RAZOR Ground force with a Predator 212!

[@thisisJim85]

Picked up one of these at a yard sale yesterday for $50. My kids are too young to put an engine on it right now, but in the future I'd like to do something like this to it. You should definitely make a tutorial video of this.

[@justinc9911]

good frame had one as a kid and its been 11 years now its rust free and still in good shape I recently welded a 80cc chinese engine went super fine good stability and only thinng is i got shocked by the killswitch while riding in rain lol

Did you see the razor dune buggy I have?I put a 212 on it. I have a garage full of go karts and I really love what you did with your razor.

[@321fabrication4]

You have a dune buggy one! I'm going to have to check this out! I just finished a Razor MX with a predator swap and a wheelie bar. Such a blast!

[@NickKautz]

You can supercharge the 212 with an amr300 or 500.

[@LittleMac907]

Haha that looks like fun. Good editing job. Keep up with the projects cousin. 🤘

So much fun! Can’t wait for the next build. I have some modifications to do to this one also.

Haha Thank you!

[@Mikey_Neuman]

how did you flip the axel for the sprocket to be in that that side

[@Typical_Americanpodcast]

I’m looking to do this myself, where did you get the cables and sprockets, did you put a centrifugal clutch on it?

[@InTheShop]

All of the arts can be bought on amazon or ebay. I used a centrifugal clutch. #40 chain, 15 tooth sprocket on the axle. The axle is 20mm so you will have to buy a sprocket with a 3/4 bore and drill it out to 20mm.

[@Typical_Americanpodcast]

Thanks for the info👍

[@jakechunasamy9642]

Big Bad Brad hey this to mine I feel very uncomfortable on it but it’s fun and funny to other ppl so do it on ur own attempt

[@Dav5049915]

Great time lapse of the work! I figured it wouldn't go anywhere with those tires, just spin em. Man that thing is crazy

[@InTheShop]

Dav5049915 thank you! They make “drift wheels” for them. They are on order for the next video.... along with a tad more power 😉

[@ovielluna2037]

Hi have a question what size of sprocket did you use on rear

[@owenmilam228]

I have the kart, engine, centrifugal clutch, chain and engine plate. I just need to find the axle sprocket. Any recommendations?

[@InTheShop]

Ebay or any go kart supply website. You need a 15 tooth 3/4 sprocket. The axle is 20mm so you will have to drill out the sprocket to fit over the axle.

[@SDDIGBY]

Hey where did u get the actual throttle not the cable

[@InTheShop]

I used a bicycle brake lever

[@SDDIGBY]

In The Shop hey and if their is a ball on one end and a wire line on the other end of the throttle cable which end would be the one to go into the brake lever? Thanks so much for your help!!

[@InTheShop]

The ball end goes into the lever and the wire end goes onto the throttle of the engine. No problem man! Keep me updated how yours ends up!

[@SDDIGBY]

In The Shop ok will do still getting all the parts thought it would be a lot more complicated thank goodness I ran into this video it made it a lot more easier for me to understand where all the parts should go! I still think it will be complicated but not as much anymore. Thank you! This is my first ever go kart build

[@InTheShop]

Awesome man have fun!

[@robby_4877]

What clutch, chain and sprocket set up did you use???

[@joew5559]

Before you destroy those carts you should put those wheels on a lathe they will center perfectly inside a lawnmower wheel or a small tractor wheel depending on the size in the height that you pick you can get a lot of fun out of this you just Apoxsee them to the wheel itself after putting them on a lead and making them a bit smaller to fit in the hub or rim any tractor supply has them

[@mikeymata3312]

are u gonna sale it?? that will be aswsome

[@thomasfortin8078]

Where can I find the right size sprocket to slide onto the axle?

[@InTheShop]

I had the sprocket kicking around from another project but www.mcmaster.com has just about any sprocket you can possibly imagine.

