I know zero about snow mobiles, but the talent in this guy's machining and engineering is abundantly clear.

Men like this are treasures we need to hold on tight to, and soak up everything we can from them.

I’ve seen a lot of build’s. But this is way above anything else. I’m just floored on the time & smarts to build this sled. Had to skip to the end to hear it fun. But will run it back in the morning.

Man I love it! Call it intrigued. Nothing like sitting back quietly and listening/absorbing everything he says. That is the best about watching someone that did something one off.

Radial engines don't leak oil, they are just marking their territory.

This one won't. But just because a 2 stroke carries it's crank case oil in it's fuel.😂

This is what happens in Minnesota winters with 2 much time on our hands. Stunning build and creativity that defies the imagination. I saw 2 other Kawasaki’s hanging out…How can a person collect 5 Sno-pro cylinders, let alone 1? Ultimate garage tour stop, you guys rock!

Lived here my whole life and that math checks out. Seasonal depression will getcha if you aren't putting functional: suspension, a snowplow, lights, class 3 receiver hitch, and make your own lawnmower blades (with a changable curved lift blade on top, cutting blade on bottom at each end, made from S-7 tool steel @ __ rockwell, C scale) for your Hustler zero turn lawnmower...or solid aluminium baseball bats that hit basketballs out of sight, or spud launchers with a coil & sparkplug, or SO MANY KNIVES-alot made in the style of Rambo with 'retired' Cosin CNC cutoff saw blades, or used carbide insert knife sharpeners, or bike chain/impact drive ladder lift thats holds it tight to the ceiling or just keeping the fleet of beaters any of my 4 girls and wife drive (...very hard, I might add) keep me from curlin up in the fetal position and wimpering "I'm done". Others would whip up a 5 cyl. radial 2 stoke from scratch. Pretty sure it's why we've busted out Bobcats, water skiis, artificial hearts, floor scrubbers, stamping die cushions, the toaster, plus MANY MORE inventions. Make stuff or go nuts, that's our choice up here; simplified.

THAT'S FRICKIN' AWESOME!!! Thanks for sharing this awesome sled with 2 sled legends for all us to see Nutter!!! Race on!!!

Awesome video! I owned a few vintage Kawasaki sleds. The 4/6 LTD’s had duel plugs for each cylinder. My 82 LTD 440 with factory duel pipes/carbs……perfect example of engine technology being way to advanced for the chassis. Dang I miss that sled! If you google photos of 82 Kawasaki LTD snowmobile you’ll find my sled. Great video Nutter!

Quite the amazing build

Super cool and great group of brilliant humble dudes😊

By far, one of the most incredible 1 off hand built 2 stroke radial engines ever. this is one of the best snowmobile vids I've seen as well. There was one other time a guy brought his build out on a lake. I was ice fishing and heard a harley davidson vtwin fire up turned around, and sure enough, a snowmobile with a harley vtwin swap 🤯 seriously love this one though incredible build and craftsmanship the attention to detail and you installed some carbon fiber so 🤙🤙🤙🤙

As soon as you might think you might know something I come across a demonstration of engineering that humbles me

If you grenade the connecting rod on that engine you get out a large broom and sweep up the enormous amount of shrapnel. Then start all over again from scratch. What a remarkable feat of ingenius engineering though. That brilliant man most definitely knows his stuff. Wish us average sno-mo guys could afford a guy like that!

Nothing short of genius

Thank you, this is awesome.

Awesome fantastic work. A little correction though. Engines in a radial type configuration where the cylinders and block turn around the crankshaft are rotery not radial engines.

He needs to talk with Allen Milyard in England; they both are two peas in a pod when it comes to home engineering engines that have never been built. Allen builds motorcycle engines.

Know nothing about snow mobiles, but played with an aviation rotary engine, w-1820

What this man did cannot be done by AI. I doubt if he had a complete set of engineering drawings which are mote important for high volume production and complex products unfamiliar to those producing the components. He said he has been designing this in his head for 20 years. The design evolved. He just said “ no drawings”. “Scribbles”. I am a mechanical engineer and made things both ways. It more fun this way but this is a one off, but to do this in your head is amazing. This tool and die maker admits he thinks in 3 dimensions. That is another talent not easily developed if ever. I still work in 2D and throw the first 3 samples away resolving the 3rd dimension issues. My greatest respect to these craftsman. They don’t get the credit based on the talent they have because nobody really understands what he does except for engineers and other mechanics, technicians and tool makers. It’s amazing.

Very, very cool. Was it a Kawa, because that was just the sled you had to work with?

looks cool you might want to put a clutch cover on that thing i had one blow up once was not a good thing i am lucky to still have my face

Absolutely amazing I had a friend that had a Kawasaki intruder liquid 440.. As least as I remember it wasn’t that fast SRX or Merc snow twister would kill it…

How about an OP 1700 2 stroke made from 2 850 Rotax turbo R engines like this 2 stroke OP Cummins. mart.cummins.com/imagelibrary/data/assetfiles/0058689.pdf

The main reason radials have an odd number of cylinders is because most of them are 4 stroke so the firing order then skips every other cylinder so after all the odd cylinders fire it naturally skips number one and starts firing the even cylinders because the number one cylinder is next to the highest number odd cylinder. having an even number of cylinders means it would have to skip an extra cylinder when switching back and forth from the odds to the evens causing the harmonic imbalance.

@nuttersspeedshop

4 ай бұрын

That makes sense. Thanks.

I dont sled and I dont build engines... but this is fascinating.

Thats how all radials work.. they all have a common cranking point.. other than the ones that put their power out like a 3 phase motor.. those run like those old tank engines..

God damn genius

Good idea but the two stroke radial has been around for years, especially in the model airplane industry . If I remember correctly, Cox made a 3cyl, a 5 cyl, may a 9 cyl also . other companies aslo made 2 stroke radials They really are very simple, much simpler than the PW R1820 in the Tracker(CP121 Tracker) But it is impressive that he made one that big from scratch, good job

One machinest to another,cudos👍

Only thing that would make it more epic would be kx 500 power valve cylinders..2.5L 2 stroke would spinn a big prop.

Would love to have one for a motorcycle build I am working on

That is way cool

Nothing like the smell of Castrol R

How / where is the vertical crankshft rotating the horizontal output shaft to primary? A motorcycle pinnion / hypoid?

I believe Paul said it was an industrial gear box. It has a 90 degree turn and it runs in gear oil. That's all I know for sure. Paul says it is big enough for the job. It's pretty hidden inside the chassis and under the engine.

That’s crazy.

Want to see it run in the snow

I’ve seen some crazy things. This is right up there with everything crazy I’ve seen. Someone attached an airplane engine to a sled. EDIT: I did not know Kawasaki made airplane parts, I saw the radial engine and my thought went straight to airplane engine.

Cool Kool Cool

this beautiful engine should be adapted to light aircraft !!!

Is this the sled that was at St Germain a couple years ago?

@nuttersspeedshop

Yes. I think I even recall it running there once.

Kawasaki didn't crush all of them, there's a couple in a salvage yard in Mt. Pleasant, MI.

Those cylinders look like the cylinders on the 1980 81 Kawasaki invader 550 I had two of them over the years

Don't know about snow stuff but that could make a fun murder cycle engine 👍
