If money isnt a big concern:
D&D TT kit
904 kit from TPUSA
Flat Slide carbs
Drop in fork kits
better MC (since its radial, you have a lot of options)
4 pot brake kit
upgraded rectifier (a most)
better clutch with green springs
personally, i Norman Hyde Ace Bars with good end mirrors.
Farley and Ace steering damper (ace part)
keep us updated
