A shameless image thread for the enginephiles

Since we're pondering engines with more than 4 valves/cyl, here's the 8 valve/cyl Honda oval-piston engine. Yes, it's kind of a cheater for purposes of this discussion because each combustion chamber is a pair of 4 valve/cyl combustion chambers siamesed together. But these devious methods are precisely why this engine is so epic.
I remember this! It was on NR750 and 125 HP from that displacement was kinda big deal in 1992.
Hardly.. unless..if by epic, you mean epic fail.. & Yamaha had a 125hp 750 on test - in 1972..

It was a 500, not a 750.

The NR750 wasn't build for power, it was a proof of concept for the oval piston engine used in the early eighties in the 500cc championship. Looking at the bike it was more that just the oval piston, the whole design was far ahead of its time. The bike was vapourware for years, nicknamed the NeverReady. The modern equivalent might be the Honda RCV road bike. Not the power you'd expect but technically such an interesting concept. Even Honda's RC30 and Yamaha's OV-01 had more power half a decade before.

I did not write 'epic' i wrote 'kinda' - as it was totaly new architecture and the engine from the get-go was at (or near) the top for that displacement (not talking racing bikes here or something that was on test bench). The biggest fail on that engine (IMHO) was that it was too heavy.

And, please tell me as I was driving lot of bikes at a time and cannot remember myself, which bike that was sold that year made 125 hp from 750 ccm in 1992 'epic fail'?

Others may have but I had never heard of Henry playing with this....
Image
One of Henry Ford’s odder inventions—and one that certainly challenges the notion he only ever wanted to build Model Ts into perpetuity—
Ford’s interests in the X-shape engine, which essentially uses two 90-degree V-8s V-4s turned on their side and mated on a common crankshaft, dated to about 1920, when he filed for his first patent on the design, noting its compactness, relatively high power-to-weight ratio, and suitability for air-cooling as its advantages. Indeed, according to The Henry Ford’s page on the X-8 in its collections, pictured above, it measures just 17-inches wide, 17-inches tall, and 14-inches deep.

The L-head example above, however, is far from the only X-8 engine configuration Ford experimented with. As pointed out in a 1973 Special Interest Autos article, it was one of seven experimental X-8 engines—and 58 experimental engines total—once left to sit in a sugar beet mill building on the Greenfield Village campus. While records for the experimental engines were incomplete, the seven X-8 engines include both air-cooled and water-cooled L-heads as well as at least one aluminum air-cooled overhead-camshaft version.
Ford might have conceived the X-8 concept, but he trusted development of the engine to Eugene Farkas, who worked on it for the next six or seven years, until it became evident to those surrounding Ford—and eventually to Ford himself—that the X-8 would never replace the Model T’s four-cylinder engine (due in no small part to reports that the lower spark plugs fouled often). Ford instead turned his attention to developing an inexpensive V-8 and abandoned the X-8 altogether.

Cool. Flip it on it's side, crankshaft pointing up. Flat engine without space restricted headers/runners.

I'd rather set it in line with the rear axle (second throught: slightly forward to get the trans & diff above it) for a compact setup and low COG.

120/hp from a 750 was about the going rate back in '92, and 140/hp from the litre bikes.
but 125/hp from a 750 production bike, I don't remember Yamaha doing that. What motor did they use?

My thoughts exactly, it's just a carbon tube with an air filter attached.

That's the air intake. The "intercooler" is (isn't) the piece of aluminium tube running across the engine bay in front of the engine.
