches being old and worn out? My OCD is telling me to buy a new nut and bolt and re-time it for safe measures...
I then realized that I might need to bump up my pilot jet size. I’m running 17.5 pilot and 117.5 mains. I didn’t mess with the needles so I have no clue what they’re set at. I feel a 20 pilot would help after researching some others jetting combos with similar pods and exhaust set-up.
