I know you aren't really after a trike, but this might stimulate your imagination. Especially the front wheel setup.

That's a work of art.

Pete, I don't think the imagination needs stimulating; it's more the work ethic that needs some stimulation.

It looks a bit like a three wheeled dragster.

Love the nav light on the 'wing'- which is a formed part of the rocker cover.

Now you are talking. How about another Australian motor - three cylinder radial - 200hp/litre. Presently 2 litre. When fitted to VW / Porsch they claim it doesn't sit closer to ground than the old flat 4. And the note!!

And there is a Aussie 3 cyl radial powered bike under construction - all you need is a sidecar for the farm!

And not to forget Allan Millyard's five litre Pratt and Whitney v-twin. Also American Al Hackel's custom chopper with a single pot from a Wright R975.

I've often thought of doing something with the R-670 jug that I have. It's in good condition with the valves, rocker gear and rocker covers. I just wish I had two of them, it would make a great three litre v-twin. A nice pot with a lot of character. I've also got a couple of Cyclone 9 pots but they're huge and ugly, much like the Millyard P & W's, so they'll remain as paperweights. Just for a laugh I lined the R-670 pot up in the M-63 Ural frame the other day and it took up most of the available engine space, no room at all for a bottom end.

Kickstarting Al Hackel's 1700cc Wright thumper:

They're handy people in a workshop. Al Hackel built most of the motor himself but I think he might have got somebody else to grind the cams. Allan Millyard delves fairly deep into it; he even makes his own carburettors at times.
