love these videos man binged watch them all morning and convinced me to spend a little more on my mini bike, will be well worth keep it up man💯
Thank you! Thanks for watching. I hope the videos help you. I'll try and keep the videos going .
I’m waiting on parts now for one bike and parts in the eBay cart for another
I love your videos man! I have a 212 predator and a torque converter in my coleman ct200u-ex, all stock and man that thing is a blast!
how fast
is it
I Enjoy Your Comparison Videos. And Keep The Videos Coming
Thanks! I have a lot more coming
Your content stay the same it's cool keep it up
Thanks for this video, Iam restoring a vintage 1990s Dodge Viper go cart , right now it has an older Honda GX100 engine in it which is pretty anemic for such a cool cart,i plan on replacing the tired engine with a brand new 208cc electric start and using a long exhaust off amazon, according to my measurements it should come out right near the center of the rear bumper to replicate what the real full size Vipers had, another option I wanted to do was to make a custom dual side exit exhaust, but if i went that route ill have to brush up on my welding (I have shaky hands) because i want it to look pretty for such a unique go cart.
Sounds like a fun project .
Sweet test! Hilarious when that pipe fell off😄😄😄
Good ideal thanks
Thanks for the info
I have a 1 inch pipe right now and she gets up and goes immediately.
Can you do aluminum vs cast iron (but not a tilly) flywheel comparison in the 0-30? My bike sure felt snappier with the lighter flywheel.
Ya, got ya covered. You guys must read my mind
Speeds are about the same. I did GoPowerSports billet flywheel, billet connecting rod, "cruiser" cam, 22mm Mikuni carb long exhaust pipe with a 30 series torque converter. Stock gearing, 43mph. Punchy off the line. I am 200lbs to give you an idea of weight to the bike. I have the same CT200U EX bike as shown in the video. 196cc engine.
I ordered the staged header u recommended!
That staged pipe is a good one!
In the car world, they always say longer intake runners improve torque, as do longer exhaust header tubes. Shorter ones improve top end hp. But does that apply on a 1 cylinder, 8 hp engine? Beats me!
I have videos coming on this topic
What did you use for a gas tank inside the compartment? I like that. My gas tank rattles so loud
Check out the CT200U-EX playlist. The gas tank video is in the playlist. ua-cam.com/video/X0SmAZJ6qW8/v-deo.html
Man your the expert I’m having a issue with my chain popping off new chain new master link but my cc100x pred swap doesn’t have a chain guard it has the ball thing or tensioner whatever it is. My question is will a chain guard help keep my chain on?? I don’t want to go down the road and the chain pop off and lock up.
No the guard won’t help it stay on . Is it tensioned properly and is it in alignment?
Make sure your sprockets are lined up in a perfect straight line, also check for any bends in the sprockets, missing or worn teeth.
44mph? Has torque converter upgraded? Or factory jockey clutch?

dope
I installed the straight exhaust pipe, added 18# valve springs and zip tied the governor spring. I get up to about 39 mph now but when i let off the throttle it starts popping out of the exhaust! You think i need to lean out the jet? Maybe go down to a . 039 jet?
The popping has nothing to do with the main jet. When you close the throttle at high RPM it's not getting enough fuel and a lean condition is created.
Great content 👍🏿
Thank you!
Question I zip tied my gov spring and I’m putting in 18 lb springs will I still have to worry about floating the valves? Or the governor exploding inside the engine?
No, i wouldn't worry about it. It should be fine. Anything can come apart but
These engines are more durable than a lot of people think.
I have ran this engine for getting close to a year now without even opening the case . We have did all kinds of external mods to it . Check out the playlist on this bike .
@@Black66 ya I’ve watched a few of you videos very informative I appreciate it. Like I said valve springs are on the way along with a new carb. Thanks for responding
Nice modified Would you modified the same bike for a fan?
I have the cc100x with 212 pred I’m thinking of getting another mini what do you think is the ultimate cruiser
That is a hard question. I'm not sure about the ultimate cruiser. I guess it depends if you're talking big or small bike. I can tell you the smoothest riding mini I have ever ridden is the MB200
@@Black66 yes the mb200 at mid range feels very smooth
I have a predator 212 hemi with a long pipe and stock carb and Jet will it hurt anything
The long pipe isn’t up anymore do u possibly have another site to buy one I’d really appreciate it so much
Great video as always! One question. On you’re ct200u (red) have you done anything inside the engine like any billet parts? I’m upgrading mine soon but I don’t feel like installing all the billet parts, if I’m not full speed all the time i should be ok right?
Thanks! No, I haven't installed any billet parts in the 196cc. It seems pretty durable so far.
@@Black66 what parts do you have on it right now, and you hit 40 on it correct?
@@Shane.Snowhill Check out the last video in this playlist ua-cam.com/video/ZFLSbnoH59g/v-deo.html
@@Black66 alright thanks, the parts you listed in the beginning is all the parts you have installed correct?
@@Shane.Snowhill Ya, that's it so far on that bike
What is plastic tube sticking out for?
That is a vent tube for the gas tank. I installed a gas tank in the cargo compartment. Here is the video link ua-cam.com/video/j7U_0GgGLng/v-deo.html
Great test. Do you know fo any staged headers that fit the ct200 u-ex?
Thanks! I haven't seen one. Though about making one...
What’s the highest rpm the stock rod can handle on the Coleman 200?
Love your channel it's very interesting I would love to see what the coleman bike would do with 18 pound valve springs vs stock 16lb. Regards keep it up!
Have you tried running a reverse cone megaphone (sp?) on your straight pipes? There is some exhaust pulse tuning benefit to those. I don't know if you could buy one or if you would have to fabricate one. I have seen plans on the web to build from flat sheet steel. Cut, roll, & weld. (I know you weld) I used to run one on my Honda SL100 back in junior high. (1971-72) Mine had no baffle - just straight tuned megaphone. It was loud, but that little bike was pretty fast with it on.
I know what your talking about. I used to have one on my car back in the day. I have did test on the exhaust Trumpet.
On the ct 200u ex ,,, 45mph what kind of drive train did you have on it? That was with the long pipe. I have the 196cc.. please advise.

