- Coleman CT200U EX minibike/header pipe and re-jet.
Installed a header pipe on the Coleman CT200U-EX minibike. Also re-jetted the carburetor to enhance the effects of installing the header pipe. Did some top speed runs to see if it gained any performance after the modifications?

I have more coming with this bike . In the next week or so
Thanks for the tip about the Jet! I put same carburetor and air filter on mine and put a 110 jet on it and it does 40mph with a straight pipe too!
I realize this vid was posted a year ago. Great job, love how you make it quick and to the point. I got the same bike your videos gave helped me a lot
Thank you!
I’ve got the same bike about a month ago. What’s crazy is I’m doin a top speed of 39 at the moment. All I’ve done is remove the throttle limiting screw and I moved the black governor spring to the 2nd to last hole on the governor arm coming out of the motor. I weigh 215 and it’s cruisin. Of course I don’t keep it pegged longer than 5 or 6 seconds. Smooth Runnin machine right now. Using the best speed app in the App Store and I tried it in my car and it’s accurate. Just crazy from those 2 mods alone.
Great videos man! Keep em coming!
Awesome! Ya, some of those bike are fast right out of the box.
what app do you use?
It would be really cool to see how this performs off road! That would be a cool episode!
Thanks!Good idea! I'll have to do that. I have a lot more stuff coming out with this bike.
@@Black66 looking forward to it! I’d like to see the low end performance of the centrifugal clutch off-road
That lil bikes bad ass man. Gotta get me one lol. Awesome video…👍👍👍
Thanks! Ya, it is a nice bike
I love the bike! So fun to ride.
Ya, it's a super nice bike. I rode it 15 miles today! lol
I'm gonna have to come check it out.
Love the vids bro
Thanks!!
They make an aftermarket adjustable jet for Honda/Predator Carbs. Might not make the top end of a Mikuni, but is nice for quick adjustments for changing conditions.
I like what black 66 does
Looking better n better!!!👀
Thanks! Ya, it's getting better. We have more stuff to do to it. So it should get even faster.
Well I been watching and learning alot from you! Thanks for ur vids!!
@@keithcola9104 Thanks!! I learn a lot as we go along myself.
What a great idea! The stock exhaust is so ugly especially after the torture converter install. Looking into thia now
Is there an alternative bike with similar specs and frame etc? I've been looking for one for several months.
I can't buy this in Europe/Germany over the normal sites because they don't offer international shipping and I can't find it on Ebay or Amazon etc...
I'm a total noob and not sure what 110 jet to get. Do you have any recommendations? Great videos by the way. You're inspiring me to get more hands on!
Thanks !You can get jets for a VM22 on eBay . Just put in VM22 Mikuni jet kit. You can get an assortment . Or at the part houses web sites .
i have a 208cc motor and i installed the mikuni with a torque converter and she gugles and spits at me at full throttle and she doesn't go over 30 with everything you have on yours and i put 22lb spring in it too but i don't know if need to jet down to a 115
I've seen pavement tires 20x7x8 on eBay, the smoother ride and 1" added to circumstance should make it a little faster and smoother, especially since you only drive on paved streets.
I have been meaning to put street tires on one of these big bikes. I have tried so many different combos on it I figured sooner or later I would get around to installing street tires. Check out the playlist for this bike. th-cam.com/video/X0SmAZJ6qW8/w-d-xo.html
👍
Can u do a detailed video for that bike on installing arc billit rods piston flywheel with 265 cam?
I would like to do a video on this. I will sooner or later.
I got a CT200U -EX as well, I bought it with a straight pipe, no intake, spark plug was changed, that's about it according to the guy. It shoots 2-3 inch blue flames from the exhaust and backfires as loud as a car... Not sure what to do next.
I have had mine for 3 days did some easy mods on it but need more speed!!!
Can never have enough speed!
Hey I have a stock version of this bike. Would adding a pipe negatively effect the motor?
Man they must really have the air flow cut back on the stock exhaust. 5 mph is a lot of gain. ✌
Ya, it really is restrictive
Hey I bought the mikuni tc racing carb and just ordered a jet kit but the jets are different on mine it looks like a tube please tell me what kit to get
Hi I'm thinking about getting one of these bikes, my buddy had one and it was a tank and super fun so I'm finally going to go get one. Can I run a header pipe like yours with the stock carb jetting? Or would I need to rejet
Great bike! I bet you will really like it. You can run a header with the stock jetting and carburetor. If you want to maximize the gains from the header then you could jet the carb.
@@Black66 okay thank you
Hello what total modifications do you have on your mini bike? Did you upgrade the torque converter
Check out the playlist for this bike. It has had multiple combinations.Always trying something new. th-cam.com/video/X0SmAZJ6qW8/w-d-xo.html
Nice video! Won’t you get valve float at high speeds like 40mph? I just got this bike yesterday. I cut the screw that limits the throttle and got 24mph.
Thanks! No, I have had good luck with the stock valve springs on the 196. Check out the CT200U-EX playlist for more combos on this bike. th-cam.com/video/X0SmAZJ6qW8/w-d-xo.html
@@Black66 great, thanks!
