Installing a Torque Converter on a 5/8" Coleman BT200X Mini Bike (196cc or 212cc) - Part 1

Link for Adapter: www.amazon.com/gp/product/B07...
Part 1 of a series in which I install a torque converter on a Coleman BT200X mini bike, as well as a Coleman CT200U mini bike - the parts and instructions are interchangeable. This 5/8 torque converter was purchased on eBay for $65 and compares to models released by brands such as GoPowerSports.
This 5/8 torque converter does require an adapter, as linked above. This video has been broken into 2 parts, as I wasn't aware that this adapter was required at the time of filming. Part 2 should be coming out reasonably soon.
This video serves as a 'how to' video for installing a torque converter on a Coleman mini bike. If you have any other mods for this Coleman in mind, let me know!

Good video explains alot more than other videos

[@victorreyes1010]

Awesome videos bro!!!

[@TysTech]

Thank you!

[@wcwretro2]

My family have the Coleman Ct200u and after riding it I had to get one for myself so I had bought the Coleman BT200X same one as yours and now I'm upgraded the parts on it and I can't wait to see how fast it will ride.

How did it go, and what were all the modifications?

If you buy the right riser from OMG warehouse, you don’t have to cut your frame and loose rigidity in your rear end

[@opusthe2nd]

I've not heard this before. Generally 1" risers. Do you have a pic or video of it without having to cur this bracket?

[@donkeyhole2782]

Nothing worse than losing rigidity in your rear end.

[@dts369]

Your not losing rigidity cutting of a chain guard

[@M70ACARRY]

Please don't cut the bracket. To late! You did.

[@M70ACARRY]

People! You do not have to cut the bracket. Use a riser. It actually does provide structural integrity. Dondo what this guy did.

[@treynavarro7741]

You can cut the screw off on the throttle cable on top by the spring, let’s you get full throttle adds like 5mph

[@outdoorstv7298]

I just ordered one for my Coleman ct200u

[@bubbyhardy6135]

Maybe instead of lifting the entire engine when that bolt almost made the hole you could take a good round or half moon file and file enough to get the bolt in? Maybe it wont work but worth a shot i would think

[@minirider2554]

What size washers did you guys need to use to shim the converter to align the chain?

[@myroneh9570]

Is you sale your clutch Jack shaft kit you took off your Coleman and what size chain you got I need a 415 jack shaft

[@whatever210]

That’s not a just a heat shield. It directs air flow to the head. The engine is air cooled. You need that.

[@joshramirez8396]

What kind of washers did you use and how many?

[@ilkoderez601]

Genius! Just take the cover off the muffler! Nice!

[@marjuspjeci4097]

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??

[@iq-rexzy6159]

which torque converter should i buy?

[@chrivvian]

Can you send me the link of the torque converter?

[@jaydenrosen9201]

do you have a link i want one but dont want to buy the wrong one

[@johncrosby8185]

Run a 8 tooth sprocket on your driven side of the TAV and a 60 tooth rear sprocket. Will give you a 7.5 : 1 ratio and you will get plenty of torque and top speed of around 45 mph.

[@Gixxer-Mo]

Hey buddy, I have been playing w/ the gearing on my daughters bt200x. You say #8 in the front and #60 in the back? The bike is a pig with stock gearing. Can you give me the science behind your ratio? I am really trying to understand these smaller engines. I am use to street bikes.

[@johncrosby8185]

Mo 13 i just tried several combos and that seems to be the happy medium. Has plenty of wheelie torque and good top speed of about 42 mph. Good enough for me to have fun on trails. My daughter has a Ct200 u that has a 72 tooth rear running straight off the centrifugal clutch and it will hit 45 mph but has less torque than my BT200X. I have a torque convertor and hers has the clutch

[@Gixxer-Mo]

@@johncrosby8185 Sounds about right. Im looking for a solid 35-40 w/torque to push her. Did you remove or bypass the GOV. ?

[@johncrosby8185]

Mo 13 no that is with the governor still. Im afraid to remove it cause she is 10 but the size of your avg 14 year old

[@johncrosby8185]

Too much speed for her age. Lol

[@jimmycooper7248]

Hate to say it but what a hack job!

[@victorreyes1010]

Where's the new videos been at?

[@beco89inc50]

When you say your governor is bypassed do you mean taken out all together or just the throttle screw removed and spring cinched down?

[@thomasmgalt6727]

if u bypass it u risk having the governor plastic gear blow up inside de engine, not worth it, just remove it

[@VR-DroneOp1]

@@thomasmgalt6727 that comes out too

[@cwheinz]

Did you have any issues with the chain alignment? I had to space my torque converter way out from the engine in order to make the chain line up.

[@johncrosby8185]

cwheinz yes had to do the same. Had to bring it out alot to get proper chain alignment

[@minirider2554]

What size washers did you end up using?

