From an engineering/fabrication standpoint it's great. That being said, hearing the roar of a 45 degree v twin out of a vintage sled is somehow sacreligious.
That's awesome. Great idea. I see a movie trilogy coming. "Hells Angels on Ice: The forgotten years". "Hells Angels on Ice: Fighting Mounties and Frostbite" "Hells Angels on Ice: Sonny Bager, The Toeless Leader"
Damn that’s so sweet. I was like man that thing is going like 85mph all day. 88mph!! With that set up is pretty sweet. No chain drive all clutch. That’s impressive.
ironcast no way in hell a 45 degree (tractor/harley) motor sounds better than a small bore 70's 2 stroke twin. Search rotax type 354 and open the guy doing asphalt runs. Now that is the sweetest sounding snowmobile motor of all time (even if it's transplanted into a junk polaris tx chassis).
Bob Rynda, you did some really nice work here. I have a '73 Harley Davidson sled that I would like to do the same thing to. I realize that it is a mid-mount engine chassis but I already have the solution to that drawn up. I know you previously stated that do to liability reasons you would prefer to keep your drive engineering private but I think you should patent it! I would be willing to pay for and sign a waiver to have you make up another or furnish some drawings and a parts list. Hope this makes it to you.
Did a nice job on it. I like it. With all the work you put into it I would rather you used a original Harley-Davidson sled. Even with the mid engine mount you could put a front mount bulkhead with IFS. But that's just my opinion. Still a very nice piece of craftsmanship. Two thumbs up!
HA!! Too Cool!! Frikken Love this!! I've thought about doing the same with a Sporty engine, simply because they so readily available, and so damn reliable. (and cheap too!)
Hans Schtuk citation ? You've gotta be talking about a citation ss. (Ss being the 368 with twin carbs). The plain ol 4500's were only good for 65 or so.
If you bolted on an 80” evo with the same carb, se57 cam adjustable pushrods and valve springs and cycle shack slip-ons 1/2 the price and twice the torque, 20 more horsepower, w/stock compression, up to 40 with 10.5:1 JE pistons (factory recesses for high lift cam valve clearance) may have to use a milling machine and end mill to trim the case to clear the cam lobes. Or make a FATVO BLOCKHEAD 88” TC heads on an 80” evo lower, i think it adds up to 99/100” ? Don’t recall. Looks sweet, Id like to see it at its potential though!
You must have figured out the Gearing .. Because HD's don't rev very high .. My 4 Stroke Yamaha turns 10,250 RPM .. it has a 20% reduction gear to the clutch .. At 998 CC's it makes about 160 HP and runs 116 MPH on GPS..
In Harley's defense, the old HDs had a chain oiler that dripped a small amount of engine oil to lube the chain. That's where that leaking thing came from. Most of the newer ones aren't really that bad for leaking oil.
Harley Davidson actually marketed a snowmoblile. I cant remember the year but it was a pretty thing with chrome skis. Wasn't one bit of good and leaked oil like a sieve. Didnt last long.
When you want a Harley but live in Canada lol
Speaking as someone who was around when Harley made sleds. This thing runs faster than any Harley sled did.
I seen that sled at the scorpion homecoming in Crosby Minnesota!! Nice that you made a video. Sure wish Scorpion would have stuck around😎
One of the most badass things I've ever seen!
Said the squirrel to the chipmunk!!! yeehaw!
Awesome. And 88 mph is plenty fast enough. The guy is a visionary.
OUTTATIME
That's what all snowmobiles should sound like. Perfect job!
From an engineering/fabrication standpoint it's great. That being said, hearing the roar of a 45 degree v twin out of a vintage sled is somehow sacreligious.
I'd take that over any if these new sleds. Man that's a wicked build! Respect✊
Slow as fuck
@@mikeslocum4966 Is that what your 5 th grade teacher wrote as her assessment of you ?
What a beautiful sounding machine what a cool idea
I think this thing actually takes the cake for the coolest thing I think I've ever seen
Best of both worlds!!!!
Very clean and nice machining!!!
Tommy Boy ..
Well that is just plain freakin' COOL!!! Good job!!!
That's awesome. Great idea.
I see a movie trilogy coming.
"Hells Angels on Ice: The forgotten years".
"Hells Angels on Ice: Fighting Mounties and Frostbite"
"Hells Angels on Ice: Sonny Bager, The Toeless Leader"
Harley engines in general do nothing for me but this build and the remarkable fab work is awesome. 5 stars!
Nicely done. I thought about doing this back in the early 80’s when I owned a 74 inch shovelhead.
Damn that’s so sweet. I was like man that thing is going like 85mph all day. 88mph!! With that set up is pretty sweet. No chain drive all clutch. That’s impressive.
Nice job, very clean and well put together.
Wow! I am a fan of Scorpion snowmobiles and a lover of Harley's I have owned both!! And would love to own this awesome machine!! Great job!!!
Beautiful machine !
Nice Fabrication work (Messerschmitt perfect)
sounds awesome! 👍 looks great too. the old scorpions rocked like a hurricane.
I bet the Torque is the fun factor for this sled,a real nice professional job!!
