@@QuidamDePopulo Progress was stopped by green thinking. What else could you expect. I'm sad, that this technology was not allowed to goo any further than that. Very old times. It's similar with piston aircraft engines, but for different reasons. No green color there, but technology was astonishing.

And Suzuki had a 50cc triple the RP68 with 19.1 hp (382hp/litre) at 20,000rpm using 14 gears !

@@neilparnell5712 Yes, but it never raced.

A 350cc engine only has about 21 cubic inches. If your number of 4hp per cubic inch is correct, then a 350cc engine could produce 84hp.

@@yodasbff3395 You misread my 350ci as 350cc... but your math is correct.

It's pretty impressive, at 34 HP with 125cc that would make my ZX-6R produce 173HP (significant improvement over it's stock California emission compliant 134HP). I'm still just amazed how close we get with fewer cylinders and mass produced CHEAP machines that reliably do 50k-100k miles while doing wheelies and very little maintenance. Could you imagine them trying to get 7,500 miles per oil change? They probably have to do a teardown by then! This is almost the exact bike engine I'm wanting to build for my other motorcycle, I was going to make an inline 4 100cc 2 stroke (slap 4x 25cc weedwhackers together), that way it sounds like I'm screaming down the road but without speeding lol!

@@jakegarrett8109 could u imagine anyone actually waiting to do oil change at 7.5k miles? Oh yeah, that's u! 🤣

@@shawnsatterlee6035 I'm not sure when I'll do the oil change, I've got an oil lab kit I'll have sent off at some point so I can see how much contaminants it has in it. That's really the only way to know for sure is to test it and see how many ppm of metals etc it tests at. My car I do every 2k miles, but I don't know how often you ACTUALLY need to change sportbike engine oil besides what it says in the manual. Its about $48 in oil alone (plus filter and time), then crank the oil filter to 13 ft*lb of torque (I have my own custom filter socket adaptor for my torque wrench) and its not that bad. So far with 1500 miles after first oil change the oil in the sight glass still looks pretty new (I'm using synthetic oils), but I prefer to do more maintenance than the manuals call for because I want things to last.

naaah i like the straight to the point video now..

Check the piston speed!

Very short stroke.

The wonders and beauty of mechanical engineering

that's the ultimate flex

Proceeds to show it at 11,000 rpm and responding to throttle input

@@francislutz8027 maybe he meant 1700 rpm ? which is high but nothing crazy especially for a race bike

​@@madwarrior3771nope, 17,000 rpm

​@@francislutz8027maybe the throttle has a lot of play despite the stable idle point being so high

Historical info on Honda as a whole is almost always fascinating

Guess what? There is a new video scheduled in a two week time that is going to be about the V10 Verado

@@VisioRacer 👍

That's what freaked me out. Those guys are racing on those skinny treads? Ye gods.

Ďakujem a pozdravujem 🤚🏻

Thank you!

the ancient technology using secret recipe of 13 herbs and spices calculated with an abacus mustve been lost..

You can, it's just probably more than they wanted to spend. Also interestingly I've seen some carbon fiber designs that look awesome, though carbon fiber sucks in compression so I don't know how they are being successful without making duel connecting rod boxer engines. Modern technology we can 3d print titanium parts hollow, once I get my metal 3d printer I can do some cool engine designs and one of my bikes will surely be a rotary just like my car.

Besides the CB350 having some terrible issues with it's oiling system (disintegrates with age, my dad's rebuild 2 of them for oil system failure), then it's not too bad for that engine I don't think. My bike runs 7k rpm just below 70 mph but it sounds happy at 14k to 15k rpm cruising around (will go up to 16k rpm at 152'ish mph, but it needs taller gearing to achieve max speed). Some engines though can't handle much, my last bike I had screaming at 10k rpm (redline is about 8,500 and I thought it had a limiter... It did not, and I found out the hard way). So depends on the engine. Most I've revved an engine to was 18-19k rpm on a 2 stroke grass trimmer engine going downhill at 42-43 mph (12k rpm roughly at 28 mph), so it was way over-sped, but I didn't see any cylinder or piston wear and everything looked fine. So keep them below redline, they may not last long at limit speeds but engines can be replaced.

In the dame example, you can found the 6 cylinder in line of Guy Coulon that hé create himself!

I doubt that is easily attainable information if even possible. Besides, its not just the cam timing, but the engine inertia, flywheel and these things that make it unable to idle by itself

And later became the 2 stroke master actually!

yep....me

I do believe it was only 300cc's, but competed in the 350cc class.

@@fredtracy3931 You are correct!😉

@@danw1955 cool, a VW bus Mystery Machine! 👍

Yes, maby it was so 👍🏻😎🤘🏻🏁

@@mariusfridlund55 it was the Honda RC 174 riden by Mike Hailwood.

They still make the fireblade 1000 RRRRRRR double R (Arg! Me pirate edition!). It's still one of the fastest production bikes that's road legal. They are also known for dependability, so that's not a bad reputation. He might be more impressed with Kawasaki pushing boundaries a bit more with things like supercharged production motorcycles, but emissions kind of ruin what you can achieve, they didn't have much emission regulation back then

They did use Japanese riders, but the factories usually went for established riders from Europe and other countries as well. In the 1963 250 IOM TT Fumio Ito riding a works Yamaha twin came second to Jim Redman on a works Honda 4. But for a catastrophic pit stop of over 40 seconds, Ito would have won the race and become the first Japanese rider to win a TT.

Absolutely not

Pretty dumb request

The 1978 Honda CBX 1000/6 was a directly derived from the GP bikes of this era and was actually designed by Shoichiro Irimajiri, the same engineer who gave us the 50/2, 125/5, and 250/6.

@@CaptHollister I had three CBX's. They were awful as motorcycles, and nothing similar was ever raced. They had split rods and solid cranks, etc.

@@UncleKennysPlace CBX's were raced in production endurance races in New Zealand and Australia. I personally witnessed several of them exploding on the track at the Castrol 6 Hour in NZ.

@ktkace that's not how that works.
