Interesting Find

I bought this 1100 ish motor back end last year along with its blow thru set up and its sat in corner since  

Now with a planned shuffle round of motors into different bikes

yesterday after removing the 1216 oil boiler from Suzi "the blue efe"

i fitted it having Popped the clutch cover off to aid lifting it in so once in place thought lets see what ignition its got ... 

Looks like it has been run with an Oil Boiler ignition

wow that's a new one, never thought of that before. I wonder if it worked properly.

Yes it was running well apparently 

No reason why not really

I think you'll find that all the GS, GSX and GSXR engines (up to end of Oil cooled) used the same ignition base plate bolt pattern so as long as the plate / pick-ups / rotor and CDI match, all can be swapped around. Not an awful lot of benefits other than ease of sourcing spares!

one benefit would be that you would get rid of the mechanical advance on the early gs/gsx

True, but mechanical works and can be 'tuned' - go OEM electronic and you are stuck with whatever is programmed into the box ie a 13k redline on a GS850 won't be pretty!

That will make the old shafty squeak a bit for sure
