Project TaoTao : Carb & CVT Tuning, Airbox Restriction, & Keihin PD19J Swap : 50cc Scooter
Vložit
- čas přidán 11. 07. 2013
- This update covers carburetor and CVT transmission tuning, airbox restriction removal, and a Keihin PD19J carb swap. I go through the steps of getting a stock scooter in a good basic form of tune with an easy method and show how to remove the restriction from the air box's inlet. The tuning method is good for any scooter owner. I often use the same process on my two-strokes.

this channel is one of the best scooter channels on youtube, i love your dedication, thanks for all the info !
morkovetz Thanks!
-Yeah, what ever he said! :D
Oh, wow! Hard to find better instructional vids on the net. Right to the point and very professionally done. U rock, 90.
Great videos. A little over a week ago, I bought a dead scooter for a couple hundred bucks and knew nothing about it. Now I've got it running like a top, with no outside help whatsoever. And, I'm confident I can keep it going should anything else spring up. Thanks a ton. Cheers.
Thanks for this series. I've been wondering about these modifications, I appriciate how you've laid them out. A lot of ground is covered here.
Best carburetor tuning channel 👍👍
I'm not mechanical at all but I bought the taotao pony 50 I love it and want to learn more. I sure am Glad there are people like you, I dont understand anything your saying but its definetly awesome that you do.
Good to know there are people know how to do these types of things
These videos are gold. Thanks good Sir :)
Finally video's with some great information, I love scooter tuning and although I have a 2 stroke high performance speedfight your idea's are simple but at the same time brilliant if you don't have access to a rolling road.
Its nice to see someone who isn't barking on about doing 80mph but brilliant tuning tips and if your getting into tuning your scooter I would deffo watch these videos as they make a lot of sense even I got alot of tips and Ive been into tuning since I was 16 and had a AR 50 20 yrs ago. All I can say is great work keep it up as your tips are spot on and well shown.
Thank you. Part of why I do what I do is because I also grew very tired of everyone and their mother claiming to bolt on a cheap BBK and go 70+.
amazing videos. Very informative Thanks you for all the uploads
Another great update great job
Unbelieve you do that all also for us, ty very much
I'm glad if it helps. I love scooters and engines in general.
quick question, what should i do, when im riding my max speed is at 35mph(almost full throttle), and when im at full throttle it goes like 1-3 mph slower, whats the problem?
90GTVert What brand sliders are you using or would recommend? I just got a KOSO variator with 6g sliders from scrappydawg but my 6g rollers are much faster with acceleration. Do would you recommend buying a "performance" clutch kit or just replacing the stock spring and/or shoe?
You are soo good. I thank you. Professional and informative and humble. Be well!
Thanks!
The sound of power. Tearing up the back road asphalt through the corn fields.
White knuckle fun in flyover country.
as far as your tests I am impressed with your knowledge all of mine is self acquired had to start working on small engines when I was little had a minibike and it sat too long one time and I had to take apart and clean my carb was my first learning session got into it right then
I read performance books for bikes/cars and such, but I have to have my hands on something to really learn it.
Mr Taylor thank you for your help , really it was the filter ,the emissions, as to make a good statement ,that will not only profit ,Powersports ,The Scooter is concidered to be a bicycle , and you has no need for Lience Or Insurance, they or not motorcycles .
Great info
Thank you.
Thanks
Saved me hundreds of $ and man hours. feel like I owe you a stake dinner and a beer
i tell everyone to work on their own scooters or cars i learned my shit from you tube videos.
yup nice bike man I actually get only 40,now but only paid $200,for the bike got it operating like new
You sounds like Eugene from the walking dead;) thanks for the video man.
It IS him, silly! All he has in the W.D. universe is a scooter, a toolbox and a camera, these are the found footage videos of him trying to make his scooter zombie-proof, that's why he has all the gadgets installed, more power for outrunning zombies and roving gangs, and great MPGs because gasoline is so scarce!
Nah sounds more like JafroMobile in Virginia.
Sorry guys but it’s spot on propane salesman, Hank Hill.
I thought it was Karl Childers. Alright den.
Nice video subbed ;)
Thanks. This one is running hotter CHT than my 2Ts. My 2Ts stick more around 300-350WOT according to my gauges... but then I also don't have to run them wide open all the time when cruising at 30-35, so the 4T is seeing a lot long WOT times. The probe is about 11-12" from the header, maybe 1-2 o'clock position, about 3/4" spaced up to not block the small pipe off (pics on forum). It would work on a 2T, but oil is hard on the sensor and a special adapter (Koso) should be used. Never tried it.
I’d like to argue that your lean bog after removing intake restrictions was a dead giveaway that the engine is capable of making more power but limited by something else.
I want you to know I admire your dedication to those small engines.I do not have a shop but have done 100's of different tests.One thing worth sharing with you is my results on my gy6 150 cc concerning the air fuel mixture screw.Let me know if you're interested.Thanks
Sure, what ya got?
As long as there is no leak where you sealed off the head, should be no trouble with PAIR removal and tune. Take a look at the plug. Easy enough to see if it's fouled. If you run it WOT first and shut the engine off, coast in or ideally brake so the engine totally stops. Then when you look at the plug you'll be able to see if it's wet or dry to give you more clues. Check grounds and other connections. Make sure the plug boot and wire are secure.
So ,you guys help people get back and forth, and it's cheaper home boy no lie y'all Helped those that needs transpo ,home boy ,with your You tube ,training and hands on ,and Your ATV2 ,CTV.,Powersports and Honda Products ,
It's a Trail Tech Vapor. Lots of places sell them, but I got it open box at a discount on eBay.
