What motor can you use for a go kart

Thanks for your time. The spring when unwound should lay flat. My guess is that it seized up, or that the spring is toast. The TC only has straight shaft drives. Is my only option milling the crank shaft down? Even the most far-fetched advise would be helpful.

From what I have heard and have been told the tapered shafts were built for only what it was originally on. But would it be worth the trouble? It does have a Comet 20 series clutch. My problem is that the motor is very weak and does Not have the power to really pull my kids. What engine can I replace it with, without having to make or build new brackets and stuff, but still be able to keep the Comet torque box maybe just upgrade it to the 30 series?!?!?!

Predator cc engine is the cheapest most reliable swap for that. It has the same mounting pattern and crankshaft position, so you dont have to modify anything. The pto shaft is slightly shorter, but nothing a few spacers cant handle. Its night and day performance change. Might want to get a new belt and clean the torque converter for the swap too.

Hello, My son and I have a question. We purchased the springer upgrade in the kit from Go Power Sports. Not sure if you have the measurement from the bottom of the standard spindle to the bottom of the axle, or possibly the measurement on the top for the springer spindle bracket. The springer suspension was added by go power sports long after the plans.

Adam, not sure on clearance for back plate, but the 30 series is rated for up to 8 hp. If it were me, id keep the 30 series. You CANNOT put the 40 series drive and driven on a 30 series backplate as the center to center distance is not at a compatible distance for belts they are too close together.

Hii, I want to know how to use lawn mower engine for go kart. Can you guide me properly on this. Good luck. My dad and I built a go-kart with a vertical shaft engine when I was a kid.

From the engine was a belt that twisted 90 degrees. It then went to a shaft with a pulley on one side and a standard go-kart clutch on the other. From the clutch, the chain went to the sprocket on the tire.

I have a kandy b90 kart with all electronic everything, can I replace the motor that is bad with the predator motor and do away with the electronics. You will lose reverse, will have to buy a 30 series torque converter, and fabricate an engine mount.

Additionally, you will have to check gearing, and probably re-gear it. Or, you could fix or replace the existing engine, which is probably the better choice. Planning on replacing a Kawasaki Mule Diesel, with a Predator 22 h. I jist bought a kart with hand controlls and a 5hp tecumseh power sport motor.

The pull start on it is broke how do i know what to replace it with? Did the rope break? Torque converter with the same gearing provides much faster accelleration and a slightly higher top speed. Any thoughts? I have always wanted to get my hands on one. I recently found mfssupply. Thanks, and keep up the great work! The gear ratios are even better than the 94 though, too! Good evening, everyone, and let me say thank you to kartfab for the cool website! While reading through the question and answer section here, I see there is a lot of confusion over gear ratios, and more importantly, how to apply proper gear ratios.

To start, we need the basic fundamentals of gearing with sprockets. For our application, the drive sprocket will always be smaller, and have fewer teeth than the driven sprocket.

The relationship of driven teeth divided by drive teeth is called ratio. For example, an axle sprocket having 60 teeth is being driven by a sprocket with 10 teeth.

Here, the gear ratio is Lower ratios can provide more torque for acceleration, pulling, or climbing hills, but at the expense of top speed. Higher gear ratios trade acceleration and torque for higher speeds.

So now that you can calculate the ratio of a drive and driven sprocket, and understand what the resulting ratio will do, what do you do when you have a jack-shaft on your cart, and now there are 4 sprockets?

This is a form of compound gearing, and jack -shafts are commonly used to alleviate drive system space constraints, and to change alignment of the drive. Now you have a ratio, excellent clearance, proper chain wrap angles and chain speeds, and a much stronger and reliable drive system! And this is how the over-all ratio is determined. Find the ratio of the first set of sprockets. Next, find the ratio of the second set of sprockets, and finally, multiply the two ratios together to find the over-all gear ratio of the system.

Making torque multiply! Whew, sorry for the long post, but hopefully this will help to clarify some of the confusion in figuring out gear ratios! Ok so I just got this Chinese buggy 2 seater and I want to take it off road trails,medium hills, it has no drivetrain. I want neutral and reverse but also want it to get out of its own way. What would you recommend for my situation. Would this be powerful enough to do what I want thanks. However, the etc will work just fine.

If you go much higher in horsepower, you will not be able to use the comet reverse gearbox as it is rated for 16 hp. Hellos I want to put a v twin engine on a buggy I am building from components I got from a recked side by side, will a v twin engine blow out its oil if corner too hard or if I get it on an angel for any reason?

