Every Dyna S rotor made for a vintage Honda I have seen has been larger in diameter than the stock rotor. Maybe in recent years this has changed. Are yours aluminum?

maybe their QC has gotten better, I don't know, But.....

Just for my sanity Mike, being English I have never worked in decimal inches or used a digital caliper with a readout like yours.

In your pictures the Dyna rotor has a smaller number shown than the stock, how does this make it larger?

Apologies in advance for being so dense!

Those were my pics, and yes, the dyna did measure just a hair smaller,
but for all practical purposes...
they are the same.

.8090 in. = 2.05486 cm.
.8095 in = 2.05613 cm.

so for us newbies..we can expect a "setting timing for dummies" post soon?
I was fortunate enough to find the magic wand online.

I just completed a how-to booklet.

So you have one of those! Cool! Kind of acts like the reticule on a scope, doesn't it.

put one of those sight glasses on mine in errr about 1978... put on a prestolite maybe a year later, and yes you have to set them correctly, but after that life is nice

Can anyone tell me if the early wing (1975-1977) stock ignition rotor that fits over the spark advancer is the the same as the ignition rotor for the 1978-1979 wings? Also If any one is willing to sell a 1975-1977 stock ignition rotor thats in good condition, please let me know, or if anyone knows where to find the rotor only, please contact me. Thanks, LARRY

The advancer is different. The round sleeve the lugs of the advancer engages on is part of that but I do not know if that is physically different than the later models.
