- Coleman CT200U-EX Torque converter jackshaft comparison /install
Tested the Coleman CC200U-EX minibike with a jackshaft and then installed a torque converter to compare the difference in performance.
The engine is a 196cc with a VM22 Mikuni carburetor, header pipe, and a 7-degree flywheel key.

Black66 I Really Enjoy Your Comparison Videos. Thank's And Keep Them Comeing
NICE! I actually wanted to know this. Was thinking about it the other day.
Thanks for all the work you’ve been doing
Thanks, man, I really appreciate you saying that.
We put a jack shift set up on a Tillotson 225 and that thing had great acceleration and topped out at around 50mph
Thanks for all the info! I just finished my first mini bike but my neighbors call the cops when I take a lap around my neighborhood! Oh well……….. please keep the videos coming !!!!!
Thank you! Maybe A quiet muffler LOL I'll keep the videos coming.
@@Black66 a recommendations on a quiet muffler? :)

Tested positive for the cough yesterday so no working on anything this weekend got parts in just been in bed for 2 days feeling better then I have in 48 hours but at least the mini bike community keeps me entertained 😊
You will be back at it in no time!
Get better brother
@@nickclashez thank you sir
Hope you feel better!
@@27Zangle was rough stuff took a month to stop coughing 😕
Been waiting for this one!! Thanks
I noticed that with the top speed run it was faster + less rpm. I’m definitely sold on the CVT!
Thats a sick ass intro with the drone dude!
Thank you for sharing I enjoyed learning. I’m new to mini bike world I have much to learn I want a hard working simi fast bike
Thanks for the information 👍🤠
Very good you mention driver pulley and driven pulley alignment how was rear sprocket and small sprocket alignment ? How did you align those two sprockets ?
NICE JOB!
Thanks!
I was gonna fully build 212 but after seeing this I changed my mind, I got the same one it had a bad carb and tank, it did run. Ordered new carb an all for it, going to see if it'll crank now with new carb, and uf Sonim going with this route
Did u ever get it to work man?
I need to put a torque converter in mine!
Respectable for the 40T rear gear. I am doing 44 with 10T front and 50T rear. I am gonna try it with the 60T for the desert romping I do.
Any update?
Quick question for you sir, when you installed the three quarter inch sleeve on I didn't see you put on key. Did you not use it? Or do you use the one that comes built in?
With the torque converter, can you change the weights in it like other torque converters on other bikes? The Honda Ruckus comes to mind.
Another informative video Keep it going
Thanks !
Awesome stuff! Was going to go with gopowersports package but I didn't want to cut anything off the frame. This way is perfect AND cheaper.
I'm also looking at the go power sports package, which one is this?
@@lifebythehorns the assemble yourself version, takes a bit more finagleing but gopower is charging alot for less of components. Plus the engine raiser just looks 👌 compared, better be for that price.
