I started this project with a stock 73 cb750:

Most of the design relies on Benji's body parts, including fork covers, headlight bracket, round tailsection and Trixie exhaust:

Fork covers/headlight bracket:

I've upgraded to 29mm Keihin carbs, Dyna electronic ignition and some Dunlop K-70s. I'm using a Cycle X top tree with xs650 gauges in a relocated ignition cluster with clip on handlebars:

Now that the rear end is back on the bike, I'll be installing the Trixie 4 into 4 exhaust:

Simple flush mount taillight in the rear seat cowl (3/4 view):

Micro LEDs for signals, flush mounted to headlight bucket and rear frame:

Paint will be dark gray candy over small silver flake with darker/black shading into knee cutouts and the bottom of the seat and tank which will have these emblems:

Still working on a cable activated remote master cylinder for front brake. Still debating between stock switches or simpler custom aftermarket ones.
I'll post further photos as things progress.