[@FindShindoHere]

I want to know how you did this because i have one and want to do the same thing

[@blakelindley2006]

Where did you get the 15tooth axle gear from?

[@treerexaudi]

Hello by any chance do you know how long the throttle/bike brake cable was? There seem to be a quite a few different lengths for universal fitment. 60" and 72" is two of them it looks like.

[@wayne3340]

[@TheDerek5512]

Is that stock sprocket

[@aliciat1532]

Bigger tires bigger tires!!!

[@InTheShop]

Maybe... I kind of like the small wheels and big power though.

[@aliciat1532]

How about big tires for some serious off grounding.

[@danp6427]

Where did you get the slipper clutch and throttle assembly? I have two of the drift carts with junk batteries, this project seems like the perfect use for them!

[@InTheShop]

Dan P the clutch is just an eBay 3/4” clutch and the throttle is a bicycle brake lever and a length of universal bike brake cable.

[@kilofrinzztv2370]

What did you use for the sprocket setup?

[@InTheShop]

I used a 10 tooth clutch and a 15 tooth sprocket on the axle. The axle is 20mm so you need to get a 3/4 inch bore sprocket and drill the hole out to 20mm. Hopefully this helps.

[@SDDIGBY]

Hey I have dismantled the motor and I am now on the axel part. I don't know how to pull the axel through the axel clamps what do you use to do this

[@InTheShop]

Just seeing this now. Did you get it apart? there are a couple of snaprings that hold it together.

[@SDDIGBY]

In The Shop no I have not tried yet don’t want to mess it up. How do I take the snapping apart

[@InTheShop]

You will need a decent set of snap-ring pliers

[@SDDIGBY]

In The Shop ok and then how do you put them back together

[@InTheShop]

Just reverse the disassembly steps. The snap rings go right back on.

[@danielbuilds7067]

How did you make the gear for the axel

[@InTheShop]

I used a 15 tooth sprocket for a 3/4 shaft. The axle is 20mm so you will have to open up the hole slightly on the sprocket by drilling it or using a die grinder.

[@Typical_Americanpodcast]

How many teeth did you have on the centrifugal clutch?

[@InTheShop]

Big Bad Brad I’ll have to check tomorrow. I can’t remember.

[@Typical_Americanpodcast]

Ok thanks for all your help👍

[@dp2459_]

[@jerardortiz9088]

Does it matter which way you face the clutch?

[@InTheShop]

Jerard Ortiz most go kart clutches are bi-directional and can be mounted whichever way works best for your application.

[@trdfgaming7664]

What chain you usung?

[@InTheShop]

#40

[@enriqueguzman6408]

did you change the axis star or is it the same?

[@InTheShop]

I had to change it to match the chain and clutch I used on the motor. The factory sprocket has very small teeth.

[@RUBYODOME]

I have the same one with an engine on it. I just made a dirt race track in my backyard. And I'm afraid it's too low and going to hit the chain and and sprocket. What wheels can I add that will fit. I was going to take some wheels off my lawn mower

[@InTheShop]

It’s very low. I’ve never tried to fit a different set of wheels on it so I’m not sure what will fit but I can try to do some research for you.

[@Todd_G_FPV]

Did u have to change out the sprocket on the axle? If so what sprocket did u purchase im looking into making my drifter gas powered

[@InTheShop]

I did change the sprocket. I used one I had laying around. I will try to get the specs and get back to you.

[@FrustratedBaboon]

That went pretty fast.

[@InTheShop]

So much fun. I’ll be making another video soon with some upgrades.

Thank you!

[@stclairstclair]

In The Shop, I'm going to give you a run for your money... I built the same Razor kart as you have done here, Then I rolled it from decelerating, doing 20, I'm a retired mechanic and am too old and fat to be rolling anything bigger than a joint, I was humiliated and disappointed all at once, dragging my kart home... 6 months has passed and I now possess the worlds most badass Razor Kart, Oh it's pretty, and I can hang corners like a demon, I successfully merged a Razor kart with vintage style race kart designs, I will post a video soon, you've been warned! 😊 (P.S. Most of my work is because of your build!)

