- This is a how to video with step by step instructions on how to convert a Baja Warrior or Mini Baja to a torque converter clutch for more torque and more speed.
In the video I show all the steps then take it on a top speed run to see the difference.
It is a Comet TAV2 30 Torque-A-Verter for a 3/4 inch shaft and the 10 tooth sprocket for a #40/41/420 chain.
I hate hearing my own voice so I lowered the pitch of my narration a bit so it sounds like someone else lol. :P
great video . i am working on basically the same bike for a customer and what i think was missing was the spacer for the shaft and the first plate which was rubbing against the bolts on the block.
ya, it makes it feel like a whole new bike. Best upgrade for these bikes IMO.
Could you tell me if an "impulse" type fuel pump would help the performance of a clone engine? Also, is there very much difference between the 196cc and the Predator 212cc engines? Thank you, any input would be helpful and appreciated.
Sorry don't really know enough about small engines to know if that fuel pump would make much difference. As for 196cc vs 212cc, I haven never tried one of the predator engines but I really can't see 16cc making much of a difference.. Perhaps someone that has tried both could better inform you though.
"But its the one you have is the best you have?" hmm not quite sure what your asking. :P Ya if you've never rode before I'd keep it stock until your completely used to it, then from there I would bypass the governor to give you more speed and get used to that. Then once you get board of that go with the torque converter for even more power and speed.
someday i will make one for my kids...i have one convertion
Thanks! :D I would say the TAV is definitely worth the money. Makes a huge difference! Its almost like putting an engine twice the size on it because now the engine can make full use of its HP at any speed.
@SuperConfederateMan Thanks! :D Apparently there's one gokartsusa sells, that was mentioned a couple comments down, that mounts right up with no mods needed. I've never used one of those ones before so I don't know anything about it, but it might be something to look into.
take off the engine.because that will interfere with the torque converter lol.
Too busy with school and stuff right now to make new videos, but you can get cheap key switches that you would cut the wire from the stock switch and then attach that wire to one end of the key switch then the other end of the key switch to a ground and now it won't start unless there's a key in the key switch and its in on position. Although this wouldn't be good for anti theft if that's what your trying to prevent because then they could just disconnect the ground and it would start. :P
Centrifugal clutches slip a lot easier and burn them selves out quicker then a torque converter would for off roading.. I don't think there's a single advantage to a centrifugal clutch over a torque converter clutch. If you were to get yourself in a situation where your burning belts you would also be burning and wearing out a centrifugal clutch in the same situation, the difference being a belt costs like $20 to replace whereas a cheap centrifugal clutch would be like $50.
I had this same minibike years ago and the factory jack shaft is junk... I ended up flipping the clutch 180 and running the chain direct. it was slow off the line but it went at least 70mph
bullshit it wont go 70
Wow excellent job and well documented thumbs up I wish they still had the star rating s because this is a 6 star forget about the old 5 stars awesome job very impressed
Translate says "A good chain replaced the rubber crap? Why?" So I'm guess it means why replace the chain with rubber? If so, because the chain and clutch is single speed, the torque converter is variable speed, so more power + more speed. Also the centrifugal clutch the chain is connected to slips way easier then the torque converter does when it comes to climbing.
hmm its probably either the driver and driven pully aren't lined up correctly, your trying to climb steep hills from a stand still causing the belt to slip and burn, or the belt inst on properly? Most likely misaligned, the back plate of both the driver and driven pully should be perfectly aligned, one shouldn't be more forward or back then the other. Give that a check.
@thatcrazycat11168 hmm not sure, perhaps the belt is just too burned up and not gripping right, or somethings wrong with the weights or spring in the driver or driven or maybe the moving parts need to be oiled up. (if you do oil up the moving parts though, make sure you don't get any anywhere the belt makes contact with)
ya I'd definitely say get the torque converter, it's not that hard to put on and you'll be getting a nice upgrade and something a more reliable then the stock gear reduction kit. I don't think you'll find one in a junk yard though. I'd try gokartsusa or ebay.
