The intake system may also have a constant velocity devise off the rear cylinder where some type of "vacuum tube" is attached from the intake valve pocket to the intake manifold, the operator appears to be tuning the motor here. EVEN COOLER

I've allways been a fan of the in-line 4, but that has to be right up there with the Brough Superior in the looks department. They sure knew how to make a machine pleasing to the eye in the old days, beautiful piece of workmanship there, wow!

[Slojo]

I didn't get a good enough look at the intake valve actuation, thinking there's another invisible rocker somewhere, or there's a valve stem like I've never seen before. .... sure got a dog-leg for a push rod. But the bike's beautiful!

Vincent's have a peculiar valve mechanism where the rocker operates the valve below the spring. This motor may be similar, it is a unique pocket valve machine. I would like to study it more to better understand it. I thought Henderson was out of line with its out of line intake pushrods, this motor is way out of line with its wild offset push rods.
Basically they way I see it is it is four singles attached together with one crankcase.
WAY COOL.

Sorry guys you have missed it entirely. This most facinating motorcycle puts to sham an Ariel square four, it has four count them four crankshafts. Look at the bearing bosses on each side of the engine cases and then look at the split line of the engine case. It does not use a bevel gear for either the magneto or power output drive. The cranks all four roll into the wind not screw into the wind two forward two backward. This bike is my all time favorite four I have just decided. How can it get any better? A four that does not have torque reaction and includes a leather belt drive. Now how do I get one? Trades anyone?

Fantastic! Where was this meet at?

[c.o.]

Glad you fellas enjoyed the video! I crave this kind of stuff. I gotta get on the other side of the "pond" one day!! I have seen the clip of the white four cylinder and it just may have been posted on this forum before but for the life of me I can't recall where.

[Slojo]

Cory
You have out done yourself with this rare video find. Fantastic.

Or is it a Riley

Barry, think that 4cyl is the Lurquin Coudert 1905 listed at the end of film, there is footage of that bike being ridden on youtube somewhere, cannot remember where the link for it was

The decal on the all white four looks like a Riley Decal? I may be wrong. In any event old iron with pedal cranks and leather belts always make me smile. Nothing like running a belt bike down the road.
