We're building on offroad shifter kart buggy! The base frame for this new project is a Manco Deuce go kart with a semi-independent rear suspension. For the power plant of this build we will be using a 2001 Kawasaki Ninja 250r Motor, which should have more than enough power and the 6 gears should help us have tons of torque and a decent top speed for this crawler! We used spring assisted shocks in order to allow for a much longer radius of travel within our rear suspension section, we also added a lengthened pan hard bar to allow for less change in our rear alignment as the suspension articulates.
Thank you guys for watching and be sure to subscribe to see us finish this thing and rip it!

Sup guys new project delivery, so this bill is going to be awesome. We've been wanting to do something off road shifter for a really long time. Now this is a man come deuce go-kart. It has a semi, independent, rear suspension and the kind of J arm front suspension a lot like the Odyssey we worked with and we're going to make a crawler that can also hopefully go close to like 60 70 miles an hour.

The way we're gon na do that is we're gon na sell a Kawasaki Ninja 250 motor into it. I hope you guys liked the video where we got this thing running, but we're definitely not keeping this bike, as is because it's Oh real, hoopty right now. So what are we doing in this video days? Yeah? So in this video we're going to be doing a lot of rear suspension, stuff we're hoping to get around like maybe 10 inches of flex? Lift it a little bit put much softer Springs that moves a lot more it'll be a lot of fun. Let's get started skidding unit boys alright, so this is a Manko deuce.

We bought for two hundred dollars uh and we pretty much know exactly how we're gon na go with the suspension on this thing. Redbeard actually helped us out a lot. You should definitely check out his yellow deuce, build that thing. It's awesome.

That's kind of inspirational buy one, do one of these because you really like this rear suspension. So the idea is: there's only one heim joint at the very center of this whole back section here and what it can do is it can move in any direction, because it's only one joint, this panhard bar keeps it from moving, basically from twisting in a direction. You wouldn't want it to move, so it still flex left and right kind of like a solid axle. Unlike a jeep or something these are actually automotive.

Spring-Assisted shocks bought these from Summit Racing. We've actually never used these before, but it really seems like a better alternative to go-kart shocks, because a lot of go-kart shocks don't really give you as much travel as we'd want out of this thing, because the name of the game of this thing is going to Be a crawler, so what we're gon na do first is: it looks like we might actually be able to bolt these up and get the stock shocks out of here. I'm able to see how strong these strings are. If we're gon na be able to support the weight or not it's about suspension setup, it's more flexing than our other offer carts we've had, but it's still, we don't really get that much flex.

If you can see the shot goes into the social sleeve, but we still only have like six inches travel right there. So when we put these things on, it should flex a lot easier, be a lot smoother and one tons more room to move. So, as a baseline, we're going to do a stock suspension travel test. How are we looking the back wheel, all right, so that sucks, I'm sure I didn't actually just measure it, but not usually gon na measure, the jack height? It's that's about 10 inches.

That's also! A healthy estimate, it's probably less than that, but we'll call it 10 bar. That's like change. It changes your toe in and out when you're, driving and stuff. You would take the springs out of this gyro, the complexity.
Let's get that side-by-side, yeah might be slight difference. Yep I'll squishier these bad boys - oh really it's up like there's, not that big difference yeah just this is like these aren't super hard, though. If we do have issues with how much these compress, we could also move them in two. So the radius of travel is a little bit longer and it'll be more force on the spring.

I think we should go for that monster truck. Look honestly right. There goes the other shot yeah. So what we're gon na do now is we just want to try to figure out how much the stock on joint is limited.

So basically, let's just see holy cow. I look funny yeah yeah, so basically there's there's no limitation in the hi choice. If we want stupid amount of flex, we can get it see. Does she fit? Oh? No.

We need even more yeah, okay, so we're thinking this is a little too high unless it goes down a lot, we're probably going to end up moving it closer in and at welding in a hoop. So it looks a little more prerunner II too, but let's see yeah, let me jump on it. I want to see you fit. Oh that's, better flex, oh great yeah! Oh man look at much.

We still have a front tire. Just came off the ground, so yeah. So fact limits no flicks at all sweet. The pilot is about see you can see how twisted it is like so there's no pain heart of our obviously so we're going to lose some flex but like for a go-kart, that's pretty crazy.

I also feel like we're limited by how much it can travel out is our ride? Height, isn't really secure, yet yeah yeah hold the bottom shocks on. What we realized is that we only got like two inches of downward flex when you sit on it, we're going closer to four or five, so we did was remove the pivot point on the shock closer to the radius or axis of rotation. So basically we got these done now. We can rebuilt up the subframe and start working on the top hoops for our shocks.

