Re: Head job
Not to mention, an overhead cam, and six cylinders. When I see something like this, I have to wonder how correct the rest of the story is.
Reminds me of the time me and a buddy took this old Willis-Knight sleeve-valve motor, and filled up one of the ports with JB weld. This optimized the compression ratio, and brought the brake effective mean ration pressure (on the Borgward scale) up from 2850 to over 3000! Yikes! We had to retard the throttle dashpot at full chat, down to something like 2700. That's ok, when running a Bernie Bergmann wet-dry timer (Ruxel @1.10 x .002646).

Re: Freakin Bike Fringe!
Actually, this design culminated in the "Vauxhall-Diablo" design, of the late teens.
It used a panhard rod/split-tooth knuckle arrangement, that aligned the centre cylinder(s) with the crank-pin, and the pre-requisite babit coated (oblong) caster/shoe assembly.
Some of these were "monosoupape" in design, and frequently caught fire. A simple modificaiton fixed the problem, but by that time, the design had become obsolete, and was dropped in favour of the Sussmann principal.
