Ya bro that's cool you got trails to ride right by the house, gotta love that!! I just bought a new 420 predator to replace my 212 on my go-kart cuz I want the thing to do wheelies, so we'll see what happens. Appreciate your video👍🏻
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
Damn 3 years ago...only 350....and he made me smile whrn he said i put ya there so u dont fall over and his drift...bruh why da **** yall.not showing him more love
bad ass you build some bad ass go karts I had a silver fox 2 seater go kart I ended up putting a 200x three Wheeler motor on and it was bad ass I took it in the mountains in Tennessee with my boss and his family they have those bad ass side by sides and I could go every where they could go
Garyntara7788 Burbank hey thanks too bad you're not my neighbor I'd let you try them out. I finally got this one running today tried to make a video with my new camera I couldn't get it to work right. The factory jet was about .039 the ones that come with the upgrade are supposed to be .041 and 42. They didn't work had a drill bit that was 45 it didn't work the next smallest drill bit I could find was .057. It seems to be working pretty good it's pretty strong. I'll try to make a video of it tomorrow did you see the 670cc it's pretty cool too.
bad ass video thanks for sharing with us I have a 1994 manco dingo buggy 8hp Briggs Stration I have had it since my 5th Birthday bought it brand new my 12 year old son rides it now but off road go kart buggy's are a blast they are fun in the snow and can go anywhere a sports quad can go we also have a 1983 Honda 200s three wheeler I ride a 1996 Polaris trail boss 250 my wife rides a 2008 Baja warrior 200cc trail bike torque converter belt drive converted street legal I ride with my cousin on his Kawasaki ninja 250r a friend on his Honda grom 125 a friend on a 250cc scooter and a good friend on his motorized bicycle
Tara Burbank this is my fourth one that I've put together they get a little bit better as they go it really pays off to think it through so that things are adjustable and there strong. The first one was a free mini quad that I put a six and a half horsepower on with a torque converter that was pretty squirrely. And turned it into a low riding 3-wheeler which is pretty cool then the 670 and then this one. Was just out on the 670 today it is a crazy blast with slicks on it
I put a 670 on it everything being equal no comparison in torque. RPMs similar top end the same. Now I'm trying to squeeze the proper clutch on it at duster 94 with about a 10 inch Drive wheel on the back
Brandon Matz I geared them as low as I possibly could I wanted them to burn out on pavement I think to do that you have to put a motorcycle engine on them with gears. But they are a blast still
It says the factory setting for a 40 series comet clutch is 1600 RPMs. It's slightly engaging at too low of an RPM If the knockoffs are the same it should have heavyweights I'm going to try The Red Springs which are the next stronger if the ones that are in it are comparable and buff the inside part of the clutch so the parts are smoother maybe it will last longer before it needs to be taken apart and lubed.
Cool go-kart though i like em so the only way to fix the creeping is to turn the idle down a 1-2 half turns (turn the screw out ) and the creeping is fixed the way how to turn the idle down there is a plastic like screw on the carb (top) NOT BY THE CARBORETOR BOWL just turn the plastic screw out 1-2 half turns and the creeping should stop I had the same problem on my go-karts I just turned the idle down and it stopped love ur go-karts if u have any more questions just ask (gopowersports.com) have a great day
That's probably what ended up happening but what I've done is put in the Red Springs and then the high-flow exhaust high flow intake had to Jet it out and then had to adjust the idle so that's probably what happened towards the end
The 40 series torque converter is locking up on me maybe I just need to clean it I've got it geared to top out at about 25 it gets there real quick though
Ian s all the 40's have the same problem. When ur in thr snow i recommend silicone lubricant otherwise use dry lube. But expect to open it up and lube per every 4 hours of use.
Eldin thanks that kind of sucks though I think I've got to unbolt the engine and move it a little bit oh well at least the jackshaft and chain is going to be aligned still I wonder if heavier Springs would help.
What size chain and sprocket are you using? I'm curious because I'm in the beginning stage of swapping a 150 to a 420 on a Trailmaster XRS. Have the motor and mounting plate so far. Probably won't complete the build for another year, if finances permit.
That’s a cool go kart. I was looking at a open box electric start engine just like your for only $299 shipped so I was looking to see what I could use it for and found your video. I doubt I’ll but the engine though.
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.
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.
