Here's a nice photo of the V8 engine.

Wow!
I see it the first time. Incredible! Thanks for posting.

Just awesome!  Look at the engineering and machine work.

[Yoshi823]

Found a few more pictures while trawling the 'net, including a few RCBs...









I love this next one...looks like a CB400F from a distance...


I hope that it's ok to show the next couple, as they seem similar to some others that have been posted before...


Lovely JapAuto...

And then to the RCBs...

Some real cool pics Yosh, the RCB is great but the 750 Bim with the gold wheels is to die for

This is my new favorite thread......I could spend all day looking at these bikes.

Any chance of seeing any of them in Daytona this March?

More racers from M3 Racing USA.

This one is the first version of the CR750 that we built and raced at M3 Racing. Pictured in Dick Man colors and ridden at Willow Springs, CA circa 1997, by editor of Riders Club magazine...my friend, Ken Nemoto of Japan.

This first pic shows Don Canet of Cycle World racing Dick Man special tribute bike at Daytona, where M3 Racing Team finished 1ST and 2ND.

Second photo is Gary Nixon on M3 CB750 Production bike winning Mid Ohio Superbike event.

G'day Cliff

All I have is a bit of history from around that era.

Boris Murray, ran a bike with two supercharged Triumph engines in the late 1960's and TC Christensen ran a similar sort of bike with two Norton engines in the mid 1970's.

Then there was the legendary Russ Collins.

He thought that if 2 was good, 3 was better so he built a drag bike with 3 supercharged Honda 750/4 engines.

This was the first bike to go under 7 seconds for the quarter in the world and it nearly killed Collins when it spat him off at over 170 MPH.

After months of recuperation in a wheelchair, Collins came back with a new bike.
 
A V8 engine made from two Honda 750/4 engines joined on a common crankcase.

The Sorcerer.

It became the first bike to exceed 200 mph (320 km/h)

At the same time as this Denco Engineering was building (with Boris Murray's help) a Kawasaki drag bike powered by 3 highly modified 750/3 two stroke engines.

This bike has survived and is now in Melbourne and still runs.

Here are links with some good photos and stories of Boris Murray and TC Christensen and also a link to the motorcycle Hall of Fame about Russ Collins.

If memory serves me, Russ Collins 3 motor machine Atchison, Topeka & Santa Fe (AT&SF) was actually an (A/Fuel) injected nitro run without any blower.
The Scorcerer (pictured reply #100) had 2 SOHC engines tied together in a V shape with a single modified GM blower feeding both, but they used individual crankcases.
The single crankcase/crank for 2 blocks was designed for Kawasaki KZ stuff by a fellow in the midwest. Russ never had an SOHC setup for one, but I don't remember if this was the basis for 'Battlestar', the rear engined bike. That was to use Goldwing type heads.
Russ didn't run in the 6's with either of those bikes, and 7.30 second/199.55 mph (I looked it up) was Scorcerer's best mph. Terry & Byron ran the first 200 at OCIR.
Russ did have some success with Bill Miller's (BME) Top Fuel car, qualifying at quite a few races. The Pomona blow over put an end to that.

You're 100% right about the AT&SF having no blower.
I always understood that the V8 was a single unit crankcase, but I'll be corrected if that isn't right.
Thanks

Some years back I saw an artical about Russ and that single crankcase/crank. A very fine piece.
It made me drool...
For several years I toyed with the idea of building a double engine bike, I even started a chassis; but instead went back on the road 4 wheel dragracing (as a crew guy) and sold my project as a roller...

Here's a CYCLE magazine i have from 1974 with RUSS COLLINS 3 engine injected dragbike on the cover.

And the best thing about that magazine Blue is that it was only 75 cents.
