Outstanding! Nice explanation and great shots of the setup. Thank you so much, can’t wait to see it rip!
Turn your cylinders around, I did in on my 500cc polaris go-cart and it works perfect. Exhaust is in the rear and away from the motor.
Love 2 stroke Polaris engines. Good work on the build and the explanations on the work is outstanding.
A 90s polaris atv transmission like a trail boss or scrambler works amazing.. hi low and reverse
If you want reverse check out Polaris atv transmissions. That would give you high low and reverse. I've seen motorcycle engine buggies running them. Your cvt secondary might even bolt right on.
I have a Polaris snowmobile engine in my project off road buggy.. I ran a Polaris 350 Trailboss transmission, it gave me a low, high, neutral and reverse..
Dude I been wanting to get one of those transmissions for so long to put it on a hinda fl250 oddesy, it would make that thing so much more usable. A real transmission aswell as electric start and you can go anywhere. Where did you get yours?
@@westman8527 I bought it online, paid about $250 for it, just hooked up the speedo, and the neutral/reverse lights. I saw a basket case 350 Trail Boss for sale local for $350 or so a couple weeks ago, I almost bought it just for a spare transmission. I have some Fox air shocks coming today, should take it to the next level..

Been waiting to see how it was completed, being in Australia, motorbike engines are far more common.
Plus sleds are super fast... And most are two strokes... Definitely a great way to go... Nice set up.
What’s the overall rear width with the Miata axles? I love how you took Kyles already budget friendly build and made it more budget friendly!!
As it sits with these wheels 63"
@@jdsgarage701 Oh awesome! For some reason I thought it would be wider.
Thanks so much for doing this video, excellent info for those of us that are thinking about building one!
I also like your upper shock extensions.i used to have a rodded 93 thunder cat dynoed at 191 hp,man do I wish I had that motor now!
The real reason why those are there is because of the suspension style we used. With a 3 link suspension the shock has to move in 2 planes rather than 1 like it would with A arms. So they were used to attach heim joints to the ends. Some shocks will have them build in but these didn't.
Rather than running the engine in reverse flip the jugs around on the case and run it correctly just with the exhaust in the rear and carbs in the front.
It won't work very well trying to run it in reverse all the time. Power and speed is limited in reverse to keep people from getting out of control and crashing or hurting themselves.
We have also considered this as well. But on some engines this can't be done as the jugs physicaly can't be reversed because they won't fit backwards. If we were to run the engine in reverse we would flip the forward and reverse ignition timing around. Still trying to figure out the best solution on this.
That's a challenge for sure. By the way, Polaris went to a electronic engine reverse as well, late 90's. The secondary isn't symmetrical for forward/reverse either. Or the chain case tensioner. Can't recall if the brake is designed bidirectional. Maybe those aren't changed?
A arctic cat fire cat engine would put the intake and exhaust on the same side as well as not have the reverse low rpm timing. If it is a diamond drive model you could still have a reverse gear as well.
Thanks so much for the video. Great insights
Hey! Awesome video for sure!! I've always wanted something like this with a snowmobile engine in it!! Would you make the chassis for customers? I would think that would be the toughest part and if you've made a few already it would really save a guy some time. It looks like you do a great job!!
Great job I'm in the process actually for the last past year stuck in that this should help out alot👍👍
Glad it helped
damn that's a nice build
Thats awesome. No snow mobile in los angeles. We have lots of totaled harleys and suzukis lol
Polaris has PERK same as RER started in 02 reverse chaincase kits run 250-300 used they're quite desirable.
I like it very simple and clean
Great video. Awesome explanation
Hi JD's Garage nice build and good info nice looking buggy all your info is helpful also can you show and tell how you did your shocks on this buggy how you made the top mount on the top of the shock thanks.
Working on the video will be out soon.
Any videos on your frame building?
I run skidoo snowmobiles. The RER reverse is awesome but limited rpm. Like a quad/four wheeler that needs a reverse over ride button the snowmobiles are limited in reverse as well.
You could build A Rotax on a Buggy frame ??
@@5dsunny713 for sure! Ideally with the entire "drive train" minus the drive cogs for the track. It'd make figuring out the gearing much easier and snowmobile belts are some of the best available
There is a guy who makes the engine mount kit but he’s so busy !!
@@5dsunny713 I have a dream build of using an 800 etec skidoo power train in a golf cart chassis. Something about 162hp in a heavily modified golf cart go cart just tickles me... A mix of "Brappppp" with tires howling.... Those are angel songs my friend.
@@tenflat2009 I would pay to have one done .. I’m in a wheelchair now I can’t do it at all
ive got an old evenrude it has reverse just the drive box is all ive got left
Says he's from MN with North Dakota plates.
So are you premixing the oil and gas or is it oil injected? Did you do any modifications to the engine as far as sparkplug gap and primary clutching?
Mantap bang...😁🙏👍
I’m getting ready to do a build with a 440 motor. Is that a rzr clutch your running on it?
Beleza 👍👍😎
I like your idea of mounting snowmobile engine backwards. The manufacturers limit reverse speed with ignition timing I think. Do you have any ideas around that?