If you have an angle grinder and drill just buy the shaft adapter and almost any 3/4 torque converter off amazon.. then cut and bolt your own raiser with some 1' square stainless steel tubing. Can do the mod for less than 100$ that way.
Would have now that i already did it this way.
Also, he makes the drive adapter look way easier than it is lol
@@brettb86 wow thanks for the info! Very helpful I think I will do that.
@@brettb86 do you need a new chain also?
@@lifebythehorns new drive length so new 420 chain. Get extra lengths n cut em down to size
SO much info on this channel! I have the same bike and just installed the Torque Converter. I'm about 235, and looking for the right ratio for hills and speed. Currently stock 10tooth to rear 50tooth. You mentioned you already had the 40t rear before your speed test. Any recommendations?
For a heavier rider I would go with a bigger rear sprocket .Check out the playlist for many engine and part combos with this bike.th-cam.com/video/jHf9yJmaZLA/w-d-xo.html
Great channel. Great channel. Editing content videos..keep up the hard work..greetings from OH ...new sub👍
Thank you !! I appreciate it. Thanks for watching the videos.
Sounds better tooi
I like how your driver gear just slides right over the shaft adapter. I’ve sanded mine down an still it’s tight as heck. Literally have no idea how to get it too just slide on.
I had the same problem. Luckily I work in a machine shop and chucked it in a lathe and machined the adapter to fit the driver.
What upgrades did you do to get the stock 196cc up to 40+ mph? Thanks for the awesome video.
Thanks! Check out the CT200U-EX playlist for all the upgrades and many different combos with this bike. I think we actually got it in the 50s with the 196. th-cam.com/video/X0SmAZJ6qW8/w-d-xo.html
Sweet comparison thanks for doing the comparison video. Since me and friends do more street cruising Ima be going back to jackshaft. Which one felt better for you? Also il be trying to upgrade to a 265 cam from a cl1 for my predator, you think the 18lb springs will reach up to 8000 rpm or will I need 22lb springs?
If you change your cam 22 is the minimum I would use.
@@xaviermccloud4586 ok thanks, I had the jackshaft before with a 38t rear sprocket. Have a predator with 18lb springs billet rod and flywheel with a cl1 cam and 22mm mikuni. did 52mph at 7000 rpm. I want a 265 hoping to get up to 8000 rpm and 55+ mph on my Baja warrior
@@srcobra50 You should be making more top end already. Maybe you need a bigger carb as well? Not sure.
@@xaviermccloud4586 well….I am heavy…about 270…I think the cam just can’t push more than 7000rpm. It’s cl1 cam on it currently
bigger springs would help and a bigger flat slide carb
Awesome video. Just got the 212 for my ct200u-ex and have some items in the cart on gopowersports. My question is where did you get the engine riser bracket?? Looks like gopower kit comes with a couple squared risers that don’t offer the forward backward adjustment that does.
Thanks! There are a couple riser mounts listed in the description of the video. Check out the CT200U-EX playlist for many engine and part combos with this bike .th-cam.com/video/jHf9yJmaZLA/w-d-xo.html