ShadoWind360 I think I just needed to turn the idle down a little bit. Plus I put in heavier Springs in lighter weights and that gave it a stronger take off plus I just made another video and put a 670 on it
Most yard cards have about a 6 and 1/2 horsepower. If you have both Wheels spinning a live axle your best for off-road get a CVT or a torque converter a 30 series would work with a six and a half this one's a 420cc and I've got a 40 series yes they have belts. The easiest thing to do is buy the plate that attaches to the motor and it will have the correct belt tension
Ian s Thanks man the reason I asked is because I already have a 212 CC on A smaller cart and I ordered a 420 CC from harbor freight Just wanted to know where it all came within if I had to change some things I’ll ask any more question when it comes in though
It doesn't hurt it to have the drive pulley and driven pulley backwards like that? Meaning the engine pulley, the flat side, is against the engine and the bottom pulley, the flat side, is opposite.
It can probably be run both ways I've just never seen them run any other way. I know it does matter if it is designed for a belt that has different angled sides you have to then make sure the belt is on the pulley right.
@@ians1464 that makes sense. Mine has an angled belt on one side, and from what I've been told is to make sure the angle is against the beveled side of the pulleys or I'd eat the belt up in no time. Thanks for responding.
Thanks but I put a four-wheeler front end on a bigger one with a 750cc Nighthawk the steering was good but stiff so I put a Toyota Prius electric power steering on it and it's great
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
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
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
With a torque converter yeah get a 40 series and with a live axle the bigger the tires the more traction. Something like riding lawn mower tires should be plenty. Unless it's wet then you need aggressive tread
@@shark11175 well the other Harbor Freight engines rev to 3600 RPMs I broke a 13 horsepower at 5000 RPMs probably bent something the 670s Rev to 4000 RPMs and I'm okay pushing it to 4300 maybe five. Get a 10 $15 Amazon RPM hour meter. I had to adjust the spring setting for the governor it wouldn't even move and I wouldn't know how to adjust it unless I had the RPM hour meter but you have to put stiffer Springs on until you get the right RPM where you want them make sure the Springs are loose because if it pulls on the arm at all it's going to make it take off and rev High. The 22 horsepower does have way more torque than the 13 so you can just gear it to fast it'll still have bottom end torque. Weight matters also obviously the lighter it is the better a cheap 40 series torque converter will work. Might just have to play around with gears I've got industrial 40 series chains and gears on this one
@@shark11175 oh and it's easy to open up the air intake leave the pre-filter off and leave the side cover off for 1 . Seems like they run a little Rich so it should be fine . I would put better Japanese spark plugs on it and you're probably have to modify the exhaust because it blows in the wrong direction. An easy way to adjust the exhaust is cut it off at the flanges order some flex pipe from Amazon.
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.
With a 670 on it and taller gears it goes over 40. The front tires hop it 40 I've got some stiffer shocks coming in and hopefully it works well the cancel that it's got enough bottom in I can easily tear it to go faster I'm not sure if that's a good idea though. I think the 420 geared the same would be similar at the same RPMs this one definitely has more torque. I had have your Springs that I was going to put in I override the governor to see if it would be worth it to bother taking the governor out and I just ran into a couple of times got it up to 5000 RPMs and now it won't start I think I may have bent a rod wasn't terribly impressed though I think it was because the gears were so low. Because you know that doesn't change the torque just the top speed with the RPMs to send you the rated at 4000 RPMs and I'm comfortable pushing it to 4300 with a cheap hour meter / RPM gauge
Daniel Tristan it's just an industrial 40 series roller chain sprocket I get them on eBay and Amazon you want to be as centered as possible or it will wobble. Most have a hole in the center already so take a thin piece of metal and drill it with your pilot bit that's in your hole saw and then Center that in the middle of the sprocket as a guide. Using the heavy duty roller chain and I've got 530 chain on my 50 Series sprocket on my other go-kart.
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.
Rasta B Tv thanks just put the torque converter back together I polished the inside pieces it was sticking and lubed it with that expensive comit molly lube put some stiffer Springs in it so it won't creep forward I'll put it together today and see what it'll do
Ian s I've taking this 40 series apart a couple times with the same issues. I completely removed all the lube no dry lube either only some gear lube on the brass bushing it seems to work well that way but it still has a delay. I'm considering stronger Springs. Thanks be blessed. Rastafari.