I used to get them right from the comet site but you can't seem to do that anymore, so try ebay or a lot of people seem to get them from gokartsusa. You just have to make sure it can handle 6.5hp, is for a 3/4inch shaft, and is for a #40, #41, or #420 chain size.
Sorry, I have no idea what the exact bolt size is, you could probably find out with a little googling though. :P I would definitely not ride without the bolt, your clutch could come flying off and cause some serious damage.
no idea. :P if it broke off you may have to get a new unit, or Macgyver something, or just remove the whole unit and connect the 2 chains, that would gain you lots of speed but you would loose lots of torque. :P
@KiidJerkk323 can't remember, sorry. :P Did it a long time ago and Bikes at home and I am away for school so I can't check. :P I'm sure you could probably find the size online somewhere if you do a search for it.
Or just buy the Trailmaster MB200 which comes with a torque converter stock and has front and rear suspension so it rides way better than the Baja. It's also about 4" longer so it's a slightly bigger bike overall.
The video is 10 years old
I'm not sure. I've never bought one from there. If its the actual Comet TAV2 30 then you probably will, but if its one of the clones or knock off brands you might not, but I don't know for sure.
No, should be fine. As long as you not stuck somewhere and just keep holding the gas and the tires aren't even spinning. :P A torque converter is a lot better then a centrifugal clutch for off roading.
@thatcrazycat11168 Sorry, I wish I could tell you but I can't remember off hand. I would just start small and keep trying different sizes or combinations of sizes until you find the perfect fit.
again, not too sure what you are talking about? :P If its too slow put on a torque converter, bypass or remove the governor, or get rid of the jack-shaft for maximum top end speed. :P
@soulevs Regular price on the bike here is $699, not sure what they go for in the states though. Then the torque converter is about another $200. I like it, it's fun. :)
again, don't know off hand. I have a ton of bolts so I just keep trying different sizes until I find the match, but have no idea what size that match is. :P
Don't know off hand. I have a ton of bolts so I just keep trying different sizes until I find the match, but have no idea what size that match is. :P
My mini bike goes just as fast with a predator 212cc with the governor bypassed.
video legal
only if its for a #40/41 chain. But chances are the 12 tooth is for a #35 chain which wont work with this bike.
hmm I'm not too sure what the problem is. I would probably have to see a picture or video or something..
I would think they would come with it because that kit is supposed to have everything you need in it.
I'm pretty sure that this is "leafy is here" (TH-cam channel) but he secretly works on bikes
Pls were can I get a racing clutch to buy
Pls. Send me ur contact number
but greasy is more manly! lol. Also I don't think the dirt is covering up any important details?
I would think it would unless baja decided to move something slightly between the 2 bikes. :P
interesting.. well I'll let you know if they ever explode on me lol. Ya if you have a go-kart you might as well get it going! I actually find 4 wheeled toys a lot funner then 2 wheeled ones, because you can be a lot more crazy on them and not have to worry about the wheels slipping out from under you. :P
@TheTonganwarrior1 various places. could try ebay or a quick search brings up a place called mfg supply that seems to sell em. do some searchin lol. The last time I bought one I got it right off comet's site but then they got bought out by another company and don't give that option anymore, so I don't know where the best place would be. :P
you might of bought a torque converter for a 1 inch shaft rather then 3/4 inch. Only thing I can think of is exchange it for the smaller version or if you can't do that you may have to buy a new 3/4 inch driver unit, or see if you can find some sort of adapter to go from 3/4 inch to 1 inch.
@XB0XFR34K Probably wouldn't be much slower, just wouldn't accelerate as fast. When the clutch is in its high gear the engine doesn't really have enough power to push much past the governed rpm if everything else is stock on it. My guess would be around 60km/h.
it comes with a go-kart type clutch already on it, and if you wanted to you could remove the jackshaft and join the 2 chains together and run just straight clutch to back sprocket and you will get around 80km/h or more out of it doing that. BUT you would loose all your off-roading capabilities. it takes a while to get going, you wouldn't be able to drive up a steep hill from a stop and driving on rough terrain would probably just fry your clutch.