@@funkymonkifyd Thanks for watching the videos!
Hey! Love the videos very helpful! I have the exact same converter you do I bought the one in the link… my belt did break after a while. Do you have a link for a new replacement belt? I know there are so many different sizes.
Awesome! Thank you! here is a link www.gopowersports.com/30-series-drive-belt-203590/
Thank you!
Have you had to replace any belts yet?
@@michaelbentley7510 No, I install the driver with extra spacers. Check out this video th-cam.com/video/AR2vISEaTcc/w-d-xo.html
Doesn't changing the chain length also impact the torque ratio?
I'm sorry love ur Content but I gotta correct you!LOL its a CT 200 U EX V Nobody ever says it rite when they do a video on this bike!!😆😅🤣 glad we cleared that up👍🏾haha
K i c k i n' a s s! My 200ex only has zip ties on the inner Gov spring and the airbox drilled with 2 extra 3/8 holes
Does 30.7. 2nd best ridgid frame minibike in my opinion, But I LOVE my $599 RB200 (Coleman ReBranded 200 from Monster Moto) I def. need to torque- convert that one with a comet clone
Thanks! 30.7 is still pretty good. That's a lot faster than this one was when we first got it. Have you seen the video where I git the CT200U-EX up to 60MPH?th-cam.com/video/jHf9yJmaZLA/w-d-xo.html
On my torque converter the red spring I moved the spring to the rear hole and I gain one mile and hour
So the results are unanimous that torque converter is better for bottom end AND top end?
What adapter did you purchase for this and was it the perfect size of the shaft or did you have to cut it? Want to use an adapter so I can use the juggernaut on my Coleman ct200uex torque converter…..also how to you get the adapter off if you want to switch back…..thanks….love your videos…so helpful
No, need to cut it. Links are in the description for the parts used in the build. Check out the CT200U-EX playlist for more combos on this bike. th-cam.com/video/X0SmAZJ6qW8/w-d-xo.html
What are the washer things called you used to line up the pulleys and what size
Have you had good luck overall using those TC-Motor "mikunis" carbs? I am thinking about replacing my old motor with a predator 212 and would love to hear your feedback on if the carb listed in this video would work for my application?
I like the "Fake" VM22. They are easy to tune, and super inexpensive. You probably will get more power out of an actual Mikuni, but for the money there not bad. You can get the entire kit with intake and all for around $50 . Will work on a Predator no problem.
@@Black66 Awesome! Thank you sir. I'm trying to get my Manco Big Cat running.
@@johnp1804 That is a sweet bike!
Hey I’m new to this game but I have a completely stock ct200u-ex and have been wanting to install the torque converter. Can I just buy the converter kit, riser plate, and 5/8 to 3/4 adapter you linked In description and be good to go? Or do I need to get the mikuni and header pipe as well? Thanks and great video sir?
Thanks! You can do it without the Mikuni and header pipe
Where did you get the mount holding up the engine? I’m about to put a predator engine with a torque converter on the bike and can’t find a mount anywhere online. I’ll make one if need be but buying for sure saves time.
The links for the parts are in the description
Is your jackshaft stock because my mini bike the stock jackshaft one to 25mph and torque convertwr gets me to 45mph
I need a driveshaft keyway for my hisun 196cc so I can bolt my clutch back on. Any idea what size I need?
The jackshaft Was the 1st thing I got rid of I guess the torque converter works better on tall tires and I have a 40 tooth sprocket coming in the mail I will let you know what my top speed will be
Yeah what's your top speed with the 40 tooth?
What Allen screw did you use instead of the longer bolt it came wit to hold on the driver gear?
I picked the screw up at the hardware store . I think pretty much anywhere with a good bolt bin will have one .
What size is the jackshaft mount bolts
Awesome!! Where can we get the 5/8” shaft to 3/4” adapter like you used? I have the same bike and will encounter the same issue I presume. And what about the mounting plate? Where could we find that?
Thanks! I put the links in the description for the mounting plate and the shaft adapter
i swear you had a video on how to install your torque converter with the jackshaft mounting plate but i can’t find it 😩
When you use the vm22 carburetor, do you need an adapter or does it bolt right on?
Here is a VM22 install video. Also check out the CT200U-EX playlist. th-cam.com/video/bXRQfwHEPfg/w-d-xo.html
hi, I also fitted the same kit, when I walk 2 km I touch the belt and it overheats why?? yours is the same i.e. does it overheat??? or is it normal??
