Mechanical advancer differences

I have two z1 engines one a z1b and the other a z1. I see that there is a difference between the two advancers in how they are stamped (timing marks). I have a new dyna ignition setup in the z1b and want to put it on the z1. I know that according to z1E they have a different rotor for the earlier engines available. Is there a reason I can't change the whole setup between the two (including advancers)? I think it should work, but I thought I would throw it our there here just incase.

The later style advancer is a better unit in that it gives a better spark curve at the bottom. If you change the whole setup you should be fine but if you use the earlier advancer I would recommend the optional rotor that Z1E has available.

Well if the timing marks are located in different areas of the backing plates of the advancers,I would definitely install the one that gave you a proper reading in relation to piston location.

Per Z1E:
Dyna-S Electronic Ignition DS2-1 - Kawasaki Z1 KZ900 KZ1000...
If you have a 73 Z1 or an early 74 Z1A, we may need to supply a different crank rotor. Up through engine number Z1F-32817 kawasaki installed a 5/40 degree mechanical advancer (normal fire mark is 5 degrees then advancing to 40 degrees). If you have one of these on your engine, please enter a note in the special instructions to replace the standard rotor (3 rotor) in the Dyna-S with one special for these early bikes (3A rotor).)
As many advancers have been swapped from bike to bike, please check before ordering.

I interpret this to mean using Dyna-S with the early advancer requires Dyna-S rotor 3A,
and using Dyna-S with the later advancer requires Dyna-S rotor 3 which is furnished unless rotor 3A is specially requested.

Sorry I don't know difference in appearance between rotor 3 and rotor 3A.

The Z1B should have the later advancer and rotor 3, which I believe would fit and work just fine on the Z1.

Good Fortune!

Those are the two units I am talking about right there. I only have the latter style dyna parts. Sounds like it is a go. Thanks for the replies.
