Cyclone production numbers

[HarleyCreation]

Here's a new mystery for you guys.

Years ago I found mention of two bikes registered in Minnesota in 1913 named "Vortex."

What the heck was that job?

The name Cyclone and Vortex describe more-or-less the same natural phenomenon and the year is so close to the fabled Cyclone I have long wondered if there was a connection.

The second photo showing statnekov's cyclone there is the top portion of a sidecar shown is it rigged to a cyclone by chance?
I see yellow paint on a rear fender rack any chance you could post the photo of the lower half showing the bike and sidecar
Thanks Chuck

Mini '47 Knuck

Not to hijack this thread, but after seeing Jurasic's scale engine this morning, I just happened to come across this baby Knuck while looking for something else.

Well, no luck getting a link directly to the knuck page, but the address above will get you to the main site, and the name of the Knuck engine builder is Kieffer. There is so much outstanding stuff to see on this site you will be amazed.

Don't know why I can't get any links to work. cyrilhuzeblog.com or this one

[Looks like "Desmotronic" valve activation long before Ducati claimed it].

Desmodromic valve actuation goes back in theory to the date of the Strand Motor but they never tried that system. Ducati did not adopt it until the late '60s and never claimed to have invented it. Mercedes Benz used it on Formula One engines. Other tried it much earlier.
The vlves in a Desmo system are opened AND CLOSED by the rocker arms. Unlike the stirrup affair on the Strand which only opens the valves and the springs close them.

What a labor of love this little gem is. You're lucky to have one jurassic!

That has to be a nice conversation piece on your desk Jurassic how does it sound?

What a fabulous but expensive-to-produce way of doing things. The only shaft missing is one to the rear wheel.

Scaled engine

Oh my! I would say that your scaled Cyclone motor was a toy I would have found room for.

Make a youtube video when its running if or when there is time.

Cyclones around

Regarding who have Cyclones, from looking at his blog there seems to be one in Jeff Deckers position too.

nice repop???

[jurassic]

Daniel Statnekov had two, one blue and one yellow. Otis Chandler had a yellow road model also that had a sidecar affixed. That's Lane's in the photo. That's three road models I know of and five racers. I also know of at least three loose motors. We're close to a dozen. Hard to believe they only made that many. But how many real eight valve Indians, eight valve Harleys, or DAH's were built.

recently urban hirsch had his racer put back to a road model .i saw it a few weeks ago.its nice. does that makes 4 road models?
