Thanks that was a long time ago it was fun to build.

It's been so long I don't remember Internet searches and I got the 2 together I forget what company it was.

I'm sure other ones will work. Go power sports seems like they have one.

Had a lot of low end not much top end geared it to be about 40 it was quite controllable I sold it a long time ago it was fun there wasn't a whole lot of difference between an 13 horsepower and a 22. More weight with a 22 more torque but the RPm's are about the same. Was a lot of fun. Fun to build to.

I used to be able to get it at the local recycle center scrapyard.

@@ians1464 where they given to you for free ? If so im going to contact my nearest place lol

Thanks it was fun to make to make it lighter go with 4 Wheeler parts

The engines were new and stock

That was probably the most fun set up. Put a Mazda miata rear end on it and again when I put the slicks on it you could just drift in a field at about 40 miles an hour it was cool one big loop.

Out of all of these that I've made that red one with slick tires was the most fun drifting on grass.

No the belts are very different in width

That was a pretty long time ago they might be hard to find might have to find something comparable. That was fun completely slick tires are even better So easy to drift on grass and it doesn't damage it. With such a light cart the 40 series did pretty good way cheaper. The 420 is not as cool but did pretty good too. The RPm's are about the same the engines a lot heavier the 670 has more torque obviously but doesn't feel much different

Absolutely that's as centered as I could do it without a mill by hand maybe closer to an 8th it doesn't take much to through it off figured it out it works great.

I think that torque converter was just a 40 series. The duster 94 is very strong With the high range of gearing

I just had to see what it would do with that gearing certainly could gear it to go faster that was actually kinda reckless if something came apart i would have hit a tree I'd be dead for sure.

It did handle really well if you see one of my later videos I did break the back axle that would have been a problem

I appreciate that I did it all just for the fun of it it was a duster 94 I forget but I did have to change spring weights and add a lot more weight to the weights that are in it. I know I added the maximum amount of weight that you could. If you have a light go kart that 40 series torque converter would be enough. Especially if you had the Harbor Freight 420 13 horsepower. I change the weight and Springs for the 40 series 2

Completely depends on your gearing it has plenty of power put a big sprocket on the wheel it's easier to swap out sprockets on the clutch. Had the smallest socket that would fit on the engine drive and it would go a little over 20 and then bumped it up to where it would go over 40 still tons of bottom end that's as fast as I wanted to go on this one.

I appreciate that it was fun

Appreciate that thanks.

Thats the most fun part figuring it out

Just a cheap 40 series and it's geared as low as I could fit sprockets on. 40 roller chain I think 8 teeth on the front and the rear sprocket almost as big as the tire

It was #40 roller chain and sprocket I forget how many teeth but close to the size of the tire the front one was as small as I could go

I always wanted to do wheelies on these things too. To be able to do that you're gonna want a very short frame something made for a 5 horsepower Small tires no suspension in the front a weight thing put all the weight on the back and it's gonna be maybe A670 not sure you can do that with A420. Most lowest gears smallest sprocket in the front biggest in the back. Smallest that will fit on the front drive train and something closely matching the size of the back tires. At a minimum 40 series torque converter. Cars and camera did this I think they called it the Widowmaker

Yup the cart is exactly everything you described, short, no suspension etc I've seen karts doing wheelies with the 212 predators so the 420 has got to be able to do it, I would imagine so anyway. I guess we'll see when I'm done doing some mods to it and bolt it on my kart. I'll put up a video when I'm done🤞🏻

@@norcal8718 it's fun and all at first until it gets old all that weight in the back makes it turn like shit for the 700 the torque converter and motor cost its not worth it

How much more power did you get man did you do wheelies 🎉

I had different length belts and I spaced them apart depending on the length of the belt. I read it off of a website either the length between pullies or the tension on the belt or The paperwork from the torque converters

You don't always need one if you have a small light go kart 6 and a 1/2 horsepower especially if you stay on the road you don't need it. It acts like a transmission and changes ratio at different rpms. Big tires live axle engines with a lot of torque off road you're gonna want. They're not expensive. little 50CC scooters up to the big engine snowmobile's use them

@@ians1464 I have a 250cc Murray gokart 1 seater. Why do the sprockets never line up correctly? Got the motor on and I look down and the sprocket on the motor is slightly off from the axle sprocket

That's actually never been a problem. It's square to the front sprocket it's a 50 roller chain sprocket using 530 motorcycle chain. All the holes were done by hand or a drill press measuring as best as I could figure. The biggest problem I've had is not being able to take up more slack Started off with a tensioner on the bottom and then figured out that I had to put one on top to heavy duty trampoline Springs to keep it from skipping over the front sprocket when I let off the throttle

They're just standard riding lawn mower tires. I think maybe around 20" by 1250 probably ordered them on eBay as a built set they were not expensive and the hubs just need to fit a 1" axle pretty common. I got a flex proof axle don't think you can bend that has a zinc coating so it's easy to change the set up.