Thanks for your reply Any suggestions on how to go about it or should I not worry about it and see how it goes first? My son has a Manco fox phantom 2 seater go kart with a 10Hp cc Subaru engine. He wants to put a 22Hp engine in it.

Any advice you might be able to give on this would greatly appreciated. Thank you. The first thing I would do is take off the existing engine 4 bolts and measure the bolt pattern on the mounting plate of the go kart. Next, measure the bolt dimensions found in users manual of 22 hp predator.

If they match up, you can pull it off. If they dont, you need to get a new motor mount fabricated. If you have a manco and it has a 10hp engine on it, it likely has a 40 series torque converter, which is only rated to 18 hp. Thank you for your prompt response. Safety is our number 1 goal if we decide we want to move forward. Are there any alternatives to using the 40 series torque converter to compensate for the extra Hp or would it be in our better interest to look into an 18Hp engine?

I know the 40 series is more than twice as much as the I will be going off road on some trails but will be avoiding as much mud as possible. Would a cc serve better than a cc and should I try to get a torque converter or if I gear low enough or and use like an Inferno 10 tooth clutch, would that suffice?

I am putting s Koehler 27 hp v-twin in my go cart. Any ideas. I apologize in advance for the noob questions. I bought my 14year old daughter a Chinese dong fang Jaguar go kart that came with a cc motor electric start, forward, neutral and reverse. The and even had electric start. So my questions are: 1 What might I do to the Chinese motor to pep it up and help it up hills? Ok so i would just re-gear if you are worried about torque.

On the output shaft of the transmission there is a small sprocket on it. I would check to see if you could get a sprocket with fewer teeth on output, or a sprocket with more teeth on axle sprocket. It will be a little slower, but have more torque. Im afraid if you upgrade to the or , the drivetrain wont handle the extra hp. It may be possible for use a predator, but you lose electric start.

Might want to try a honda gx with electric start only if old and new engines are compatible with mounting etc. I put a cc predator with a turbocharger on my gokart. How do you hook up a boost gauge to a turbo??

Hey hows it going i am starting my project it is a joyner cc frame 2 seater kind looks like a mini buggy but has no engine i am thinking about the cc 18 hp duromax but im wondering what kind of sprokett im going to need to pull my joyner to good speed also do i need another clutch because i do not want to burn my clutch?

Also what size of tires will i need for the best ride or will that not matter sorry for all the question is my first project so would lie to hear your thoughts thanks again. IIRC, Joyner is chinese made, and some models are well built. You will need to do compound reduction gearing, or you will risk burning up your belts as the optimal gear ratio is So, look up jackshaft gearing reduction or something like that and shoot for a ratio between and U can make crazy power with em if u know what ur doing.

Thanks so much for all the helpful info! New to carting and hoping for a little advice; we have a little Manco dingo that I picked up a predator and new torque converter for and the predator has been awesome.

Second, are there any additional mods or replacement parts necessary besides the torque converter? Any pointers would be much appreciated! Okay so a hp can easily reach mph just take out the governor, put in a bored out jet and emulsion tube, and maybe a torque converter for a little higher acceleration.

Which will put out more power a predator v twin or a Honda gx? And are there any performance parts for any of these engines? The honda beats it hands down every time. I have seen performance exhaust systems for these.

The best you could do would be to remove governor rev limiters are also on the magnetos, so you will have to get ones that dont have rev limiters , rejet, possibly get a bigger air filter custom adapted to the engine, and do the exhaust upgrade. I have seen some custom billet flywheels and billet connecting rods, but they are pricey.

Chromemoly push rods,heavier valve springs etc. What if I want 30 or 40 hp? With a torque converter too? Hi I just recently got a two seater with a predator cc on it I was planning on getting a new engine with atleast 15hp but then I saw where some people just mount two cc predator engines on one go cart what do you think is a better route. I want to be able to have good torque and still go up like mph.

Just get the predator and a bolt on 40 series torque converter and you are set. Also, for the total cost would I be better off to build a gx? How much hp can you pull from a gx with a full build cam, ported head, mikuni pumper carb, breather, flat top piston, etc. Thanks, good read. There are tons of performance parts for the GX You dont really need performance parts for a gx anyway, just get a comet torque converter and you will be set.

Hey Guy, Just wanted to comment on the v twin. I have had mine in a Yamaha g2 golf cart for 2 years now.

We beat the crap out of it most week ends and have had no issues. Are buggie runs about 40 MPH witch is tons fast enough. As for the 18 hp comment above,that test was a rear wheel hp. That is to say 18 hp at the rear wheels. Ours was on a dino and made Im going to start a you tube channel of how we made are golf cart and all the mods.