@islandminisunlimited actually do you know what, I just remembered what I did with it. I put it on my old mini baja that I pulled the torque converter off of, because the one that was originally on that one I cut up and converted to a chain guard when I converted my baja dirt runner 49cc to a 6.5hp mini bike. I want to keep the old mini baja operational so I guess I cant sell the part. :P sorry :(
@thatcrazycat11168 the torque converter I use is the Comet TAV2-30. But ya that sounds pretty good if all you need to do is buy a belt and put the torque converter on and your good to go.
Sorry In order to do that I would have to pull my bike apart to get a good video and I don't really have the time to do that right now. Could you just go to a store that sells them and see how it is hooked up on the display bikes? Thanks! Glad you like my videos. :)
ok cool
that depends. If you keep the jackshaft on it and put a smaller sprocket on the back it definitely will go faster but you will loose bottom end. If you put a torque converter on it, then put a smaller sprocket on the back, in theory it should go faster, but I've tried putting a bigger sprocket on the torque converter itself which in theory would be the same as putting a smaller sprocket on the back and all it did was make me lose bottom end but the top end stayed the same.. so idk. :P
@andrewzb the top end would probably be a bit higher but it would take longer to get there. also you would loose a ton of bottom end and doing rough off roading or climbing would more then likely fry the clutch. The torque converter gives you more bottom end then the gear reduction kit while also giving you close to the same top end as straight chain to back sprocket. Also if you fry a torque converter belt its a lot cheaper to replace then if you were to fry the centrifugal clutch. :P
Sounds good. Have Fun. Just don't keep it wide open for too long, would hate for you to kill the engine before you get a chance to get a torque converter for it, lol. NP, take care. :D
Definitely! The difference feel like you put on an engine twice the size. :D
It would be like locking your car or dirt bike in 5th gear and driving around like that, whereas torque converter gives you gears 1-3 and is constantly changing between them to give you best performance. Torque converter gives you, decent speed (70km/h) and lots of bottom end torque (can do wheelies and climb).
But when I first added the torque converter to the original bike the governor wasn't bypassed and if I remember correctly, top speed was pretty much the same, it just took longer to get there and didn't launch as hard.
meh I'll take that risk, they work fine. :P Impact sockets cost a fortune and I don't use the impact wrench often enough to want to buy a separate socket set for it.
Its basically like putting an an automatic transmission on the bike, like a car. Much less strain on the engine compared to the stock gear reduction system because now it pretty much chooses the perfect "gear" for what ever situation it's in to make best use of the engines powerband.
Ah I see. There are better more expensive ones with higher ratios, but this one is the easiest one to put on because its all one unit. The bigger ones are 2 separate pieces so you would have to come up with your own mounting system.
@islandminisunlimited ya I probably could. I think I still have it lying around somewhere. :P Although I'm away from home, for school, until like May.
Ya I guess you could just cut the chain guard if you want to keep it. I just didn't care for it much so It was just easier to get rid of it altogether. Glad you got it to work with the original holes though. :D Although I'm not sure if I would want to start bending parts of the bikes frame because it might cause a weak spot. :P But who knows, I guess only time will tell, chances are it will be fine.
@ShityDurPirate like the sprocket things the belt sits in or the sprockets the chain sits on? The back plates of the belt sprockets should line up and same with the chain sprockets or you may get premature wear and not be getting the speed out of it that you could.
The GPS can calculate your speed based on the distance you cover and the time it takes to cover that distance. I've compared the speed the GPS calculates in real time while in my car and it is identical to the speedometer speed so it is accurate.
PLEASE RESPOND ASAP... I have the same bike with the same "old" clutch setup not the torque converter. I recently lost my bolt that holds the clutch in and i really would appreciate if you could tell me the exact specifications on that bolt so i can go buy a new one. Also do you think i can ride it without the bolt in there? This would be a huge help for me if you could answer my questions..
Thanks in advance
@BraneDrane100 it's a Comet TAV2 Torque-A-Verter. I believe they are just saying the shaft of the engine needs to have a screw hole in the middle of it, which it should. I've never seen a TC2 so I don't know for sure, but according to the description on gokarts usa that one just mounts on with no mods needed..
