Taking the dual engine go kart off road

[@walkermediaworx]

Great suspension work! People who are saying it looks slow - going too much faster in a Kart that size would just end up bending something with some of the rough terrain he's hitting. I think it's doing a pretty good job as an off-road kart. Wouldn't win any drag races, but that's not what it's built for.

[@thegenerousdegenerate9395]

Agreed. It's got all the power it needs. He's not really getting into in this vid either, which just proves he doesn't NEED more power. Don't get me wrong though, the more the merrier. There's never enough HP. LOL

[@Goathierbmw]

Yes true, I think it is working great for what it eas designed for, plus the engine camera really show the suspension! I am building a CBR600 buggy on my channel Really not underpower tho ahah!

[@zuestoots5176]

My Robin did 45mph with 6.5ho.. this thing is stupid slow and unstable from geometry issues/

[@peterratcliffe5115]

For anyone interested in extra speed and performance, take a look Rage Motorsports stuff. It's a small company here in the UK. They make off road and on road buggies putting out over 200hp in some versions. Same size buggy as this one.

[@Rockin_Roll]

I was just thinking the same thing....I would never want the engine attached to the independent suspension....my guess is you'd be asking for (engine) trouble...but, it's his (money/channel)......I get it...

[@jstephenallington8431]

As long as the engine is mounted fairly close to the pivot point, (of the suspension arm) movement should be a non-issue. The further away from the pivot point it sets, the bigger the issue. Still, mounting them to the frame might have a little less movement.

I love that thing! If you fix the suspension problems I would ask about $5500.00. Wish I could afford it! Suggestions: One more shock on each side of the front suspension! One more shock on each side of the rear suspension. Can you add shocks with out adding springs? Small front skid plate (Better to bounce off than dig in). Sway bar not sure where (real curious what affect it would have). Those motors really shake. That can't be good for them! You have become one of my favorite motor sports channels on the Tube!

You gotta start putting bigger motors in this stuff man lol love your videos but your always worried something is “under powdered” well start throwing bigger motors in.

[@thegenerousdegenerate9395]

It's not as much the about motor size, as it is the frame size... Lol When he sets out on these projects everything makes sense but then somewhere through the middle of the project he looses the plot and starts building a monster truck. Lol He should probably just pick up car motors from the wreckers to begin with... Lol

[@casey8207]

I wasn't crapping on him by any means his talent is through the roof. the fab work and creativity behind these things is impressive I wouldn't even know where to start. but your exactly right about the frames and chassis hes building. hes putting motors in these things that people are putting in shifter carts that weigh 10x less. that buggy for example is a wild build and is super impressive but you cant put a golf cart motor in a tank and expect it to rip. and idk about 80% grade if you put that much effort into building a tubed chassis like that to have it roll around the yard at 5mph. doesn't need to do 100 but you cant put a golf cart motor in a tank and be like "SUCCESS"

Looks like you need something to keep your knees in if you roll it. Gullwing style cage doors would look amazing on that thing and should be pretty easy to make. Lil gas rams like the ones that hold open hoods or tailgate glass would be cool too cause then they'd stay open till you pull em shut. Also, it might be a good idea to make some removable thin aluminum/steel or plastic paneling to keep out the sand/dirt/mud and don't forget looking good while they're at it. 😎

[@geoffreyjones2000]

[@carson901]

In addition to stiffening the suspension, it's seems also too high, now most of the acceleration energy/force is wasted in lifting the frame and stretching out the shocks . In resting position the angle of those rear beams should be almost flat, so they won't try to crawl under the frame, but push the frame forward. The frame is not that heavy with the engines on the rear axle basically. I suggest moving the shock position to the horizontal frame bar just above it and a little bit back. This will lower and stiffen the rear suspension a bit an is a relative simple fix. I really like your work, keep it up! :)

[@bluefire87HN]

[@bryduhbikeguy]

I think it's well earned a name.Looking down,with the left camera,it looks like a Mantis.Soo..Spelled this way on purpose.'Preying Mantis".It eats those bumps like they're nothing./The way that left engine took such a pounding,I'd guess it's more of a float bowl issue,than an idle.Hate to suggest EFI,as you've already done so much with this,but that seems the answer.Great Vid Chris.