Arizona
Did you have to use the 5/8 adapter key? Or did the converter have it built in?
After just installing it, it appears to be built in
Do you have to use the key for the 5/8 adapter key? Or does the converter have built in key?
Either way. Depending on if you use a Juggernaut driver or a series 30, driver.
Im curious to see the differences when doing a serious hill climb im debating whether to get a cvt torque coverter or just a bigger rear sprocket like a 72 tooth
I think a torque converter would be better for a serious hill climb because the low range and high range ratio changes as RPM increases. Also, Hills would be hard on a clutch.
@@Black66 so a torque converter and a 60 tooth rear sprocket? Heh heh sounds like a plan. I use my bike for scouting and hunting in pretty serious terrain
Sounded like it kept it in the lower rpm range which will last longer as well
Maybe... I have many different set ups with this bike. Check out the CT200U-ex playlist. th-cam.com/video/X0SmAZJ6qW8/w-d-xo.html
I just installed mine took it out for a test drive. It sheared the bolt Pulley came out flying and hit my leg haha shit hurt. Ganna get a stronger bolt
Kind of new to this, but you mentioned several times about the clutch sprocket, switching from 40 to 35, and then mentioned something about the drive sprocket being 40 or 50T.... ummm isn't the #35 like the pitch and such, and wouldn't you need to chain the chain and rear sprocket to those specs? Or will they work together? Like #35 or 420 or 428? I just thought it all had to be the same "not the number of teeth" obviously.
We do many gear ratio changes in the Coleman CT200U-EX playlist.
What bolt did you use as the retaining bolt for the crankshaft? My torque converter didn't come with one that works.
It's an M6 bolt. You can grab one at the hardware store.
@@Black66 Thanks!
I was looking at the adapters on Amazon and some people are saying they won’t work because the drivers for the torque converter already have a key made into them. Maybe they had different torque converters? I thought all the cheaper ones would be the same.
I have used both with no problems.
That's crazy. I tried to change my shaft to a 1 bore using the adapter 3/4 - 1 inch adapter and I couldn't get it to work out
I have never tried the 3/4 to 1-inch adapter. Only the 5/8 to 3/4, or technically the 16MM to 3/4 adapter.
Hey I’m new to mIni bikes I just installed a torque converter on a stock 212 predator and I feel like I gained no speed at all I’m using a 10t and the stock 50t on Coleman ct200u EX with the stock chain can h give me any advice pls
Where did you get your muffler
Do you by chance know what bolt size I need to go into the shaft on a predator 212 with doing a torture converter?
Yes, here is the link www.amazon.com/30-Torque-Converter-Mounting-Bolts/dp/B0842DML4G
What did you use for extra chain u bought another one or extra from sprocket
You can buy different lengths from sellers on ebay . I use a chain breaker to splice it together.
try putting a juggernaut front pulley on there to let the engine rev out more
I have more videos coming with the Juggernaut, Check out this video th-cam.com/video/Y5KnO0SKWGM/w-d-xo.html
Where did you get the lifter for the torque converter from?
It is listed in the description
does the riser let the engine still fit in the frame if you still have the gas tank on it
Yes, Check out the playlist for this bike. It has had many different combos. th-cam.com/video/X0SmAZJ6qW8/w-d-xo.html
I've seen a couple of videos of other guys on youtube doing a jackshaft delete, and just running straight chain to clutch. What's the pros and cons of doing so? Will that affect torque?
Yes, it will slow it down as far as quickness but you gain a bunch of top end. Not sure if you have seen my video on this but the bike hits over 60 MPH without the jack shaft and a 212.
@@Black66 Thanks for the relpy. I'll have to check it out. I have a CT-200U, the non-EX version. I'm guessing I should not straight chain it to keep the torque for off-road capabilities, like desert riding. Is this correct?
@@trashoperator9278 Yes, or maybe a torque converter. The bike will run in the 50's with a converter with the right combo and still have good low end torque.
How are they running straight chain without moving the motor way over to the right-side to get the sprockets to align?
@@justinmarney6595 I believe there's a spacer on the jack shaft.
😮Damn! 50mph?👍 What did you do, remove the gov? We modded mine and it tops out at 31mph. Have the torque converter and will be installing it this spring.

