My relative owns a Boss Hog, which has a small block Chevy for power! Talk about overkill!
But after owning a Valkyrie for a year I really like the flat motors. It really adds to the stability of the bike IMO.
So much for highway pegs on that beast. It looks okay for stability the way he was maneuvering it, but it's gotta be uncomfortable.
You'd think forced-air cooling wouldn't be enough for that engine, having been designed for fan cooling.
That clip of him hammering on it sure looked impressive from an acceleration standpoint. Hit it and HANG ON!
Well he has been riding it for 15 years without it needing a rebuild. Now if he has been riding it regularly, that is a testament to the design. You would have to put an oil cooler on that beast I would think. On the highway I bet it gets enough cooling, but in town and traffic I would like to see oil and head temps. But yeah most decent rebuilt corvair motors with a decent cam will have V rod level or greater power. And he said he shaved weight off in the switch.
I have seen people sticking VW flat fours in Dnepr and Urals over in Europe.
I had one, I didn't build it, but bought it unfinished and finished it off. A 1200cc VW doesn't have much more HP than the 650cc Ural, but torque was a different story - top gear wheelspin. The VW doesn't rev as high as a Ural engine, so top speed was down, and it was cruising at max rpm....nothing unusual for a VW. It had a much longer wheelbase to fit the VW engine in, but as it always pulled a sidecar that wasn't really a problem.
