Ignition upgrade question

[Towsejames]

I’ve noticed you can get a Dyna S ignition plate to replace the points as an upgrade to improve starting and smooth running.

I’ve also found a unit on David Silver spares. ADACA300505P this is the part number, it says this is a good quality Japanese part and sounds tempting at a good price. No extra parts needed.

Has anyone got any experience with either and can let me know if they’re worth getting?

My bike is completely standard at the moment running points. Cb550F 1976

Thank you

I have the full Dyna S kit with coils on my 400, it was recommended by my Brother-in-law.
Members here advise it does increase power consumption, I've not had any issues on that score.

On the 400 there are two types of electronic back plates listed by DS for the two different advancer brands as the lobe sections are a different fitting.

On my 500 I've kept normal points, it starts just as well as my 400, for me not worth the extra cost
I like the sound of the Boyer system that keeps the points with condensers disconnected iirc. I have no idea of cost or power consumption for Boyer system, someone here will know.
