You want a nice setup?
Grab that stuff from Adam, send the throttle bodies out to Pogue Machine for boring & adjustable pressure regulator and get Adam to sell you the cams from that 83 as well.
Swap the entire DFI harness. Seal the 81 head injector ports with pipe plugs. Add some K&N tapered filters.
You'll have a nice, strong running GPz11 that will stomp all over a BS34 equipped version
