hi guys, a sensible question from me, i could do with a proper answer, but also welcome as many daft comments as you can give.
these dyna s ignitions, are they universal, would the z900/1000 dyna s fit a gs 550

I'm not buying a gs,

i just need to know, not that there is anything wrong with the gs range, I've had a couple in the past. its just a question, thanks to one and all.