How did you remove the rings that hold the axel?

How much to build one. Very interested for my son.

[@InTheShop]

You could probably put one together for $250-300 in parts if you get a good deal on the kart.

[@kyle1206]

What sprocket did you use on the axle?

[@InTheShop]

I used a 15 tooth sprocket for a 3/4 shaft. The axle is 20mm so you will have to open up the hole slightly on the sprocket by drilling it or using a die grinder.

[@jeffy1386]

I just bought one for my daughter, she said it’s too slow, how much money do I need to make it run faster for her?

[@InTheShop]

There are a few videos on KZbin that show how to hop up the electric drive. I wouldn’t advise building one like this for a child. This thing is a death trap.

[@tailopezpartners4060]

In The Shop I advise it, so the kid can get used to it and become Lewis Hamilton 2.0 👀

[@lsxjuan5574]

What # chain did you use ? And what sprocket size

[@InTheShop]

I used a #40 chain. I can't remember the tooth count. I'll check on that tomorrow. It is a 3/4i.d. sprocket though.

[@lsxjuan5574]

Ok thank you man. building one myself using your video

[@InTheShop]

[@meboy3513]

Top speed?

[@mrgunz6302]

I bought one yesterday for $50 I want to upgrade it like this but I will need specific details if you can do that will be great thanks

[@InTheShop]

Pretty straight forward and really fun. You will need a 10 tooth clutch with a #40 chain, a 15 tooth sprocket for a 3/4 shaft. you will have to drill the sprocket out to 20mm to fit over the axle. I made the motor plate with my plasma cutter but you can buy motor mounting plates on ebay or places like gopowersports.

[@rickjames2764]

Where do I get one of the 2wd axles?

[@Todd_G_FPV]

Order one from the drift kart not the go kart its keyed on both sides

[@extremecookingwithchocolat3081]

[@davidcoalkey6074]

You think your shop is a mess you should have seen mine before I cleaned it up a bit last week.

[@InTheShop]

I go through phases. Sometimes I like the place spotless and can’t stand the mess. Sometimes I’m glad I have triples of most of my tools because they are spread across the shop and the place looks like a tornado hit.

[@TedTucholski]

wonder how long before it breaks ?

[@InTheShop]

I’ve been riding it off and on for the last two months and nothing broke yet. It’s actually pretty stout. The only thing I need to do is put a jam bolt to keep the motor back because no matter how tight I bolt it down the motor slides forward and loosens the chain. I’ll have another video coming very soon with the kart.

[@xyasaki6383]

FYI for anyone doing this it takes a alan wrench for most of it

[@InTheShop]

Yes it does. Thanks for watching!

[@nswiss19751]

What gearing

[@SDDIGBY]

He does anyone know how to add a sprocket to this go kart in the video or can I just use the sprocket that the kart comes with. And how do I attach it? Or how to bolt it

[@InTheShop]

15 tooth #40 sprocket for a 3/4 shaft but you need to drill it out or use a die grinder because the axle is 20mm

[@SDDIGBY]

In The Shop so I need to drill the axle or the sprocket and what do I use to drill this

[@SDDIGBY]

In The Shop this a a lot to ask and would be a huge favor for me if you could make a quick 4 minute tutorial on how to do this I am just not very comfortable with how to do this and I am a little confused. Thank you for your patience

[@InTheShop]

You need to drill the sprocket out. The hole is not big enough to slip over the axle

[@SDDIGBY]

In The Shop ahhh ok thank you so much and would I then need to bolt it down or just position it right so that when the kart is moving the sprocket will not slide.

[@BrianCouture5446]

Can I hire you to build me 2 of these? I am in Central MA. This is so killer. I would buy all the parts new.
