Z1 to KZ

Will Z1 wheels fit on my KZ without too much modification? Basically what i want to knwo is if i'll have to space my sprocket, and if i'll ahve to make new spacers for the wheels themselves, and whether the axle diameters are the same.

Thanks
Tyler

On a KZ 650,You will probably have to do some mods to the wheels or spacers to make them fit.
I have Lester Z-1 mags on my 76 KZ 900 and the rear bolted in fine, but for the front I had to machine down the speedo drive to fit the later forks.
