Cyclone Motor Photo

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

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

[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!

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

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

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.

i dont remember this cyclone being at the chandler auction. i dont know if its the only one with a sidecar or not. i thought lattin had one???

[c.o.]

After continuing to study pics in Steve Wrights "American Racer" I thought I'd just shoot him an e-mail and see what he thought on the "blue" subject. Here's what he had to say...... "I am sure they had a dark blue paint option, I have had a look for info, but no luck yet. It would seem that an alternative to their Chrome Yellow would be logical as it would not appeal to everyone, why lose a sale due to a simple option of paint choice?" As you can see there's still speculation but he's diggin' for info. Maybe we'll hear word on this yet!

Classic Bike / February 1985 / McQueen's Machines

$20,500 was not unreal . . .

Thanks Jurassic!

Not a bad looking sidecar rig at all ,and it looks like it get's used a bit to
I am a bit curious, but what are the chances that the cyclone emblem was applied to the top of the nose of the sidecar and not the sides?
Would that be a Rodgers sidecar given the time line of the bike?

Mcqueen's Cyclone

Here's a close up. of the "spy"

The "spy" looks like he could be Lacy Crolius, but I'm not sure that Crolius was this tall. Wish we could see his eyes better. Unless like Chris said, he's a spy for Indian in disguise.

I'm pretty sure Barry's Milwaukee stamped photo is from the June 20, 1915 race. A 100 mile event I believe.

There were only 3 races in Milwaukee in 1915 (not 4 like they promised) and the dates were changed, but only the June 20 race seems to fit the bill. On May 2 it was reported that Carl Escherich was negotiating with the Joerns people in St. Paul for quote: "a fast yellow devil Cyclone." Promos for the June 20 race promised that Carl Goudy (also in this photo) and Bob Perry would attend. The Aug. 1 and Sept. 19 races do not say that or mention them. Besides, on 18 Sept., Goudy was at a race in Rhode Island. Unlikely he was in Milwaukee to race the very next day.

If someone has the June 20 race results in some period mag, that would probably tell the tale. My info all comes from the Milwaukee Journal and is not complete. They didn't publish complete results, sometimes not at all if the race was on a Sunday (no Sunday edition).

Too bad the photos isn't of the Aug. 1 Milwaukee race. A machine called the "Rowell Special" was entered. This was described as a "dark horse" entry. Frederick Rowell was an engineer at A. O. Smith at this time and Perry Mack also worked there. Dick knows about this. Unless this was a Smith Motor Wheel in a 100 mile race against Harleys, Excelsiors, Indians, etc. it had to be some top notch one-off racing job.

Possibly with a Perry E. Mack OHV motor?

I wonder if results of the Aug. 1 race in period mags mention the "Rowell Special?" It would be very cool to find out and learn what this bike might have been.