Visitors because he's just having a blast at a fan here. Look at the livery on that thing. You read yeah well right now, we're doing is we're actually ditching the idea of the hoops, because what has to happen is our shocks are gon na mount basically right about here. So, instead of just like being super redundant and like cutting this out and making a hoop just for like looks we're just gon na.

I made up this little bracket here and I'm gon na weld it to the bottom of this drill, a hole and our bushing and self a fit perfectly. It's not a way so we'll be able to use the hoops on the front suspension, but for this video and the rear suspension we're just going to stick to these, so our brackets are just tacked in for now, just so with any kind of suspension components, you Kind of want to just tack everything first and make sure it doesn't bind there like you, have enough travel or saw too we're worried that, because we angle the springs and we moved our pivot point closer, I think it's going to be a lot spring or hopefully Not too much, let's find out, unfortunately, well it's kind of good because we found the other extreme, but this is just a little too springy I mean it looks sick and we're I'm sure to a lot of tons of flex like even sitting in it kind of Just takes it down a little bit, it's just on because we need to like have it on the stiffer side just for ride quality, because there's no doubt we'll be able to flex it out and stuff. Okay. So now it's time to work on our bar traveling hour, we're going to call it essentially what it does is, so we don't have like a bunch of wiggle left and right.
It's just a bar that you weld in with hydrants on the end, and it goes up and down with your suspension. The only problem with this kind of setup is that when it does go up and down your suspensions, ever-so-slightly gon na turn to the driver side. If you make it like this, I do now is we have our top mount done, we'll drill a hole in that, and then we need to figure out how we want to make a connection up to our bottom. Mount actually part of the cut off original CJ.

Bumper that someone just made of construction angle iron super super thick stuff, though it's gon na be good for our panhard bar. I don't know if that work did we intended yeah it came off. Our bar is in all our suspension, is pretty much all tighten up and ready to go well, the tires are really even we haven't gotten to go power sports one yet so, but as you can see, I got a lot of play in this. It's really cool.

It's also the shocks are really heavy so, like I, don't think it's gon na bounce around too much like there's a lot of absorption. I think it's gon na take a while for it to come back to normal all right, so we're maxed out on flex or nearly we could have more about the panhard boards actually touching old mount, so that could probably give us degrees wise. I could definitely give us a couple more inches. That's a point of flex in the back third go-kart guys like if you scale this up to be like a CJ that'd be insane and the front wheels lifted.

But when someone's in the seat, yeah yeah I'll show y'all right now like holidays, just a little bit of weight, yeah and she's stuffing. So, even though we got 12 inches of flex out of the back so far, the front is still has no give with the shocks it has on it right now. So once we do the suspension, the front should get a little bit more if they're doing a flex test on the other side. Since the panel up bar on the set is more downward travel, it's pretty crazy to be max up the jack yeah, and this tires flat.

I'm telling you - and this is basically like if your front suspension is a block of wood - is what we're dealing with here. So this is crazy. I mean I'm just excited for when we're like at the trails we take the Jeep song and we can, like I mean having like a rock here and still having their front wheels on the ground. The plan is, though, we're gon na make hoops for the front and then have the same exact shocks for the front.
So this thing is going to be decked out we're gon na some big old tires for go power. Sports stay tuned for this, build for sure, but anyways guys. I think we're gon na wrap up the video here. Thank you so much for watching.

Thank you. Go power sports they're, gon na totally soup up this build so stay tuned. For this thing in the ninja 250 shifter engine and bit new tires new, we actually plan to do aluminum panels here light bar aluminum roof, maybe even doors to me, a huge build, see you next time.

    Dragonfly by Shamans Harvest. You are welcome

  4. Avataaar/Circle Created with python_avatars Alasdair says:

    Just be sure to put sleeved mounts on the bottom of your shocks, otherwise the mounting eyes will break off when they get repeatedly twisted sideways.
    Looks good so far, cheers.

    Its called Suspension TRAVEL, or spring Compression, NOT FLEX… LOL . cringy.. great job tho guys

  6. Avataaar/Circle Created with python_avatars Kegan Burris says:

    Maybe a cv axle long travel suspension for an off-road build?

    Great video! We appreciate your business. We cant wait to see how it runs!

  14. Avataaar/Circle Created with python_avatars dbjf3 says:

    Move your top panhard mount either in ward or outward a little so it does not hit the frame under flex

  15. Avataaar/Circle Created with python_avatars frederic rike says:

    Can you get some slightly different springs for the rear shocks? Say 10-15% less rate? That should give you a little less stiffness and will 'travel up and down easier. For speed alone you want stiffness- for crawling a softer more compliant suspension is what you want. I have popcorn- if this takes a few episodes, I'm ready!FR

  16. Avataaar/Circle Created with python_avatars Joe says:

    it would probably be too difficult to make this 4×4 wouldnt it..
