Dyna S on CB 450 I'm stuck

[cardinal]

Anyone put a Dyna Ignition on a CB450? I am trying to figure out how to do this, but am finding zero videos or walkthroughs on it. The main problem (for now) is that the plate won't even fit in the spot that it needs to. It hits the bolt on the right. I could notch the plate, but I have no idea what the orientation that it needs to be at is. I was told this was the right ignition for this bike, but maybe it's not?

remove that bolt, fit plate and use it to hold the plate in?

 

[cardinal]

That could work. I think I'll flatten the washer on that side and put it back in there. Now, I have no idea what the orientation of the unit is supposed to be. I've seen other ignitions that have windows to see the engine orientation and that allow some degree of fine-tuning to get everything to line up. Is there anyone out there with one of these installed? Maybe this should be posted in a more general forum?

Set the motor to the TDC timing marks on the crank and then see where the ignition has to fit. They fire on the leading edge of the magnet. That will get you close enough to set the real firing point.

You will probably have to notch the backing plate to clear the rocker adjusting nut.

It should orient the sensors to where the cam would open the points. I know the dyna instruction sheefs leave a lot to be deisred. I got lucky as the GL has a good section on another forum with full instructions and pics. Hopefully someone with a 450 can chime in exactly what you need.

Thanks for the help. I reached out to the OP of that thread. It's old, but maybe I'll get a reply

Did you take off the alternator cover to see the timing marks?

UPDATE! I got an email response from Rodrick Smith and he shared a pdf of his install guidance for the Dyna ignition. It has been very useful. I am still trying to figure out how to time this thing now that I have it set up, but I think once I do, I'll make a video to share the process. It looks like the pdf is too large to attach here

Here's a dumb question: Both of the coils on my bike have blue wires (neither one has a yellow) Will the coils behave the way they need to if I'm using two of the same (in this case right side) coils?

 

[cardinal]

Ah! I figured it out! I thought I was crazy because it seemed like the coils were firing the wrong side, but then I realized that I had them wired incorrectly (this bike is an assembly of pieces and a lot of it is stuff that I didn't do), switched them and now it is set up perfectly. I am going to shoot a video and will post a link here when complete.

 

[Maritime]

Ha, nothing like figuring out PO wiring!

 

[cardinal]

So, one more question: I tried starting the bike today after double checking wiring, adjusting the cam chain and valve clearances and it is turning over, but there is no fire happening. I timed the ignition by rotating the motor to the F position and making sure the ignition is connecting at that moment without advancing the pickup at all. Is this right? I've been watching a lot of electronic ignition set up videos on YouTube, but none are this bike and so they are all a little different. Should I be advancing the pickup? Should I be shooting for TDC?