Stock 13 horsepower Harbor freight predator. I was gonna Add some mods to get a higher RPM I overrid the governor briefly and I ruined it didn't see much difference really. I think I remember getting to 5000 RPms It was quite a while ago anyhow I put a Harbor freight 22 horsepower 670 on there pretty much same top end a lot more torque. Really not that much noticeable difference it was just a lot of fun I sold it.

Thanks it was fun to make and ride put a 670 on it that was a little sketchy

I did and it works great I just had to cut and stretch the top ones cause they're too short and I ordered brand new axles because the ones had splines on both ends Plus they were shot and they're pretty cheap. Pulled it all from a junkyard for a reasonable price. The hubs Had extra metal that I cut off to save weight the bearings still seemed good didn't change those took off the rotors and any unnecessary weight. Pretty easy finding wheel spacer adapters for different log patterns or you could just use miata wheels. Tried to keep it as light as possible so when I made the rear tabs I used thin square tubing cut stuff that fit the pivot areas I think it was a total gym mostly

That was a long time ago I put a 670 Harbor freight engine on it but it's just all in the gearing I geared it to go a little over 40 and that was sketchy enough with the way the front end was set up

You mean how much did it cost to make or how much did I sell it for because when I sold it it had a duster 94 CvT and a 670 cc Harbor freight. Found the frame in bad shape good frame 75 bucks. Put Mini quad suspension on the front and a yerffdog suspension in the back. It certainly would be cheaper to buy something but it was fun to make

How much did you put into it total with the 420cc and how much did you sell for

@@ians1464 because man I’ll give you all the $ you need to build me one just like this haha I have a lot of stuff already like the frame /motor etc

I sold it you can buy the red one with the 750 night Hawk engine on it

@@ians1464 $$?

I think the 420 is the way to go for you with the 40 series torque converter cvt is fairly cheap. Take your time look around for a decent cheap go kart frame will save you 80% of the work. There will be plenty to modify with suspension mounting the engine live axel upgrade and so on. I've got some videos of exactly that started off with a 420 overrid the governor seized the engine put a 670 on it and an expensive duster clutch really not a whole lot different than the 420 to be honest. Mostly the cool factor of the 670 cost way more. The most fun is actually building it and figuring it out. This video here I found a perfectly good running Honda nighthawk the guy hit a deer sold the bike for a $1000 pretty much cut the frame out and left the motor in it was fun but it starts costing a lot. Practice with the cheaper 420 when you get bored with that find an ATV engine with reverse.

@@ians1464 Okay, thanks a lot. Also, is it possible to find a gearbox or something that you could attach to a 420cc engine that would allow you to have reverse? I know they make reverse gearboxes, but from what I have seen they are not meant for anything stronger than a 212cc.

Good deal that was the first video I made because I couldn't find anything on it. The aluminum arrows work great. I did have some inserts blow out roughen up the surface and try some jb weld the original 24hr stuff. Had a seal go out on my bow and I think I'm done with it

your video really helped, sad to hear that you have had a seal go in your bow, but to be honest you are I a better situation there than we are here in the uk, we have nowhere in the whole of the uk where you can take these things for service, nowhere will touch them. And there is no bejamin dealer in the uk that will touch it. interested to know where the seal has gone and how that has come about? If you do know that is, kind regards Matt

That 1 was it was fun too. Now it has a Mazda miata rear end with a Honda nighthawk 750 and 25" tires.

What are you trying to figure out

I wish I had put more adjustment in the chain

Kj Raycing has the best designs i just winged this the best I could figure

I am trying to secure/build an independent rear chain drive suspension

Thanks it was fun. Pretty much finishing up a 750 CC with a Mazda miata back end

Thanks did you see this 750CC Mazda miata rear still working on it a little bit

Not really the frame needed work but was only 75 bucks still a good start the 40 serious torque converter and Harbor freight 420 engine worked just fine on it. It was just as fun to figure out

I don't see why not

Yeah where did you get the engine

@@ians1464 the engine I'm using is from a pocket bike