[@Slane583]

Got to give you a thumbs up for trying original concepts and being largely successful. You messed up with your clearances on the suspension stroke for both rear engines but that is just a rookie mistake I am sure you will never make again.

You have a ways to go but the point is you are getting there.

[@MrDilley777]

First of all sorry I don't know your name but I for a long time now wanted a fully equipped shop like you have and I'm very impressed with the machining skills and fabrication skills you have. This dual engine mini buggy has the best performing suspension I've seen for mini buggies. What DOM tubing and wall thickness was in this build? I'm guessing 1" and 1 1/4" .120 wall? I do have a J D square air hydraulic tubing bender and Miller 180 wire welder with tubing notcher. I kinda think that it would be better to have one V twin motor with CV axles so that the motors aren't bouncing around, maybe a built predictor 670, they can be built to over 40 hp.

[@kecheacosta7582]

You really need to fix the problem on the buggy with the Honda engine

[@BaronBoar]

This thing is pretty cool, but after watching this video, I think a better dual engine independent rear suspension setup would have been to set up the rear dirt bike style. Engines mounted to the frame, and then each engine run to it's own swing arm, so that the engines aren't bouncing around like that. With what I am proposing you still have dual engine and IRS.

[@simplybeanjelly]

If you want to, make the front a-arms shorter, so that it has the same stance as the rear, that might limit travel, but it will stiffen it up with the dual shock setup because of there being less leverage on the shocks. As well as, because the rear suspension needs to be stiffened up anyways, you might wanna look into relocating the shocks and kicking them out further to the sides to allow for you to put bigger shocks in different mounting points on the swing arms and not hit the engines. I think that the reason the one engine wanted to die so much was because of the spark boot being broken, lower idle speeds may mean weaker sparks, and with the cable having to arc to the spark plug because the boot was broken may have caused your running issues. And for the air filter relocator hitting the ammo box situation I would just relocate the ammo box to sit higher or build a different mount for it somewhere else, maybe behind the seat? Anyways, this is seriously one of my favorite builds, and the lack of power may just call for an engine refresh, maybe stage 3? I know I said a lot in one comment, but I'm hoping you see it and are able to consider some of these suggestions :) anyways, keep up the awesome work Chris! I really love watching your videos, and these raw driving videos are a whole lot of fun to watch, especially when I hear you laugh and see you smile and know that you're having fun with your builds, cause that's the most important part! I really liked the helmet cam and the camera on the rear suspension btw...

[@iwantmypot]

You could temporarily remove the springs from the suspension so you can test the full range of motion. (in the shop... not while riding it, obviously) As for the bottoming out... do you have a dial to adjust the dampening? The spring stiffness seems fine... just need the shocks to move slower.

[@Aiono777]

Hello, nice job, I think it would be better with higher wheels for handling(would also allow your chains to touch the ground), independent engines in the rear is original, it would take also an additional bar to turn more "flat" by creating a stop with a slight tension on the front suspensions (making them a little firmer, but less likely to capsize). I think it have little bigger wheels to stay in the category" buggy " (10"-12"?),your motors can do,better confort also.

to fix the air filter problem just put the factory air cleaner back on ...you wont notice any power loss .. taller tires and stiffer shocks may help with the front end bottoming out like it did. just shortening the the suspension travel would help to.. for the starter drive getting smashed id just move the shocks inside the space between the two engines ..the engine that was spitting sputtrring and refusing to idle thats most likely the needle valve getting knocked around (that unfortunately is the downside to a float and needle carb in an off road vehicle) you can fix it but if it happened once its most likely going to happen again.. keep in mind the carb isnt defective it was just never intended to be used as you myself and other youtubers are using them. factory tolerances can also be a contributing factor.. be cool welding