First good sounding sled I have heard
Back in the 70’s Harley Davidson had a line of a few snowmobile’s but they didn’t last long only a few years.
Check the Harley snow bikes of today..sick
Ya they werent all that good either. They looked good though.
That was AWSOME. It would be cool if H.D would start making there own snowmobiles.
Craig 2E They did make them back in the early 70s.
Nicest sounding snowmobile I have ever heard.
ironcast no way in hell a 45 degree (tractor/harley) motor sounds better than a small bore 70's 2 stroke twin. Search rotax type 354 and open the guy doing asphalt runs. Now that is the sweetest sounding snowmobile motor of all time (even if it's transplanted into a junk polaris tx chassis).
They both sound good.
My turn to take it for a spin..... Awesome setup.
It sounds like an old WW2 fighter going by lol
what a quality Mod! Nice work!!
Still have a lot of throttle left .. lol. Could pull a mobile home with the damn thing !! Love it !!
Wicked fast!! Faster then what I would have guessed
88 mph all you need is a flux capacitor....
Amazing job grafting that motor in it!!

I love when a guy goes "i didnt want that so i BUILT my own transmission"
Maybe the best sounding sled i've ever heard. Very nice
OMG.....I just love the gas tank !!! thumbs up !!!
That's impressive! Let's see; Speed, awesome sound, nice craftsmanship with attention to detail...and, I have not seen anything like it...
Sweet looking sled, outstanding engineering.
Freedom sled! Murica! xD
Best sounding 4 stroke sled!
I've always wanted to see a Sea Do, or any jet ski powered by a Harley engine.
Literally working on that on a js550 stand up ski right now lol
Looks great, sounds great.
Excellent 🎉
That is bad ass in so many levels
sounds like a Harley goin by, great sound
That's badass!
Cool! With snow underneath you can really see how much oil it’s leaking!
Boat Axe twin cans don't leak. it's not a pan shovel.
Jason Hausmann I know, but it’s still funny.
Hahahaha!
I gotta say that is pretty cool
Almost looked like a rainer beer commercial when driving ur sled fast in the video lol
ThatS very cool , good work
HA!! Too Cool!!
Frikken Love this!!
I've thought about doing the same with a Sporty engine, simply because they so readily available, and so damn reliable. (and cheap too!)
Now that's a super twin eh
Righteous!
very nice job!
Get some!!
My 83 Citation would hit 80mph. Nice job on your sled.
Hans Schtuk citation ? You've gotta be talking about a citation ss. (Ss being the 368 with twin carbs). The plain ol 4500's were only good for 65 or so.
Maybe in the back of a pick up🤔
awesome bud love it
Sweet!!! Love that HD V Twin!
Nice...
But I would want the manual trans!
Scorpion snowmobiles were quite nice back in the day.
Sweet I’m surprised you didn’t travel back in time and put this in Harley’s lineup for next year
Guess who's going back to the future.
Need to paint it Harley orange with black stripes.
Coolest sled ever
Unreal!
MMMMM Daddy likes!!!!!
FUN man!!🤙🏼
this would be some thing Tim Allen would do LMAO LOL ....... u better show this to tim allen have him ride it lol
Bob you are a evil genius..LOL!!!
Very very cool
Twist and go?
Huh.. I've seen plenty of 90 mph fly by's....I was going to say about 70-75. Cool sled any way.
this is groundbreaking! not the build, but a harley rider wearing a helmet
I think its great.and sounds nice
Wow That's Cool
I’ve never seen anything like it before ,👍
That thing sounds absolutely amazing with a capital F
Very cool
Nice 👍
If you bolted on an 80” evo with the same carb, se57 cam adjustable pushrods and valve springs and cycle shack slip-ons 1/2 the price and twice the torque, 20 more horsepower, w/stock compression, up to 40 with 10.5:1 JE pistons (factory recesses for high lift cam valve clearance) may have to use a milling machine and end mill to trim the case to clear the cam lobes.

It's a killer.yea baby.T800Aust
Yes but how much oil does it leak?
In Harley's defense, the old HDs had a chain oiler that dripped a small amount of engine oil to lube the chain. That's where that leaking thing came from. Most of the newer ones aren't really that bad for leaking oil.
@@429thunderjet2 I get that l, I'm a Harley owner my comment was just part of a long standing joke
Nice
looks fun to cruz
Cool
Badass!!
THAT THING RIPS
Harley Davidson actually marketed a snowmoblile. I cant remember the year but it was a pretty thing with chrome skis. Wasn't one bit of good and leaked oil like a sieve. Didnt last long.
They made it for a few years and mine never leaked. The big issue with mine was the metal skis and the weight. A trail machine only.
Dude!
hahaha thats awesome i just put a honda atv motor in a vintage snojet on my channel
that's it... I LOVE YOU !
Thats so cool! Is that an old indy?
It's a Scorpion.
It’s a Scorpion TK ( Trail King).
Awesome!
Wonder if a predator 670 would fit
It would probably go faster...
I LIKE IT!
Always thought Harley’s were sleds😏
awesome
Love it.
