I wish I'd bought an RZ back when I had the chance. But it's good to see some old guys tearing it up on some of these babies. There's still hope for the world.

To bad rake wrong fore triple trees and geometry start with tyre's the tire and wheel are a integral part of the vehicle refer to owners manual refer to qualafied service resourses found your problem two jugs cylinders two many can't find clymers manual go factory demand correct parts aka entire motorcycle

Ignition modules are the hard part pretty much still 750 just don't halve run higher rpm same range output less work looks like incorrect dated from 1970 where's Arlene nesses looking forward to v six by way similar square four less part's

Still have my Mach III.

Wrecked a great bike.

The racing version in 1979 - the H2R750 put out around 140bhp - so more than this 5 cylinder version.

Listen closely and you will hear a huracan

The Quack H2 was considered to be the Widow Maker and that was because of the blistering acceleration on the 750 but what the Hell kind of accelerating will a 1250 two stroke do? 😳👍

cette moto est une cochonnerie en comparaison de la 500 RG...

it was a hard day when i sold my Yamaha RZ350. but... i sold it to buy a V-Max! still, there were days when i missed the RZ350

Handel bars ,forks ,Chang out .

I can imagine, you like me, are very interested in recent developments in two-stroke technology that Yamaha is getting ready to introduce a new fuel-injected RD-350 two-stroke twin that complies with Euro 5 emissions for 2025. There is lots of expectation on how powerful and what features there will be, but I can bet it will be a real winner for Yamaha. My money is waiting.

I imagine that's a nervous kick start

The amazing thing is the tiny shed he builds his bikes in.

that guy creates some neat bikes

Yup. If the 750 was ‘the widowmaker’ this would be the…?

Very good video young fella, I’m so glad you got all the specs correct, so many others get it wrong. Thanks for the upload.

I wonder what the acceleration is like with an extra 500cc and its top speed?

My 12 y/o best friend lived with his Grandparents over a diner on the old highway ‘99 in 1969 and I’d sometimes stay over on the weekends and riding in this car felt like being in the Batmobile. Theirs was oxidized red with age but I didn’t care, it had a throaty sound and the radio sounded great.

Back to the future 2.0 now on a gamma 🤣🤣🤣🤣

Its literally v10

I owned a darkish green KAE 500 Mach I. It was very difficult to keep the front wheel down, ... in any gear. When I got on the freeway, I had to lean over the handlebars and push down to keep the front wheel on the ground, although, periodically, it still came up. You could tell by looking at the front wheel. The wheel would move so slow, that you could see the spokes individually as it slowly spun around. It was a death machine. I loved it ! It was awesome. Unfortunately, my eldest brother broke it down to frame and engine, and sold it off as scrap while I was attending college. What an incredible waste. I miss it very much.

Please tell us the 1/4 & top end~ 🙏

Nirvana, twilight zone gateway: dreams for years & love!😀😃😄😁😆😅🤣😂

What a lot of people dont realise is the sort of things that go on with a lot of this sort of stuff… 😮 it can be quite a surprise to many. Others focus on say curry and of course rock music naturally others go , ike whooahh lets have jerk chicken and some dub - but one thing we all got to say, I imagine is boy that sucker sound friggin’ GREAT 😊

Milliard is a genius but thus was sacrilege in my opinion. The H2 is gorgeous as is. As a testament to his abilities though it’s amazing.

I have a yamanha 1971 I would like find a inginition electronic to change you know what kind I can buy?

Milliard mainly makes show-off bikes that serve no practical purpose. Lets see him design an original motor instead of just welding a series of practical motors end to end until they are ungainly, unbalanced and ugly.

Nice ride had a 350 triple in 73 a five hundred triple in 76 an a750 in 78 ..yupp thise were the days

Last ditch 2 stroke effort out of Yamaha. It was built alongside the 4 cyl 4 stroke version. Which recieved ALL the better components (that the RZV Did not) Yamaha had seen the wall writings... ultimately the 4 stroker Proved the faster machine. And was the final nail in the 2 stroke Coffin.. at least for Yamaha mfg'd racer type Bikes.

the fans are to dry his hair,not cool the bike....

I can only imagine how bad this thing wants to kill you

The bikes in the 70s where and still are the best full stop 😊

He’s rich

He's brilliant, but, what's the point? It's heavy has no side clearance, slower than things the factor makes.

Looks like a straight-line demon, but more than a handful on corners - no road clearance when you crank it over.

Sadly Ford made the decision to enlarge the car, eliminate the frame, and install a 352 engine. I worked on these vehicles, overhauled the complete drive line. Like the saying goes they appeal to the emotion, however the heart of the vehicle is sick. No offence to you the rebuilder, you did an amazing job.👍👍👍

Since when did Gandalf run a dyno shop? 😂

Ты только на ходу так не слезь с мотика

Beautiful. 👍🏻

Nothing but envy 😢😢😢

Just wish he would do a bike program with out Henry Cole and get Sam involved be great that would instead of coles stupid remarks

Speed time is good for a car that weighs 6k lbs.

I do wonder what that cost.

I sure miss my H 2 after seeing this video. Sound and smell of a 2 stroke are unique.

Awesome TBird!

The most powerful in Europe claimed 59hp but in reality was 47hp. The YPVS valves on this bike are a weak point. The SAEC Suzuki from the same period is much more reliable.
