You need to take off that restrictive muffler and remove the governor if it's still on, there is so much wasted potential, this should definitely be a 40+ kart, with the torque converter!
@@zed4me lol I know the struggle. I bought a Coleman ct200u and jacked the 196cc Hisun way up. Full governor delete, performance carb, intake, exhaust, 22# springs, CS Grind cam, PVL flywheel, 32 degrees of timing, gapped Autolite race plug and an ARC billet rod all through a TAV 30. It is super loud and sounds nothing like a farm implement, she honks too! To stay on the low I would recommend a Tillotson PK-1b carburetor with an intake ($26 for carburetor, $25 for filter kit), remove the spark arrestor (crappy baffle) from the stock muffler (not too much louder), Autolite race plug ($6), largest rear sprocket you can fit (with chain on it, leave an inch of tire side wall) and then preload your TAV 30 to the second setting. This will increase your low and top end without much noise. Now, as for the longevity of that motor (with the governor properly removed from the block) it is going to be necessary to put in a billet piston rod with better bearings and oil clearances even more so than upgrading your springs so you don't unseat a valve and bend a push rod because when that piston rod fails (it will ) it is going to punch a 2 inch hole in your block or the cheap flywheel will stress fracture and explode after becoming unbalanced from the higher RPMs. A PVL aluminum flywheel is about $60 vs over $100 for a billet model. As long as you add 4 degrees of timing with an offset key and install it properly, it is race proven and will handle something like 17,000 RPM for an hour. Your stock motor pushed around 3400 and a governor delete goal is 6700-7000 which nearly doubles power/torque if done completely. I had a friend who blew his Predator out 2 times before he bought one and left it alone. A lot of people think that governor is just some sort of thing there for other applications and doesn't matter. It's not. It is there because the rest of the engine is not designed or built to keep up with its own potential therefore shortening the life of the motor. You already have a sweet cart, TAV 30 and a goal. Save up $100 or less for another motor, break it down and build it. It's not hard, practice placing bolts and things back in threads after removing parts. It's by far the coolest, man card approved puzzle you can put together!!
i made one without clutch and i tried to use it without a clutch but i dropped it and the wheels were spinning so fast the kart flew off and hit the neighbours wall and now i have to rebuild the frame.
Loss of top speed is probably your gearing. If RPM top out, you are geared too low. If RPM are too low, and you are not heating the peak of the power band, you are geared too high.
This was a really great video, man! I've been wanting to throw one of these CVT converters on one of my two mini bikes. We race them only once in a blue moon. Lots of low speed, all clutch riding. Not too good for those little Chinese clutches! I think I'm gonna buy one and rig it up now! Thanks for the video man. Subbed!
The belt torque converter is smoother takeoff I find than the centrifugal chain clutch. I used both on my 196cc bicycle and the chain one I broke spokes but the belt one not as many.
keep the 12 tooth on and change your drive pulley on the the jack shaft to a 6 inch that will give you speed. if you have a 7 or larger that is mainly for torque.
I have a 420cc kart with a 40 series torque converter. You can check my page to watch it drive! I would recommend going with the torque converter but watch the video and tell me what you think.
If you are slower with the CVT that means you changed the final drive ratio from the start. A better test would be to keep the final drive ratio the same as the clutch arrangement. If you then are slower with the CVT it is because you ran out of engine power at a certain speed/rpm. In theory you should be much faster with a CVT. For this test what was your tooth count on the CVT and rear sprocket?
I want to do a tourque converter and then do a crazy small axle sprocket to go really fast top speed, but I’m worried about the brakes on my go kart. They are nearly nonexistent. Anybody have any recommendations?
It depends what skills you have, If you have bolt on replacement skills or fabrication skills and equipment. I've found sport quad rear brakes to be an easy and cheap upgrade. The problem with small sprockets is you lose acceleration and off the line power. Think of it like a 21 speed bike and how hard you have to work to get going in the higher gears. Too small a sproket will burn up the clutch or in the case of the torque converter setup it would cause excessive wear on the belt and the clutches, it will also over work the engine
Smaller driven sprocket for higher top speed not larger. It's also taller rear tires for higher top speed. A cvt makes a smaller rear sprocket painless. Most of the go cart cvt depends on belt slack for a clutch. The belt slack prevents you from using the low end of the pulley. If you combine a cvt with a centrifugal clutch you can get much better launches. That is how Honda set up the gy6 transmission. Though admittedly they did it backwards.
Man that Lifan 200cc motor would be a great addition to your build. I love your current setup, but if you really stop to think about it the weakest part of the build is the motor. Stacking another 3000+ rpm on top would fix all your issues with speed as well as getting a more even response throughout the range. Granted the 200cc has its own gearbox so it would undo some the current progress...LOL Cheers, looked like a ton of fun.
Shower thoughts: I wonder how well a GPS can keep track of how fast you're moving if you start to climb a steep Road, imagine looking down from the sky if something is moving partially upwards the more it moves upwards the slower it looks like it's moving so how do satellites see that, not sure if I explain that clearly enough but God damn it I'm not an idiot lmao

I have a torque converter but when I started my go-cart it took off and rammed into my siding of my house and bashed it in my go-cart is ok though but why didn't my go-cart sit still and idol instead of taking off?

