Kinda looks like an early Gold Wing with that horizontally opposed motor hanging out there. The bike looked to have a similar "flywheel effect" causing the bike to rock from right to left when you give it the gas, like the Boss Hoss' do.

 

Amazing what you can do with a little ingenuity and some left over parts.

 

May be one way to go back carbureted, the thing even sounds good!

Did the WWII Harleys,"Military Harleys" have 180 opposed cylinders? Not as many but the German BMW and Harley war bikes had those cylinder heads sticking out in the wind!

May just have figured out how to cool down the Harley's

Nah! It'll never catch on....

 

yes, Harley made an opposed motor

 

Did not look like it took much to kick it over. I have seen HD's that took more effort.

Neat conversion.

 

These engines are alive and well. Since they have a following in the experimental airplane hobby there are both rebuilt engines and parts available. In some cases there has been some tuning done as well but the reverse of street mods since the airplane application needs low RPM power unless geared down it is limited to the 2600-3400 RPM range due to propeller tip speeds going supersonic/less efficient.

From a website (below) that is arguably the expert:
The Corvair engine is a 164 cubic inch (2,700cc), horizontally-opposed, six-cylinder, air-cooled power plant. General Motors produced 1.7 million Corvairs between 1960 and 1969. All of these high quality engines have hydraulic lifters, torsional vibration dampeners, full flow oil systems, spin on oil filters, and aluminum cases and cylinder heads.

Google yields a BUNCH of info and you can start here:

Hotrodders at work in about the reverse of us....they need power down low...torque peak is way down the rev range. The stock street Corvair was available up to 180 HP at 5500 ( I think) when turbocharged and 140 NA. This is a way cool idea...can be 3100 CC and still fits in a Harley. Parts on the cheap too comparatively speaking. For instance VW jugs can fit, lifters $2.00

I would like to read more about the actual swap and see just how doable it would be by the average Harley wrencher. Almost wish I hadn't seen this thread....my brain is already fried trying NOT to do an LS engine in the built Miata I drive for groceries. John

 

He posted the video himself on youtube. You could prob get a hold of him thru there

 

that is astounding , where do you find this stuff ? lol
i sent this to a buddy of mine that loves and has a corvair , and has an old sporty project going on. I might be about to stir some trouble lol

 

That is awesome! Gold Wingers beware!

Never thought olive Drab green could look so cool, this thing could kill the chrome aftermarket. Ratrodish, no frills, solid wheels! Probably worth a cool fortune now if you could find one.

I wonder why Harley dropped this Style Engine, any problems crop up that made this configuration obsolete? I think the V-Twin definately looks better but for cooling purposes this configuration looks more efficient.

Probably the reason I ride a Harley instead of a BMW! Lets face it, it's all about the look.