Look for Big Joes Garage. Coming soon. Cool man, thanks. Nothing beats a Honda, and it will always outperform and outshine the predator- hands down. Save up now get a Yamaha kt not the mods that fit it. Most of your friends will be scared to give it all its got. Hi, i have a yerf dog spiderbox 2 seater go cart an was thinking about putting a 16 hp powerland engine on it from ebay. It had a yamaha warrior engine on it but tranny went bad.

The rear sprocket has 40 teeth. Would i just need the one inch clutch on the motor an hook straight to the back sprocket? An how many teeth should be on the one inch clutch? I dont want a super amount of take off power. Sam, you need to put a 40 series torque converter on it or it will burn up the clutch.

Also put a 60t axle sprocket on it and a 10T jackshaft sprocket on the torque converter jackshaft. I have a gocar with balloon tires and have Briggs and Stratton5HP on jack shaft I ordered a predator6. Hey this Abdulah and I have 2 questions? So I want to build a go kart with push start button, lock, key-remote, control buttons, head lights, revers gear, radio.

V twin engines. Can I find v twin with electrical start from other companies, can I power other acc. I believe that this list should give you an overview of what the best go-kart engines are, but ultimately you must be able to decide which one to go for.

As a general rule of thumb, you should pick an engine based on performance and price. There is a sweet spot, but make sure that you know what type of go-kart engine you are looking for and allocate a budget to how much you are willing to spend on a go-kart engine.

Go-kart engines can become dirty relatively fast, especially if you own an off-road go-kart or a racing go-kart. Your engine can stain very quickly and be covered in grease, oil or mud.

I hope this review and buying guide was able to help you identify what the best engines are for go-karts and that it also managed to give you an understanding of the various key components and aspects of a kart engine. I hope that this article has made your buying decision easier and that you were able able to find an engine that suits your performance and budget. Happy racing! It was worth reading this article.

I was needed a racing engine for my Go-kart. You provide some great resources for Go-kart racing engines. I was a little skeptical about my Air filters. How often do I need to change my Go-kart Air Filters? Thanks for your generous comments!

Glad this helps. With regards to air filters, for leisure useage I clean them after about every 10 — 12 hours of use. I know people who do this after every race depending on where they race.

Really appreciated this. My brother and I are building one for off-road and we are two big boys. We were looking at a 18hp duro max.

That sounds like an awesome project! For single seater lightweight karts, I would say 6 — 12 hp would suffice. For larger, more powerful ones 12 — 18 hp would work for sure. The Honda GC is an air-cooled 4-stroke engine that is more than sufficient to build a go-kart or to replace an existing engine on a go-kart. Sure appreciate the article! It seems to be the smallest engine in dimensions and I have limited space on my project. Thanks, David.

You sure can! However, just make sure that the engine measurements are workable for your project. Also check the specifications of the aftermarket components and see if they are compatible e. Tilly for the big dogs with deep pockets! I would check the chain tension and clutch condition.

Accelerate your kart slowly on a stand so that you can inspect. No offense to your list but the tillotson should definitely be on here as it is in fact the better than any engine on this list. Hey Shawn! I have heard about it but never had the change to try it! I will give it a try, review it and rank it in the next update. My goal with this site is to share valuable go-kart racing information through guides, articles, reviews, track details and more.

Hi Allen, Thanks for your generous comments!

Hey Tyler! Hi Timothy, Yes, that would be sufficient! Have fun! Snow blowers have a tapered crankshaft output. Hard to match up a clutch. I have a Honda GC 5. It will start and run, but the engine internals will not be lubricated properly and will quickly lead to seizure. This is because most small engines are splash lubricated by the engine oil. Two-stroke engines are smaller, lighter, and have less moving parts than a four-stroke engine.

They are also simpler and cheaper to rebuild. Some people like the sound of a high rpm two-stroke, some people don't. When karting first began, two-cycle engines were very popular. They were lighter in weight and capable of higher RPM's. The power curves on these engines are best suited for top end racing and run up to 10, rpm or more. Pound for pound, a two-stroke with the same displacement as a four-stroke will make more power.

Keep in mind that a two-stroke engine may be good for propelling a pound person plus a pound kart , but will have a hard time pushing a pound person plus a pound kart. Most people find it's not a big deal. Some two-strokes don't even require a mix as the oil is injected automatically from a separate reservoir. Some people like the oil smell, some people don't.

Take into consideration who will be driving the kart and where the kart will be driven. Safety needs to be at the top of the list, especially if younger people will be driving. Any 5-hp engine with a few modifications should be more than enough power for a yard kart.