Are you on IG? I have 4 of these mini bikes now and your channel has helped me a lot thanks man!
Thanks!That is cool you have 4 of them. They are nice bikes! Ya I'm on there . Its doubledown555black66
@@Black66 sweet. Just gave you a follow. Keep up the good work. I’m gonna order the mikuni carb but been waiting for the Japan one to be back in stock but i may just try the China one because I’m getting impatient lol. Your authentic?
@@toolcartel4213 Ya, mines the cheap one . I got used to working with those lol . And I'm cheap lol . I have a video coming out next week on a real mikuni that I put on the kart. I'm just getting used to tuning that one.
@@Black66 right on! In for results, you should slap it on this and to a top speed to see if it worth the extra moneys
@@toolcartel4213 Good point! I'll have to try that.
Hey man do u think I’d be fine removing the governor? I really like the looks of the VM22 carb will that make it any better?
Check out the CT200U-EX playlist. It shows all the combos so far on this bike. The engine has held up so far. th-cam.com/video/X0SmAZJ6qW8/w-d-xo.html
@@Black66 I have the ct200u not the ex
Did you have a torque converter on or just regular clutch?
The stock jack shaft is on the bike
@Black66
I'm having trouble getting my mini bike get to the same speed as yours. At most, I'm touching 36mph. I have to exact same mods your bike has at that moment. the only differences I see is my header pipe is the one that goes underneath the seat and out on the right side of the bike. And i have the crankcase breather filter on mine. Any tips please
There are so many variables. Rider weight , elevation etc,its hard to compare one bike from another Check out the CT200U-EX playlist. There are many part combos one there to get you to the speed you want to be at.
I love that header pipe , I one we got sticks out and burned my leg , do you have a link for that pipe ? Thanks in advance
Yes, the link to the parts is in the description of the video. Thanks for watching the videos. Check out the CT200U-EX playlist for more combos with this bike. th-cam.com/video/X0SmAZJ6qW8/w-d-xo.html
Can you tell me where you get your parts. I just got the same bike and want to get it to 45. Also did you just pull the screw to remove the governor or did you go into the motor and pull the white plastic gear?
I get a lot of Parts from GoPowerSports . Check out the CT200U-EX playlist. This bike has had many different combos on it. Here is the link th-cam.com/video/X0SmAZJ6qW8/w-d-xo.html
I’d like to see another desert ride vid!
I would love to do one. That Route 66 video was fun !
What size jet are you running? I put on a new carb with a .038 and it wouldn't stay running when I switched to run so I adjusted the idle and got it to stay running but when I rode it it bogged down so I went back to the stock carb and it runs a bit better but it lags when I rip on the throttle.
In this video, it was running a 110 main jet. And the slide was set on the center slot. It ran really well with this combo.
@@Black66 Thank you!
Did a carb swap and my bike is back firing after letting down on gas
what app do you use to see have fast you go?
I'm using digiHUD on my phone and the camera GPS for top speed and a Dragy performance meter for 0 to 30
Which carb do i buy cause there are 2 in desc and also will this exhaust pipe with silencer work on bt200x bike
The second carb in the description will fit your bike. Here is a link for a pipe for the bt200x . www.gopowersports.com/header-pipe-muffler-economy-coleman-200/
Do you have to reject with a header pipe and muffler?…………edit, found me answer in the comments
I put just a straight pipe on my bike. I’m pretty short so I’m always burning my leg even with a heat wrap. Do you think that pipe would work better?
The short pipe works pretty decent on the Coleman bike. If it stops you from burning your leg its worth the swap.
@@Black66 any suggestions on a shorter pipe?
@@tracyazevedo The link is in the description for the pipe and silencer I used in the video. I saw a few more short pipes besides this one from sellers on ebay and the minibike and kart part stores like Go power sports, BMI karts, Studz racing , OMB warehouse.
Are you planning on 212 swapping the bike or are you leaving the 196cc on it?
We kinda keep going back and forth on that. We might modify the 196cc more and then, later on, do a Predator swap. In the meantime, we can modify a Preator on the bench so we can just put it on already done.
@@Black66 I think you should avoid the 212 swap and keep building on the 196.
@@Deucealive75 I think your right. I would like to see what we could get out of the 196cc.
@@Black66 if you do a cam I would highly suggest the Dynocams CM x cam. I built two with the CS cam and they are great but only to 7k. I have the cs cam in "Black Betty" on that Hisun 196 right now and really wish I did the cm.
@@fatbuddycat Thanks! We're gonna end up building it sooner or later. I'm not sure what the specs are on the CM x cam but I'm already using the 265 "Superman" series cam in a 212 and I love that cam. It has so much torque through the rpm range.
Just got one need to know if u can get that header pipe or need custom made.
Ya, you can buy the header already bent to fit . Check out the other videos . I’m pretty sure I added the link to the pipe in some of the videos . If you can’t find it I’ll get you the link
i did mikuni carb swap and i cant get it to run more than 2 seconds and it wants to drive of for them 2 seconds. im baffled
Make sure you have the carb bolted to the manifold correctly? If you have the carb off the bike you can look down the manifold to make sure its in alignment . If the o ring is leaking between the carb and manifold, it wont run right. That's one of the most common reason they don't run right when first installed. leaks
Dang thats pretty FasT!!!!!!!!!!!