[@Hj61S827]

This is the what not to do video. My god.

[@markanthony124]

I could not figure out what I was doing wrong lol I left my spacer out

[@ogs_cookieboy9328]

What size bolt did you get for the crankshaft

[@mike88wt]

Is the gopowersports torque converter higher quality or is it all the same as the 60-80 dollar set ups on Amazon?

[@Keebrev]

Just buy a cheap one off eBay. They work just fine

[@rhettcadenhead9621]

I have the same bike but with just 1 chain to a centrifical clutch and I weigh about 175, 5' 10 and without any modifications just a 212 predator engine and it was going at a steady 49mph

[@danielespinoza7880]

Do I have to add 18 lbs valve springs after installing this torque converter with the throttle screw gone?

[@tito2133]

Yup

[@tmurph247]

I did 22lb springs on mine

[@Deucealive75]

Absolutely not.

You need to use the saw correctly it only takes 1 minute to remove wheel

Exactly dude that’s all I need and he’s a idiot

😂 don't use washers ! Get a riser plate , it will be much more sturdy and safer.

[@MJSuperShooter]

what the heck bike do you have that goes 30 stock? mine gets nowhere near that

[@Cam-fo6rh]

MJSuperShooter no governor

[@markcollins5026]

Man, zip tie the inner governor spring !

[@BigDsHomestead]

I'd be careful with holding it open full throttle like that. It could throw a rod.

[@JeffMusicFL]

I feel like if that bar was strictly there to hold the chain guard it wouldn't go all around to the opposite side of the frame... they could've just made it a simple straight bar on that one side.

[@nalong55]

Or bending it straight down on both sides would work too instead of removing it.

[@Smegma_pirate]

Omb Warehouse sells a riser kit that allows you to add a torque converter without cutting your frame

Hi. would this work on a 79 cc Predator?

[@RockieRoadz]

The shaft on the 79cc if it is 5/8" u could get the adapter to 3/4" but the motor is only 3.5hp so it might not activate the Tq Conv. well enough, you'd likely need to change the Tq Conv springs in front and rear, ones that flex easier, to allow the lower horsepower to activate those springs to expand and properly work. That's my thoughts. But I bet there's a uTube video on the 79cc and if a torque converter works.

[@ethanshellen6701]

I have ct200u-X what size crankshaft do i need?

[@minirider2554]

Newer models are 16mm, which is pretty much 5/8". But I'd still pull the clutch and measure it. Only takes 5 mins.

[@garycrandall1652]

That washer setup makes me cringe. Buy the correct riser

[@johnguess5675]

Washer are not machined so good luck not cracking the block. I used 4 machined spacers then slotted with grinder half the chain guard tube for assembly to fit with tire moved forward. Then notched out plastic cover that only 3 of 4 bolts fit unless you make access for 4th bolt.

[@starsoldier3643]

Throw away the washers and buy 4 1inch spacers.

[@antiricergt]

Where’s part 2?

[@johnguess5675]

Pt 1 ended at the 5/8 to 3/4 adapter . Adapter is made for a slotted clutch for keyway. Cvt has key as part of it and would just spin.

[@bruceschmitz1984]

How did the 3/4 sleeve work on 5/8 shaft damn dummies at Coleman lol

[@johnguess5675]

It probably didnt since the cvt clutch has the key in it. If the cvt had a slot then it could work.

[@user-rp5jc5eb7l]

Do urself a favor and get rid of the 🤣 crazy washer thing going on and make a rubber engine spacer I used old belt line and cut out vibration smooth even with the torque converter 🤠

[@Appalachian_Enduro]

[@johnguess5675]

He never installed the 3/4 cvt torque converter on the 5/8 shaft 😡 title should have been not installing!!

[@eskimo_airgunner2314]

That's not a heat shield. It directs the cooling air past the fins. People miss call that part all the time.

[@Deucealive75]

I laugh every time someone calls it a heat shield. And I know it's not nice but it is clear that he doesn't know what he is doing. He should have watched a few of the many videos on how to install one of these before doing his video. There's even a video on how to do it without raising the engine. The process is the same for this newer bike as the older CT200's.

[@tac836]

I can't get over people calling a cvt clutch system a torque converter.

[@eskimo_airgunner2314]

@@tac836 yep, I don't really like the term either because they are a CVT but they are also a torque converter. Not all forms of torque converters are hydraulic. These CVT do not convert horse power, as that is a measure of linear force, but since torque is a rotational force they are definitely converting that into work. If you use the term constant variable transmission, you lose the non-technical people, so sometimes you have to use their preferred name for things. However the blower housing extension exists to direct air around the head and is incorrectly called a "heat shield" by many because they are idiots.

[@Deucealive75]

@@tac836 These were originally designed and manufactured by Comet. You will not find "CVT" in any of their documentation. But you will see "torque converter". We just use what they call their product.
