Dyna S ignition timing

[Guest]

Having to adjust the thickness of the spacer is fairly common but it is a required part. It should be adjusted so all the parts move freely. Make sure to be careful and sand it evenly, just to the point that everything moves freely.

Keep us informed!

great pics of your ignition. always forget to do that. got my sons 450 started today with new dyna system. I got two 550's in the shed, a 79 and 81 to play with next so your thread will come in handy.

I timed mine with static timing using a multi-meter. From there it is just a slight nudge for advance or retard as needed.

I have a little update after emailing back and forth with someone from Dynatek. Apparently I purchased the wrong ignition (needed Kokusan version but I bought Nippon Denso) and that is the reason my rotor is short but the spacer doesn't fit right. The guy from Dynatek offered to send me the Kokusan hardware (longer rotor I think) free of charge and he said it will be everything I need to install the ignition properly. Moral of the story: Dynatek rocks! They get my full support and they should get yours too.

It may be a while because I'm leaving town for a bit, but I will update further when I get the new parts and install them.

Hey guys, it's been a while but I have an update. As I mentioned last time, I emailed Dynatek and explained my issue, they concluded that I bought the wrong ignition system and sent me the other ignition piece for free. That's right, it was my fault but they took the initiative to fix my mistake regardless. I got back in town to a package from dynatek with the correct advancer in it. I put it in and I now have a properly torqued advance assembly that still allows the rotor to rotate.

I set the timing to turn the test light on as soon as I fully twist the black rotor when the tick is on the rightmost mark. This also turns the test light on when I turn the motor to the F mark without twisting the rotor at all. I think I have the timing set properly now. Big thanks to all you guys who helped clear up my issues, and an even bigger thanks to Dynatek for being an awesome company to work with.

You might consider using an induction light to fine tune. Mine was still slightly off even though it was running good after static timing. Runs even better now

I plan on doing that once I get it running. I'm still struggling to get it to start and I can't figure out why right now

Hello all!!
I have not posted before, but have read through hundreds of posts seeking advice on my '81 GS850 GL. This forum has been a great help and I may have a tip that might be helpful to anyone installing a dyna s on their bike. My neighbor (retired engineer who until recently raced vintage bikes on dirt tracks) installed a dyna s electronic ignition on my bike. When it came time to static set the timing we followed the instructions and had 1/4 set quickly. 2/3, however was not so cooperative. after much trial and error we started over by aligning our sensors? 180 degrees and then setting the timing mark for 1/4. After that was aligned we turned the shaft to full advance while the other moved the plate until the test light came on. It worked, the bike fired up (after a bit of coaxing, it sat for a year waiting to be rescued) and smoothed out after it warmed up. It seems like a much less complicated way to achieve the same results. Maybe we were just lucky, or maybe we are on to something.
