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

[@S650Hero]

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

[@nicolec7290]

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.

[@darcy32171]

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.

[@jonmulack4226]

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!

[@jasonaldenhaley1]

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.

[@Z-Bart]

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

[@rowanerasmus-bc6sz]

Yep

[@Idrinklight44]

I know Wright 1820 really drink the stuff.!

[@jnljnl8485]

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

[@fastrat37]

WOW! I am amazed at his workmanship and glued to the video!! Thank you!!

[@itsbob2609]

Just wow! This is a video that so conflicted me. On one hand…I wanted to get to the end or whenever they fire it up. On the other hand…was so interesting that I wanted it to last for hours. What an interesting absolutely intelligent man. Great video.

[@husseinesmailzadeh9132]

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

[@nuttersspeedshop]

Thanks Huss!

[@air-1579]

Two Strokes and beer, Life is Good

[@freddy7700]

Great Deal. Congrats Paul. Absolutely awsome. RESPECT Bud. Thx for posting.

[@alaskarailroad3996]

Thanks for the video John. Paul is an amazing person.

[@JessBottom-m5i]

WOW! just WOW! beyond words.

[@davida1hiwaaynet]

What an amazing engine! He is a true artisan. Thanks for sharing your thoughts and build story.

[@nuttersspeedshop]

Thanks for watching!

[@Seasidelive]

Engine building pasion work is a thing of machining art. thanks for this video awesome

[@nuttersspeedshop]

It really is!

[@alotl1kevegas860]

What a beautiful piece of machinery. Top notch work 👌 I enjoyed the history lesson as well.

[@goopygeiger5632]

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!

[@nuttersspeedshop]

Thanks!

[@RalpherRalpher]

I had an 82 LTD for years and that motor definitely was quite advanced! I remember ripping down frozen Sodus Bay at 80+ mph listening to her wail at 8300 rpm!

[@jrhalverson1280]

All I can say is wow!

[@nicolec7290]

Love to see the build

[@timrussell1559]

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!

[@lloydscibe3849]

Thanks for doing Paul's build! He is a genus and has built amazing things through his career. Cool about the Kawi Sno Pro parts😃

[@nuttersspeedshop]

Paul is the Burt Munro of Snow!

[@rodbrezinski8033]

Awesome build great job

[@hardtail-gy8dk]

Super cool and great group of brilliant humble dudes😊

[@metalcharlie]

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

[@randysummerhays4168]

Nothing short of genius

[@crash4142]

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 🤙🤙🤙🤙

[@jacobkrueger9211]

Thank you, this is awesome.

[@nuttersspeedshop]

Glad you like it!

[@charliebailey2359]

This is by far your best video yet!

[@Mogachaffe]

Quite the amazing build

[@grantensrud9185]

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.

[@stuka151]

Great video Nutter. I shared this with some guys at work today. One of them ended up sharing pics of when Boss Cat II stopped at his father in-law's house in New Richmond.

[@nuttersspeedshop]

That is awesome!

[@MidnightPolaris800]

Way cool, I wonder if it will ever get driven on snow? Would love to see that video

[@nuttersspeedshop]

Yes, it will if the weather cooperates. Tommy and I plan to be there for the test run if at all possible.

[@506curtis]

Man what a cool guy and an awesome sled.

[@nuttersspeedshop]

I agree.

[@killianknutson3751]

If you're doing a second video and that bike behind the sled is a KZ1300 you should definitely cover it. They are super cool bikes that not enough people know about.

[@nuttersspeedshop]

I used to own a KZ1300.

[@dubiousf00d]

Absolutely breathtaking machine!! With actual kawi snopro parts. WOW! Absolutely Impressive. Would love to see this in person

[@nuttersspeedshop]

It is my understanding that Brad will want to show this. I'd look for it at St Germain Wi and possibly the Chicago area.

[@dubiousf00d]

@@nuttersspeedshop I will do that! Thanks

[@jodypierson3137]

That man is my new Hero

[@Zzeke]

Awesome work mr Paul! Thank you

[@darrylsmart1783]

That's Awesome!! What a great guy! Smart fellow!! Thanks Nutter!!

[@darrylsmart1783]

Oh the first time I saw a Kawasaki was in the movie. The Omen !! 666 lol

[@nuttersspeedshop]

You bet!

[@chopshopchopper]

That is one tight job, awsome job for sure...

[@stevecleveland357]

Unbelievable talent. Very cool indeed. Thanks for sharing

[@nuttersspeedshop]

Thank you! Cheers!

It's great!

[@donutdan1508]

Excellent Burt Munro comparison. What an great interview! ✌️🍩

[@nuttersspeedshop]

Thanks!

[@IndyGuyRob]

Thanks so much for doing that video Nutter! Wow! What can I say, simply incredible! Sooooo much engineering put into that😳 And all done with no computer drawings/layout, simply amazing! Very few people with that kind of mind and talent! Can only imagine the wealth of information that could be learned from him Don’t forget 77 Kawi Sno Pro cylinders too! Wowzers!!! Cheers guys 🍻

[@nuttersspeedshop]

Paul is incredible!

[@Mystic-l3r]

Oh damn. That's a clean build with style.

[@yelyab1]

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.

[@AnDrEw122100]

That thing is wild . If I was rich I’d fund this man to build whatever his imagination desired lol.

[@larrywarner9314]

John that's awesome I'm glad you shared that , I live in Williamsport Pa and I live couple blocks away from Textron they build airplane engines there ,that's probably the coolest snowmobile I've ever seen thank you for sharing

[@nuttersspeedshop]

Thanks Larry!