I flipped around my clutch and took out the gear reduction and the governor I could do 70 km/h full out but I over heated my clutch and it locked up so I have to push start it. Ps its for sale $300 obo
I just got one of these and it's throttle and governor assembly is took apart and I have no idea how or where the springs n stuff go, is there any way you could do a good slow film of how all the throttle governor assembly is linked and maybe a diagram in the video?? Would help me a lot! Thanks and I think your videos on "upgrades" are great!
This is a brand new bike, but the one I pulled the converter off of and often use for experiments is a few years old and dirty, yet everything still comes off just as easily. Although I store everything in a dry shed, I guess if someone stores there bike where water can get to it and everything is rusted on, it might be difficult to get apart. As for caked on grease, that can be fixed by just taking a pressure washer to the bike and giving it a good cleaning. :P
No Problem! Hmm, the only thing I can think of is your belt has worn down or is glazed over from continuing to rev the engine when the belt is slipping?
if its the tapped crankshaft then ya, if its the threaded one then not unless you find some way to hold the clutch on. :P
didn't work. think growing an extra foot would be more effective.
Not sure. I think I recall seeing a video of someone putting a torque converter on with that setup and they found some sort of lug nut that fit perfectly and held the clutch on fine.
Thanks. I try to respond to just about everyone except for trolls. :P It definitely climbs better with the torque converter and doesn't slip as easily as the centrifugal clutch does if your starting a steep climb from a stop. It's the middle of winter here so I wouldn't be able to do that for at least a few months.
its 3/4 inch. the difference is the size of the shaft on the motor. yours will likely be 3/4inch. 4-8hp engines are usually a 3/4 inch shafts, less then 4hp is usually a 5/8 inch shaft and more then 8hp is usually a 1 inch shaft.
I have no idea sorry. I just have a pile of bolts and try em all until one fits. :P You may be able to find out if you look up a spec sheet on your engine?
Stock with governor bypassed top speed was 34mph, once torque converter is on and working right top speed is 44mph.
Nah. The top speeds for this are:
Completely stock - 36km/h (22.5mph)
Governor removed/bypassed - 54km/h (33.75mph)
Jack-shaft replaced with torque converter - 70km/h (43.75mph)
However Jackshaft removed, clutch straight to back sprocket - 85km/h (53mph) (lose most bottom end torque though)
động cơ bao nhiêu công suất thế anh,em ở vietnam muốn làm 1 chiếc xe như anh, anh có thể chỉ em cách làm
nah its a sealed slot, its solid a little ways down into it.
@allezsport2010 gives you more bottom end torque and more top end speed. Its like putting an automatic transmission on the bike rather then always being stuck in one gear.
Very nice bike
I got a mini off craigslist and the chain was rusted solid. I took it home, cut the chain off, and installed a new chain and clutch kit from Ebay www.ebay.com/str/sellerwarehouse. It only has a 3HP motor but honestly, I don't think I want more power, the 25-30 MPH seems enough to kill me already. I want some type of kill switch now because I worry I might mess myself up on accident. Maybe I will just sell this one and find another to put a chain and clutch on. Installing the parts was the funnest part and increased the value $200 easy.
Thanks! I've never seen the baja heat model so I have no idea. :P The torque converter comes with everything you need if you get the actual Comet torque converter kit. Not sure about the knockoff kits. If you look on my channel under How to and assembly videos, I have a un-boxing video of a brand new comet torque converter kit that shows you everything that comes with it. :D
I got mine at a Princess Auto. But in the US I think you can get them online at gokarts usa or mfg supply.
Well there's way less vibration with the torque converter compared to the stock centrifugal clutch and it engages a lot smoother, but I have no Idea how it would compare to a racing centrifugal clutch, I've never tried one. :P
NP. Although if you just want speed and don't mind loosing torque, you could always just remove the gear reduction system and attach the two chains together so your going straight from clutch to back sprocket. :P
no problem! It all depends what you plan on doing with the bike. if you were racing it or just cruising around smooth paved streets CC would probably be the way to go but if your off roading and trail riding and that kind of stuff then TC is definitely the way to go. :)
they're around $270 CAD here, but you could probably find them for around $200 in the US.
