If you're getting rid of the headlight, and the visor is for a 7" lamp, I'll take it off your hands. I'm pretty sure the KZs use the same size headlights as ours...
I'll say that, if you do hard-tail it, don't do struts (like one of the pics I posted). I feel like that bike would look just as good with black shocks, and ride considerably better. If you want a hard-tail, great, they're really cool, but at least get the crisp lines that come with it. Plus, I like how open the rear of the bike looks when it's been chopped.
But that's just my opinion, whatever it's worth. Budget, above all else, will probably decide your mod options.