[@seandurfey2360]

The coolest motor i've seen!! unreal tech..!

[@nuttersspeedshop]

We agree!

[@steelwheels327]

Paul is amazing!!

[@allanweseman5433]

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.

[@IowaBudgetRCBashers]

What an amazing feat of engineering

[@krawdaddy33]

Im glad he got pictures of the crank, that's an awesome design!!! He says 200hp.... im curious what the torque figures are 😮 probably around 400lbft+ with five frickn cylinders

[@ChiefRickyRC]

Cool sled and build 👏

[@davefuelling7955]

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]

That makes sense. Thanks.

[@Sean-i4r]

Wicked cool builds congratulations

[@jnljnl8485]

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

[@jackwillson8099]

Very smart man too come up with this set up

[@henryandejbelcher7902]

That is a cool engine sounds great.

[@James-qr6rp]

That thing is a weapon that would make a sick drag sled I would love to see this thing in action ..

[@nuttersspeedshop]

The plan is for it to get ridden at some shows. I am not sure if track time is in it's future or not.

[@ELITEWELDER1]

ELITE BUILD!!

[@DeereHunter]

Wow! Great video Nutter!

[@nuttersspeedshop]

Thanks!

[@notagain8661]

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

[@dankuspanku4650]

That is one of the coolest goddamn things I have ever seen.

[@Z-Ack]

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..

[@jlo13800]

I dig them 3 phase 2 strokes!

[@andrewgasch9504]

How cool is that! 😍

[@GarageWorx]

Amazing machine. A true craftsman.

[@nuttersspeedshop]

Couldn't agree more!

[@HeadlineNews]

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

[@tca375]

Love guys like that amaze me!Great content!

[@nuttersspeedshop]

Paul is a genius! He's got even more ideas fur future builds.

[@GoofieNewfie69]

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

[@Sawmillingwithj1973]

another great video thank you for sharing be safe have a great day and God Bless

[@nuttersspeedshop]

Thanks!

[@methanial73]

Really cool!

[@glennspreeman1634]

He looks like a normal human being, obviously super human!!!

[@nuttersspeedshop]

I would agree.

[@tonykraft85]

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…

[@larrywarner9314]

I love those 108 pro 4 clutches

[@itsjustmeinidaho]

Very nice

[@jacktheripper-hp9tx]

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

[@RadDadisRad]

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.

[@waynegarfield6607]

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

[@nuttersspeedshop]

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.

[@Idrinklight44]

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

[@gregsidel3557]

Sorry I hit the wrong button i'm new on this channel and i'm just Wondering how come The oil mixture was so rich on Paul's engine

[@alanrouse7285]

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

[@theoldman8877]

Engines that rotate the cylinders and crankcase around the crank shaft are roterary engine. Rotary engines were used in World War 1 fighter planes, propelled bolted to the outside of the crak case, motorcycle, rim for tire bolted to the cylinder heads the crankshaft forums the axle, and one prototype automobile the car had a ring gear bolted to the cylinder heads and opinion gear connected via axle to each of the rear wheels . The car looked promising until it snowed at which time opening or closing the throttle would cause the entire car to spin around the engine I forgot to mention the engine was mounted so that the cylinders formed a flat plain Circle parallel to the ground . In radial engines the cylinders do not rotate around the crankshaft . The sales department at Mazda called a Wankel engine by the wrong name and that has become common practice today . It is another one of those cases of wrong 100,000 times is still wrong, common practice but still wrong .

[@allanweseman5433]

OK Paul, now you need to find a 2010 Honda VFR 1200f motorcycle, which is a V4 1,237cc 4-stroke and mount your blower and four of your 2-stroke watercooled cylinders on it and make a 2-stroke superbike. With your skills it would be a lot easier than what you have just made.

[@bryansellner5811]

Morning Nutter !!!!

[@nuttersspeedshop]

Hi. It's evening now. LOL.

[@jlo13800]

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

[@bigboresledder]

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

[@nuttersspeedshop]

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

[@joehanson2635]

This guy is amazing he is like a mad scientist foe Engines you might want to wear underwear linners That thing will scare the shit out of ya.

[@patrickrobinson59]

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

[@ricksorensen9480]

Amazing engineering, I do similar projects using steam engine parts that I make from scratch and attach them to small IC engines crank case for a lubricated cross head and crankshaft assembly,,crazy stuff I do, a different way of thinking to produce a one of a kind working engine, very intertaining projects that make people think & laugh,,my highest admiration of your intelligence.

[@FUELFIREGARAGE]

Great video 👍👍👍👍👍👍

[@nuttersspeedshop]

Glad you enjoyed it!

[@grandenauto3214]

Nothing like the smell of Castrol R

[@Jake-ph6fl]

Oh Nelly.. One word INSANE this is not a sled it a rocket launcher my goodness.

[@victorriceroni8455]

Very cool.

[@willtay3016]

God damn genius

[@nerd1000ify]

Cunning design, I was wondering how it could work with no crankcase compression until you showed the blower.

[@darianballard2074]

Very cool 😁

[@thomasarmstrong1271]

Can the clutch handle it

[@weednerd_dwc]

love this, nice work \m/ \m/

[@joedoakes8307]

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

[@Paulman50]

This guy is more like John Britten, an absolute amazing guy, also like Bert Monroe he is a Kiwi.