@@Black66 Very cool! However, I don't dare remove the gov. A friend of mine was a top notch mechanic and advised not to do it. Said it could eventually damage the engine.
@@GreenMountainGoldTrap It will be fine with the governor removed on a stock internal 196 .
@@Black66 i have a stock 196, I was worried that bypassing the gov would cause issues with the flywheel according to TH-cam experts lol. Im looking into upgrading to the torque converter and mikuni carb. Do you recommend removing the gov ??
@@Proto2011Rail Its always best to upgrade the flywheel if you remove the governor. I cant recommend not changing out the flywheel . With that being said I haven't changed out the flywheel or even cracked the case open to remove the nylon governor wheel in this one.

Hey I was wondering I order the same 5/8 to 3/4 adapter and mine is longer than the urs so now it’s hanging about a inch extra from the 5/8 one
Thats ok. As long as the driver goes on its all good. You can always cut the excess off.

Maybe fire it up and run some emery cloth over the shaft . Sometimes they get some burs and high spots on there from pounding it on.
Could you share what Al has been done to the 196, governor removal, valve lash upgrade to how many lbs, jackshaft gear you switched to and I believe you said the rear gear was a 40.

Next video do a before an after on torque converter red spring with green spring
Ill have to do that video.
@@Black66 I'm curious to see how much top speed it makes and 0-30
I tried the green spring and didn't like it. The belt shifts too soon. 0-30 was much slower. Didn't even bother with a top speed run. I run the yellow spring in the tightest hole.
Did the stock gas tank not work with the carburetor?
Yes, the stock tank will work with the VM22
My headlight bracket broke at the welds while riding, have you ever had that happen??
No, not yet...
It sounds like the RPMs run lower with the torque converter. If that's true, then it probably isn't necessary to upgrade the valve springs to 18lbs. What do you think?
Ya, seems like they are pretty decent .
Curtis. A quick look at a speed calc suggests that with a TC and 40 tooth he was running 3200 RPM at 50 mph. If the bike were left this way there's no need for heavier valve springs.
The 3200 RPM is what most get when they install a TC on a Coleman 200 with a mainly stock engine and gearing.
Some of us have geared our bikes opposite of what you see here for higher RPM. As an example, I geared my bike for 30 mph and under trail riding with a TC and 9/60 sprockets. Yet, with a near stock 196 governed to 5K RPM I top the bike out on the road at 47 mph. With stock Coleman gearing I would lose at least 5 mph because there's more power (HP) at 4500 rpm+ to drive the load than at 3200 rpm.
@@Deucealive75 I have never upgraded valve springs on any of my coleman bikes. I have had them into the 50 MPH range with no internal modifications. They have a decent cam and spring package for a stock engine from the factory. With that being said on MY MB200 I have gained 8 MPH simply by changing out springs. I have a video coming on that. With all this being said.
Just because something adds up on paper doesnt necessarily mean it always works out in real life.
Where did you buy the oil drain extension?
At DIYperformance1 on eBay
Which motor is that? I'm new to this but my next mini I'm putting a torque converter on.

Do any mechanic shops ever work on these for people and do stuff like that or do you just have to know someone?
I think places like Volts minibikes in L.A build stuff like this.
Picked up a ct200uex with a bone stock predator 224 max performance motor. Stock gearing and jack shaft. Removed throttle stop screw and zip tied governor. 29 mph top speed. Auto lite plug and .34 jet it ran very strong and accelerated fast. Added a pipe intake and filter and .38 jet. It killed acceleration. Now running .34 jet with a stock filter and airbox pipe and auto lite plug and it rips with no pop on decel. Clueless why this engine doesn’t like mods. Would like more top speed.

Does this bike have the governor removed or just stage 1 ?

By any chance did you have to shorten the throttle cable as mine is getting stuck
Check out the playlist on this bike. We have done all kinds of mods to it. th-cam.com/video/X0SmAZJ6qW8/w-d-xo.html
Yes sir I've been following you for a few months now !! I started my build same as yours but I noticed after I put the mikuni carburetor on the throttle seems to jam up so I was wondering if it's best to trim it and re install the cable into the carburetor???
@@christopherburnssr1660 It shouldnt jam up even with the factory cable. If you cut the cable end about 2 1/4 sticking out and then solder an end on it . It should work .
Just bought one for my son .think it only goes about 20 mph
Ya, that's about what ours did. You can see us throw mods on it on the CT200U-EX playlist. Got it to over 60MPH ! If you haven't checked it out already.
Did the spacers come with the torque conversion kit?
Yes they do . The kit should have everything you need to get it running minus the riser mount . You can add an extra washer to align the pulleys better if you want . The extra washer doesn’t come with the kit .
The link to the riser Mount doesn't work anymore, does anyone have a link of something similar?
Riser mount link www.ebay.com/itm/155376939041
Found one, thanks. After watching so many videos, you made this process way easier. I just posted another question, hopefully you can answer it
Could you gain 6 mph just by gearing. Change a couple sprocket’s
Yes! Check out the CT200U-EX playlist. We gained performance with many different combos th-cam.com/video/X0SmAZJ6qW8/w-d-xo.html
What size jet you have on this
I think it was a 155 or 120 in this set up. Check out the playlist for more combos th-cam.com/video/X0SmAZJ6qW8/w-d-xo.html
I Have a stock motor and top speed is 35 mph but gear ratio is 6.25 ? what should my gear ratio be to get top speed
Not sure what type of bike you have or what the drive Sproket clutch sprocket or tire height is but if you drop that ratio down a little it should be faster. For example, if you are running a 12 tooth clutch and a 75 drive sprocket now, and swap the clutch out for a 15 tooth that would get you to a 5 to 1 ratio. Might be a little slower taking off but would get you more top speed.
Without the jackshaft did it go any faster, before any that's Mods.
