Dyna S DS3-1 Doesn't Fit?

[Guest]

Hello everyone,

I ordered a Dyna S -- DS3-1 for my 1980 GS 550L
Today I tried to install it but found that it won't fit.
My issue is that the Dyna has the two black pickups on it, and on those pickups are two black rectangles that protrude slightly.
I checked the info on the link I found when I was searching the forum

My ignition system looks like the second photo but my rotor doesn't look like that, instead mine has two lobes, one on each side opposite eachother. One side is bare, the other has two little strips which I assume are the magnets to transmit the signal.

Anyone else run into this problem? I bought the bike AS IS, it was not running.

I just noticed in the kit there is part that looks like a replacement rotor. Is that what I'm doing wrong?

Not sure what setup your bike has, but I know the dyna s needs the old style mechanical advance unit, as opposed to the electronic advance on later bikes. Not sure if thats your issue, just a thought, hope it helps!
good luck and welcome to the GSR! You are in the right place.

Yup, install the new rotor.

don't know if it will be any help, but when I upgraded my '77 550 with Dyna S, I made a short description with pictures: http://www.poulzen.dk/Upgrade%20to%2...20ignition.pdf

at least it shows some pictures of the rotor setup.

The Dyna Rotor has no protrusions on it at all.... You need to connect it to the old advance unit. You may need to make a little spacer for the end. I used Nylon washers (you may have got an Aluminum one in your box but I didn't)

Yeah that's totally the issue. Thanks for the link, I definitely will use that as a reference if I get hung up. The problem is my brother took back the garage, so now I'm in the shed. Usually I would lay all the parts from the kit out on the floor and then start, but there's no room out there. So let that be a lesson to everyone, always look at what's in the box and make sure it's all there

Thanks again everyone, with the new battery and the Dyna stuff going on later today, I should have her running for the first time this afternoon.