It gets faster ...
If u can manage to find one. Try adding a 40 tooth sprocket to the rear. It might be hard to find but trust me you won't be disappointed. It made mines do 43mph without mods. So yours should be 45-50
That is funny you mention that. 40 sprocket is our next video.
And then we have a couple of videos after that , so far.
So if I do stage 1/Cut governor screw/40 rear sprocket/zip tie mod how many mph should i get?
@@l.a.m7645 40 give or take depending on the weight of the rider and the elevation the bike is being run in. It's hard to nail down an exact speed. But it will definitely be a lot faster than stock.
@@Black66 how do u do the zip tie ?
@@Thelegendking-yj4bm Run a zip tie through the spring on the governor arm.
I'm doing just fine with my 32 miles an hour with the factory engine 196cc just learn how to tighten up your spring to the governor and carburetor the right way where it's not over idling and pulling forward when you start it that is the threshold point of this engine before over revs will happen.
We didn't think 40 MPH was good enough. We wanted to go over 60 MPH Check out this video
th-cam.com/video/jHf9yJmaZLA/w-d-xo.html
I just did the same with my baja 196. Bought a bunch of springs & put the mini on box to free the back tire. After quite a few tries I found a tighter than stock gov spring & placed it in the center hole of the arm ...BINGO 30 MPH! Getting "float" at top speed Yours the same??
@@dunamon Check out the playlist. No float with these mods th-cam.com/video/X0SmAZJ6qW8/w-d-xo.html
Where did you get your jet kit from
I picked these up from a seller on ebay.
I think GoPowerSports might have them too.
Do you have a link to where you got that carb ?
Yes, I just added the link in the description.
Can u send me a link for the muffler clamp around the exhaust
www.gopowersports.com/rlv-muffler-clamp/
I just change the jet to the same one you put didn't pick up any speed reason why
My jetting will not be the same as your jetting. No one's jetting will be the same because of different altitudes, different engine mods, etc. I live at 3700-foot level. I tend to get away with a smaller jet than a person let's say down at 700-foot level. There is no one size fits all jet.
Thanks for watching the videos!
Another question when I change the carb and reset to .038 do I need a better spark plug? If so what one
No, the one that it came with should be fine. There are really good after-market plugs but the stock ones work well.
Would replace thumb throttle
With that muffler directly towards the tire wouldn't that burn a hole in it?
No, it’s not close enough. We have a lot of hours on this bike now .
@@Black66 nice
@@Black66 hey the exhaust itself I'm planning on getting but do you think the silencer is needed or is it only to keep the bike silent like if I where to not get the silencer would it still work just fine it may sound like a dumb question but it's always better to ask you know
@@theoutdoorsgamer5564 ya, it will work fine without the silencer .
@@Black66 great
Should retrofit that gas tank inside the fake plastic gas tank Then again Im assuming the fake plastic tank is a glove department and thats nice to have as well and the gas tank doesnt need to go there.. but would just look cool.
I have a video coming out. We did exactly what you said. It doesn't have the gas tank on the engine anymore.
Do you have a link where I can get the jet?
Yes, I put the Jet kit link in the description of the video. Thanks for watching the videos!
I want to achieve 45 mph. Any thoughts? Just street legal. 45mph is fine.
Not sure if you looked at the playlist for this bike. if you haven't, check it out. It shows how we got the bike going pretty fast th-cam.com/video/X0SmAZJ6qW8/w-d-xo.html
@@Black66 I did. Thanks. Helps a bunch. 👍👍👍
Have you done valve springs yet?
No, we havent done anything internal to the engine yet.
Let's do it!!!
@@eyehearther111 Ya, we need to see what we can get out of the 196cc engine .
I'm running 18lb in my predators... Wish i would have went 22, start floating at 4000rpm
@@coreybarrick3146 I hear ya. When I put the 1.2 ratio rockers on the minibike I had to upgrade the springs from the 22lb springs to 26lb because of valve float. It was easy enough though because I filled the combustion chamber with string so I didn't have to pull the head back off. I did it on the bike.
According to my calculations, going from .120 to .110 is a 16% difference in jet size.
Significant in power and fuel consumption.
Yep, I think a lot of people forget about altitude. If a certain jet size is good for me at 3500 feet, that doesn't necessarily mean its good for you, let's say at 1500 feet
I found this out when I drove to Havasu and my bike ran like crap LOL. 3100-foot difference in elevation
@@Black66 if I put a header pipe and a air filter would I have to do another jet and i bypassed the governor
@@markrice6782 You don’t have to . It would probably still pick up some performance without jetting . But if you do jet it , it will optimize the combo.
If you already jetted it . It will definitely gain some performance.
Where did you get that header pipe for the CT 200 UEX
WE have a couple of different pipes for it. the short one is here www.ebay.com/itm/273555452026?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649

Do you have to rejet the carb?
It comes with a small jet. It will run out of the box, but it will run a lot better if you re-jet the carb with a bigger jat.