Hey man i know im late
But ive got a question
But first a little substance for my question
Ive lived my entire life so far in houston county ga.
(42 years) never done much travelling but want to see the nevada desert
Planning a mini bike desert road trip
So my question is would i do better to mod the engines for performance
The exhaust im thinking maybe stock because
It seems to be the quietest any info/ input you have would be greatly appreciated and considered
A stock engine would work for cruising the desert . Adding a billet flywheel and rod will add another level of safety and support performance mods. . While your in there might as well add a 265 cam with some valve springs to add some performance.
@@Black66 i will certainly look into the performance mods my main concern though is the muffler
My fiance and i are gonna be putting quite a few miles on these things and were mainly concerned with the noise levels
Check my channel out ive got diy and gun videos
I want the longtube header but the link no longer works do u have another link ?
You can find it on the GoPowerSports web site . Coleman CT200U-EX exhaust
Are you still using the same jackshaft ir came with it or a torque converter?
This bike has had many engines and combos. Check out the CT200U-EX playlist ua-cam.com/video/X0SmAZJ6qW8/v-deo.html
I installed a long pipe on my stock bt200x. Now it just overheats and dies out in about 5 to ten minutes. Could be im a noob and hardly service it other than the oil changes, spark plug cleaning, and bold tightenings. Maybe a carb cleaning is in order?
Did you also add a bigger jet and air filter adapter? Might be running too lean.
@danielaltamirano322 no ill have to do that. Youre definitely right.
@Whoop!!
Did you relocate the headlight it seems higher
Where did you buy your long header pipe from ?
Do you have a link for it where you purchase it from?
I put the link in the description
Why didn't you have the tachometer in the corner for the long pipe testing as you did for the short pipe. It's almost like it was a biased opinion to which pipe YOU like better.
The channel is about testing this stuff. I have no bias on how things turn out. Just trying to figure out what works best on any given combo. Sometimes there is a glitch in the GPS software where it won't read correctly. Check out the playlist for more combos ua-cam.com/video/X0SmAZJ6qW8/v-deo.html
Hey I put the long pipe on my ct200ex and now I don't have acceleration and idea why?
Need to re- jet for the pipe
@@Black66 can you re jet if you have the stock carb and air filter
@@ryanilano2869 Yes but usually you need an easy out to get the main jet out of a Coleman carb. They are EPA carbs. Also I would add a high flow air filter to go along with the re-jet and header pipe. Short answer, yes you can re-jet a stock carb.
@@Black66 thanks I ordered an aftermarket carb and intake as well just hasn't came in yet
just for kicks try that test without the muffler
Can you build my 200u-ex to go faster ?
What do you want done to it?
@@Black66 governor remover in to adjust my throttle cable! i have the stage 2 kiton it still not fast enough only 27 mph Max!!
@@bigpoppachino3437 It should be faster than 27 mph
@@Black66 i just dont know enough about them like you do definitely need assistance
Where did u get the muffeler for the short exhaust?
Studz Racing
Whats the name of the gps app?
What type of oil do u use on your mild build s on cc100x
I use synthetic 10w-30 for this stuff. Not to brand-specific. No failures yet...
What App are you using for the MPH
I use DIGhud on my phone , the camera GPS for the speedometer and a Dragy performance meter for zero to thirty.
That way I get the speeds pretty accurate .
So what your saying is short pipe cause it looks better
Who cares if it runs good, as long as it looks good that's what its all about.
@@Black66 damn right
So wich do u reccomend long or short?
I like the long one .
Is this with centrifugal clutch or torque converter?
It’ has a jack shaft in this video
@@Black66 : Oh, I see it now on your other video where you changed the rear sprocket. It has a centrifugal clutch driving a jackshaft. Your videos are fun to watch. Thanks!
@@donkeyhole2782 The jack shaft has a centrifugal clutch .
@@donkeyhole2782 Thanks !
Long songs better and looks better

And y
That thing sounds stout is it a jang dong
five point fiy fiy lol
I will never understand why
Speed, a straight pipe is like running and breathing normally or even with a oxygen can and a stock is like breathing through a straw it’s doable but you’ll struggle after a while
@@MichaelPortillo-cw4ktthat's the best explanation I've ever heard lol
@@CarlTheColeman 😁🤭
I would like to get the short one but my bike is completely stock everything, I haven't even done the throttle screw mod. Do I have to do any adjustments first or can I just switch out the original muffler for this one?
Yes you can.