Rasta B Tv I just got it back together and gave it a run with the red Springs you can see they're thicker than the springs that it came with it still creeps I think I'm going to go. The next size up. Plus I saw where somebody put grease inside that clutch I know it's not recommended but he said he hadn't had any issues since
The way I geared that one it just got up to a little over 40 you certainly could gear it higher it was sketchy Beyond forty the one that I've got now with a 750 Nighthawk will easily go 80. I could gear it faster but I don't want to die
Ian s what do i need to do to gear my go kart faster? Currently im running 10t clutch and 54t axel sprocket. I get 34mph max with my 212 but i need more mph. Thinking of going to a 420
Awesome kart! I like the detail you put into it. Did you ever figure out the creep issue at idle. Is it possible the belt was set up too tight? That 420 really seems to have a lot of power!😁
It was in pretty bad shape when I got it. No suspension or axle at all. I put a mini quad frontend on it and a yearf dog backend. I sold it awhile back. A yerf dog would probably be your best bet for the money
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
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
Nice build man! Love the burnout and donut footage! Cheers!
Thanks it was fun to make and ride put a 670 on it that was a little sketchy
Nice go kart, I like your construction and craftsmanship you put into it!

@@ians1464 I will thank you
Nice, do you have a link of the torque converter?
I think that torque converter was just a 40 series. The duster 94 is very strong With the high range of gearing
That’s a cool go kart. I was looking at a open box electric start engine just like your for only $299 shipped so I was looking to see what I could use it for and found your video. I doubt I’ll but the engine though.
Use a 212cc predator, best bang for your buck
What size are your tires? Im looking to make my own build and they look perfect
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.
Nice build!
Thank you you should see it with the 670 on it now the last videos the best footage I think it says something like 670 go-kart don't be a sissy.

Bad ss buggy!! What size bracket are you running it looks large and where did you got it from?
On my gokart it likes to creep forward only when the belt is new, and after the belt adjusted from riding it, the creeping forward thing stopped
ShadoWind360 I think I just needed to turn the idle down a little bit. Plus I put in heavier Springs in lighter weights and that gave it a stronger take off plus I just made another video and put a 670 on it
Do you need a belt and a pulley system for this or will it be fine without it just a little bit slower, and if so does it come with it?

Where do you get the sprocket
Daniel Tristan it's just an industrial 40 series roller chain sprocket I get them on eBay and Amazon you want to be as centered as possible or it will wobble. Most have a hole in the center already so take a thin piece of metal and drill it with your pilot bit that's in your hole saw and then Center that in the middle of the sprocket as a guide. Using the heavy duty roller chain and I've got 530 chain on my 50 Series sprocket on my other go-kart.
how many hp?
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.
Yo nice 420 quad suspension is the best way to go. Check out I 670 build on my new channel.
Be blessed Jah Rastafari.
Rasta B Tv thanks just put the torque converter back together I polished the inside pieces it was sticking and lubed it with that expensive comit molly lube put some stiffer Springs in it so it won't creep forward I'll put it together today and see what it'll do
Ian s I've taking this 40 series apart a couple times with the same issues. I completely removed all the lube no dry lube either only some gear lube on the brass bushing it seems to work well that way but it still has a delay. I'm considering stronger Springs. Thanks be blessed. Rastafari.
Rasta B Tv I just got it back together and gave it a run with the red Springs you can see they're thicker than the springs that it came with it still creeps I think I'm going to go. The next size up. Plus I saw where somebody put grease inside that clutch I know it's not recommended but he said he hadn't had any issues since
Top speed?
The way I geared that one it just got up to a little over 40 you certainly could gear it higher it was sketchy Beyond forty the one that I've got now with a 750 Nighthawk will easily go 80. I could gear it faster but I don't want to die
Ian s what do i need to do to gear my go kart faster? Currently im running 10t clutch and 54t axel sprocket. I get 34mph max with my 212 but i need more mph. Thinking of going to a 420
Man can you help me restore my go kart? I’m in SoCal.
Not gonna lie, that thing looks scary to drive
It starts feeling sketchy over 40 I'm sure it has to do with the steering geometry. The 750cc runs true at 75
Anyone have warranty on a 420 cc predator?
Can I buy this?
I sold it you can buy the red one with the 750 night Hawk engine on it
@@ians1464 $$?
Just put a 670 on it
Awesome kart! I like the detail you put into it.
Did you ever figure out the creep issue at idle. Is it possible the belt was set up too tight?
That 420 really seems to have a lot of power!😁
Thanks it was the engagement of the torque converter the Springs and the weights. I sold this one almost done with the 750cc.
What kind of go kart is that . I’ve always tried finding a simple adult size go kart with a little suspension
It was in pretty bad shape when I got it. No suspension or axle at all. I put a mini quad frontend on it and a yearf dog backend. I sold it awhile back.
A yerf dog would probably be your best bet for the money
How much
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
anyone else thought he was black when you heard his voice?
So it’s not a stroker lol
This prob cost more than my first car
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
Dude wear a helmet that ain't no 5hp
