Handlebar Setup

I decided to go with drag bars, partly because they're comfortable on my wrecked wrists.

7/8" dog bones proved hard to find.  I was about to bite the bullet and pick up some 1" repops and shims, when an old 7/8" set popped up on ebay, minus two of the caps.  Some CB77 handlebar clamps worked out with a bit of filing.

The Doherty levers required that I replace the nipples on my Honda cable with these brass British pieces.

Eventually I'll ditch my Honda risers and the riser bar in favour of a one-piece system with threaded bungs welded onto the riser bar.

Engine

The engine was a mess.  The crank's main journals were peeling, and the valvetrain - especially the rocker arms - was junk.  I ended up having to find a crank, its needle bearings, and a complete head, as well as the usual consumables.

Current Mock-Up

This is the latest mock-up of my CB450 project since replacing the backbone with thicker-walled, smaller-diameter tubing to fit the Wassell tank.

A couple of frame braces still need to be added, along with some tabs for the side covers, before smoothing and spraying the frame, and beginning assembly.

The headlight needs a proper mount and the fender will probably be replaced with something that doesn't look so goofy.  The front end will eventually be eventually be swapped out for a CB77 front end and 21" rim laced to a CB77 hub.