Great video lots of good info
Congrats on knowing that 2 strokes need back pressure to run right a lot of people don’t know that
Wjats that
2 stoke engines need positive pressure in the exhaust pipe. Since they do not have valves the piston and exhaust pressure act like valves.
@@jdsgarage701 i know but like no one is running a 2 stroke without the pipe
thanks for the great explanation
Looks like the Polaris 340 engine they run forever I still have a couple of them
1991 Polaris 440
She don't get to hot mid summer being air cooled?
you have built a great machine but was going to comment on your engine choice you said you were looking for i think your limiting your self to few choices and running it in reverse seems slightly exstream and all my sleds with engine reverse have rev limiters not saying you couldn't possibly bypass but the engine your running now cant you 180 the cylinder's my polaris 600 and 650 triples i have spon the cylinders for clearancing issues in engine swap projects
Thanks
Polaris has P.E.R.C. Engine fires in reverse... for reference
Im trying to figure out how you mounted rear brakes.. I have rear polaris carriers and Miata hubs and cv axles.
Would you be interested in build one if I had all the parts included wires and complete rolling chassis
If I built one with a polaris 500 with perc reverse, do I put the motor in the front like the snowmobile or in the back like you did?
Also, is there any chances in the jetting for summer use compared to the winter?
Good job My friend👍
@JD's Garage
Hey I have a 900triple 2stoke Suzuki snomobile engine. If I was willing to pay to build a crosskart out of it what am I looking at price wise vs. Diy. And what if I want the kart 3x faster the snowmobile was clocked at 125 on an snowed plane runway
Thanks for this video! I'm going to try to put a 120 hp Viking Pro engine in a 70's dune buggy. Did your center section on the drive axle come with the buggy or was it fabricated? That will probably be my biggest obstacle.
Check out the very first video on the channel it goes into detail about how this one done.
I got an older polaris 440 engine from a guy for free and have been debating what to do with it, it seem you know much more about these things than me lol, would something that small be powerful enough for a crosskart or should I put it in something else? Maybe swap it into a Honda Odyssey?
That's exactly what's in this kart. The engine came out of a 1991 polaris 440 sport.
That would really haul with 98 XC 700 twin.
Is there anyone doing these builds for ppl . Im disabled I ant one I can’t ride quads
So how does the air cooled motor do in hot summer weather?
Works perfectly fine. You have to remember the engine was in an enclosed area with the exhaust pipe and limited air flow. Now it's out in the open and has increased air flow. It's also jetted a little rich to help with it. It's been ran in 95° heat for 2 hours and never had an issue.
What the total cost of this build. (Around about) $
Including the recovered money from scraping unneeded parts from the sled the build cost around $2400.
That thing is mint
stagger ? you mean offset anyways nice build
Awesome video! I purchased a spool kits and am thinking about going with the trail arm set up like you have here. What shocks do you recommend and what lengths
Thanks in advance
Merry Christmas !
Pretty much any atv or snowmobile shock would do around 120/in is what we use. Length depends of what you can fit with enough clearance.
@@jdsgarage701 Thanks I ended up ordering a pair of Fox Podium X, I think that is what you are running also.
Badass my dad built a similar buggy
I noticed you don't use use a rear sway bar, why not ? also do you have the 3D printed plasma table parts available ?
Yes the 3d printed parts for the plasma table are available on our website. Regarding the sway bar, it's added complexity that didn't need to be there. Sway bars for the most part are unnecessary especially for offroad builds where body roll is less of an issue. It's much more important to have your wheels be able to move more than 3" independent of each other. Rather than try to eliminate body roll that probably doesn't exist.
hello, nice project looks fast where the plans are obtained
The cage plans came from KJ Raying. The rest of the kart we designed.
If you wanted to run that engine in reverse i would cut a new keyway 180° from the old one at tdc
What rear shocks are you using, I would like to make the same suspension as you are, Thanks Al
Ryde fx shocks from a polaris outlaw
where did you get the 14 tooth sprocket, thanks al
Pretty much anywhere online. It's a 50 pitch 1" bore and 1/4" keyway.
@@jdsgarage701 THANKS
Audio is inconsistent
I absolutely hated this your front tires are on the wrong way my ocd made me bang my head in my un deserving phone which lead to pre mature phone sim card rejection
That one wheel has been like since we build it but it's been so much fun driving it and it's not noticeable so it hasn't got flipped around yet.
How many Hp does it have ?
52hp
@@jdsgarage701 wow,. those thing are Powerful,, I thought the CC'S Multiplied x 17 Equals Horse Power. ??
@@jackedwards2129 It's a 2 stroke engine though so it's displacement could be considered double when comparing it to 4 stroke engines.
@@jdsgarage701 wow.. ok,,,
Ever heard of expansion chamber exhaust ? You can make custom exhaust for any two stroke engine in the world, its done in snowmobile racing all the time. Get real.
Lol. U didn’t catch hell for putting a sled motor on a cart. 😂. I had assholes say oh u can’t run that in summer. Yes. But the sled the seat has the rad underneath. But u have blower style and rad style but if u run fans and a big enough rad. Or u drag it.
The engine running backwards, does not run as good as running it in the way it was supposed to!!
I think you over engineered everything!
idk how all of you make these videos without even showing it run lol wack