@LHRShadow lol I wish I did. I guess you could try your luck on ebay or something, or look around for a used one somewhere. :P
I'm just gonna buy a new torque converter.. lol
Comet TAV2-Torq-A-Verter, 3/4" Bore 10 Teeth, #40/41. Around $270 in Canada or $200 in the US. You can also find cheaper knock off versions of it too if you want.
now cut off the long shaft coming out of the engine, because that also interferes with the torque converter... LOL
yea he really went the long way around to do this swap. if anyone else is here for tips, you can simply notch the aluminum backin plate where it hits the frame and likely notch/clearance anything else that hits or will rub. nicer to keep all the safety covers intact if possible, makes for a cleaner more factory install.
Man, sound's like Mister Rogers !
lol ya, but after a few noobs drive it the bike will match the converter. lol thanks. :P
it does, thats how even the stock clutch is held on.
If you clean, lubricate, and adjust as required then it would look like this.
You were hit by flying parts of a clutch you did not mount correctly as seen in your own video,
You clearly are not qualified to judge other people's work.
For your information the thread and bolt on these engines is 5/16 American Fine not "smaller thread than normal bolts".
Square key stock is not " a pin " .
If you need a part, then get the part number before you order and stop blaming others for your mistakes.
lol first off , i just read every comment first to see if my question would be answered there first lol n kudos on your reply's lol you reply to just about every question that is asked , lol even the ones you have already answered multiple times lol . any way my question is 1. does it climb hills much better afterwards , cause it already takes them quite well stock . and too would you mind un bypassing the govoner for a quick run n let me know the speed with just the converter on in mph ?
ive added 3 clutch spacers ( thin washers ) and im still just a bit off, its damn near shredded the whole belt. it seems like when it supposed to have tighten and take off, sometimes it dosent grab and then when it does i dont get the most torque because the belts not riding right, then when its supposed to switch to " overdrive " the belt isint alligned so the driver wont close all the way and the driven wont open, so my top end lacks. i have to get a comet belt and get this sorted out
im getting a baja carbon soon, one of the red ones, is the torque converter you have a comet 30 asymmetrical? the person who owns it now just ran a straight chain from the sprocket to the clutch, i know the clutch is burnt because of the ratio at it, hes throwing in tires, rims, fenders and brakes as extra parts,and also a comet 30 that needs a belt all for 230, sound like a good deal?
@gabriel56440 I'd say around 60-75km/h depending on weight, wind direction, road surface, and how well tuned the engine and bike is. :P
Do it right you say?
You have what appears to be a bicycle or mini moto brake on the rear of that mini chopper you built.
Your engine has 5 times the toque it was rated for and double the weight.
Marcel here actually has things that are safe.
And he is smart enough to ask for, and listen too good advice.
Maybe you should stop posting now.
You are embarrassing yourself
I don't know how I should say this so I will just come out and say it. That is not a torque converter. It is a variable pitch pulley system. There is a big difference between the two. That is why it is sold as a torque-a-verter not a torque converter. This has some advantages but it's not a torque converter.
@MarcelsWorshop
i have a mini baja and i guess it a older year because my clutch just doesn't come off if you pull it off you have to take off a pin, so when i got the clutch off their was a part that stayed on the shaft , so i cant take off the plate where the chains connect because i want to get in the engine because it been sitting for awhile
I know this question wasn't directed at me, but i know the answer, so why not? LOL. Normally an engine is strained less when a torque converter is added because it has to work less to accelerate, and when you start accelerating, the converter changes ratios so you will have a higher top speed. So you have better acceleration AND speed. Big bonus.
Hey man what kind of torque converter is that? And i have a baja MB165 with a 196cc engine and i want to put a TC2 torque converter on it from Go Karts USA.com but im not shure what it means to have a crankshaft that is drilled and tapped. I just need to know if i can put a TC2 on my baja without doing any work to it. so if you have any ideas please let me know. Thanks