What engine inside sprockets were you using when you did a run with a clutch? I have a 196 mL clone motor with a Mikuni 22 with a 12 front and 60 rear and Im 250 lbs and I hit 40mph.
I use to run a kid's fun park (FUNWAY USA ) in Foxboro and E Bridgewater as well as F1 Boston... for shits n giggles I took off a 6hp off of one of the kiddie carts and installed a 13hp. ... out of the 6hp too speed was close to 28mph... once I got done upgrading the SHIT out of a kiddie cart .out of a 13hp and some gear munipulation and a more breathable muffler I could get that cart up to 60 mph out on a straightaway. ..trying to corner couldn't be done without rear kickout. ... but was extremely fun.....! Good times. ...!
Hum..... on the motorized mini bike build i did a while back. We hd a 10t to 60t clutch chain loop to the motor. Then we added a tc same 10 to 60t sprockets. Had nice even takeoff and 15mph higher top speed. Cause it starts out low and ends up spinning the 10t 2.4 times every 1rpm of the centrifugal clutch
I found this old 1968 clinton engine with a built in 6:1 speed reducer in our barn. 1 cylinder and with the speed reducer outputs break 104 ft pounds of torque. It also weighs 116 pounds tho. Lol

spikeman dan there are two sprockets one in the front and on in the back. If you want a higher gear ratio you put either a bigger sprocket in the front or and smaller sprocket in the back and if you want a lower gear ratio you get a smaller front sprocket or bigger back speocmet
Glad someone asked instead of assuming a torque converter/CVT is all about "speed" (not the guy in the video, obviously he understands the true concept as he stated facts in the video) When you use a centrifugal clutch, you have what's essentially a "static" gearing ratio. To put this into perspective, imagine having a 2 speed manual (stick shift) vehicle, and imagine you could only use 2nd gear. This would essentially be static gearing, and would yield the result that depending on the gearing ratio used, you could have extremely fast takeoff, and a slow top end speed, or the other way around, but generally losing either/or in trade-off during the process of finding the desired gear ratio to use. Using this same example of the 2 speed manual, with a CVT, you essentially have a "dynamic" gear ratio that would be akin to you starting in first gear, and having the ability of switching to second, allowing not only better final drive gear ratios (the gearing from the driven pulley sprocket to the sprocket that drives the wheels itself) , but also a good mix of top end (top speed) and bottom end (takeoff speed) without sacrificing as much, supposing you find a good final drive gear ratio. This "gearing" is done variably (hence the reason CVT means continuously variable transmission, or as you call it "torque converter") by changing the driver, and driven pulley ride heights based on engine RPMs. When it first starts off the belt is riding down the inside of the driver pulley (pulley on the engine) and riding the outside of the driven (pulley at the axle/drive sprocket) and as the engine increases RPM the driver pulley closes in on the belt, causing the belt to start riding higher on the driver pulley (toward the outsides), which in turn makes the driven pulley at the drive sprocket open and the belt start riding lower (toward the inside), essentially "changing gears" as you speed up and slow down, continuously.
My cousin built a POS go kart that faster than that crap. only a little 5 horse but it FLEW but being the isiot he was he didn't put enough oil in it and it siezed.
Michael Supercharger thanks. I did some testing and found cvt will not hit the governor on a stock 212 so I put my built motor on a shifter kart frame with a clutch. I wasted too much time and money trying
Im out for the electric crap. But good video. Thanks for the info. But I've done the overpriced electric crap. Its bad in terms of distance and being out in the middle of nowhere.
the 12 tooth vs 15 tooth probably makes a 10+mph difference.
15 tooth is the limit for a properly working sprocket. 12 tooth will jerk the chain all the time and eat itself quick.
So like the less the tooth the faster the speed ?
Hung Ngo no the more teeth/ bigger sprocket or gear is faster but the bigger the gear the lower the torque
Tyler Truitt I’d say more than that
@@hungngo4790 larger #of teeth= bigger top speed but will take longer.
Less teeth wony have as high of a top speed, but will accelerate much quicker

My cousin built a POS go kart that faster than that crap. only a little 5 horse but it FLEW but being the isiot he was he didn't put enough oil in it and it siezed.
Man it's disturbing to Try to watch that time lapse footage!
You mean drive sprocket.
Its more like new t/c vs old not so good c/c.
do you know top speed governed?
I removed governor right from the start. With the torque convertor though, I believe the stop speed is the same.
+zed4me thank you. I think the same. I have a 16hp build same engine basically and I only hit 37mph with cvt
Vtec Banger You need a larger sprocket on the CVT to make more use of it
Vtec Banger a stock little 212cc predator toped out at 40mph on a go cart I had
Michael Supercharger thanks. I did some testing and found cvt will not hit the governor on a stock 212 so I put my built motor on a shifter kart frame with a clutch. I wasted too much time and money trying
talking hand
On lawnmower tires
Do stop signs mean the same in your country? 5:35 In Australia you need to stop and then go, whether there is other traffic or not.
this does not have three peddles??????
Totally automatic. No clutch pedal needed
Even shifter karts only have 2 pedals, they have a hand clutch.
a centrifugal clutch works by centrifugal force, search up how it works
why did no one hit like on this video?
Im out for the electric crap. But good video. Thanks for the info. But I've done the overpriced electric crap. Its bad in terms of distance and being out in the middle of nowhere.
What was your top speed?
Look at the video.
I hate electric gotta be charging and takes to long .. I prefer gas just add gas and go
5:37
Do Not do this in the UK!!!
is the engine still governed
Nope