Have you tried lighter rollers or maybe a stiffer contra spring? Could be dropping RPM on the way up till you end up out of the power band, then it really struggles.
nice video
Thanks!
your welcome brother.. i have my new honda click 150i. new release here in the Philippines. thats why im searching for idea how to get better cvt set up :D..
90Gtvert your awesome just want to say I think we could be good friends I too have been experimenting with my scooter I have. 04 elite 80
It won't usually close until everything starts rotating. You can turn the pulleys by hand sorta feeding the belt while the engine is off and you should see that it starts working it's way out... or make sur ethe belt clears the cover and bolt it back on then start the engine. Let it run a few seconds and shut it off and re-check if you'd like. If it stays there after the engine is running, then there's a problem.
Yes I'm probably going to get a new carburetor for cc50 mL 2012 Tao tao
I took the pair block off plate off. Looks sealed good. Maybe I spray witb carb cleaner see if it idles up. There are only 2 grounds on the bike at the v cvr. Maybe the other end came loose . The bike ran great plug chop had been done. I did move up some jet sizes thinking that was problem becaus temp has dropped here but that did not remedy. Gonna check grounds again and change pluv. Tha ks for the help
I ported my intake , opening up the 90° turn mostly, but the main issue was port matching, the ports were off substantially! Nearly 1/4 of the port, I bought a new intake, it was considerably smaller, and had a major reduction in size around the 90° bend, it was about 14mm, just over 1/2", like the tip of my lil finger ! I opened it up a bit, but it was nothing near the size of another I had, so I ported it and matched it to the head, I would like for it to be about 2mm larger around the 90° bend, with a nice sweep, it fits the carb and head nicely, I straightened the port under the valves, and blended around the valve guides, id like to eventually go to the 52mm bore, and 44mm stroke, maybe get crazy with some machining, and move to a 57 mm bore, should be 100cc plus a couple right? I haven't done the maths, maybe 98-99cc but no replacement for displacement! It would be cheaper and easier to just swap in a 150cc, (with a big bore),
You'd have about 112cc if you could make a 57mm bore fit. All said and done, I'd guess you'd fair better swapping in a GY6 150. A lot of people have had enough trouble with reliability with even the 52.4mm bores. I'd also assume you'd have pretty much no material between the bore and the studs at that point, if there's enough room to do it at all.
I probably could get 70,no problem but it's quick on the start maybe later happy holiday
Stephanie Spangler (can't reply to your message) : If you watch @ 6:56 or so I said I changed to a 90 main jet in the stock carb so it worked with the more open airbox. In stock form my stock carb had a 79 main jet. Most use 32-35 pilot jets stock.
yes you did. i just realized my misinterpretation. thank you so much for taking the time to share your knowledge and experience. My TaoTao50 is much happier now.
***** u were right im still fukin with this carb.the fuel mixture screw is too far out smaller pilot? i did what ur video said on fuel idle mixture adj.
If the mix screw is way out, try a larger pilot jet. On these carbs it controls fuel so when it's out it's letting more fuel pass and if it's in it's blocking off the fuel passage more.
i read someone with a scooter like mine the vip champion taotao couldnt get it to run for shit it had 23 miles on it he had to return it carb issues. id bet the farm on it you could get it right.
Hard to know. There have been some pretty poor quality parts out of China at times.
I have 2014 Jonway 50cc and was wondering what would be a good pipe to get. you seems to know a lot and give good tips. Thanks.
At one point in one of the videos you mentioned a good starting point for the air fuel mixture screw, was that like 1 and 1/2 turns out or??? Thank you love your videos awesome information well-presented
1.5 - 2 turns out is a common range for a starting point.
Great video! Are 4 stroke engines hotter at the head than a 2 stroke?
I like your air-fuel ratio meter, have you tried to use one on your two strokes? Would that work? Where did you mount the probe, or did i miss a video?
-Wish I knew Half the stuff you do brother! Lol.. I know next to Nothing of what you spoke & your experiments, but I bought a 50cc Dongfang about a month ago & 'performing' a slow rebuild. Just got the new carb today, & can do the install, but tuning?! Ummm..lol. Regardless, your vid helps! -Ride safe!✊😎
Gotta start somewhere. I've got plenty to learn myself.
It work for me did same thing my taotao thunder change jet to 90
Shouldn't be like a mirror, but they aren't usually as rough as you'd think. Rough it up with some sandpaper or emery cloth. Give the clutch shoes a quick once over as well. Clean both with brake parts cleaner before you reinstall.
by the way , you can mount a 100cc 4 stroke engine set on that sucker ... really gives it a kick
Ok got got the cvt and clutch swapped. I still have issues . It was jetted correct running excellent then just started runing like it is missing. Sometines it pulls great runs great but its sporadic. I swapped cdi, coil ect with my other bike nothing worked. I checked valves went over all wiring checked timing pickup ect .
90GTVert, do you have training classes for tune ups, modifications, etc? You should. I know I would consider attending.
+Robert Jones Public speaking and I don't get along well. lol Videos and the site/forum (49ccScoot.Com) would be the closest to that.
i wondering if you could help me i have a Gilera Runner sp50 with sports exhaust. Everytime i go up an hill it goes half way up and bogs and stops? can you help me please?
The debris gets old (I have times when I'll pop tire after tire with screws and nails), but worse than that are texters and the people that stare at something and steer at it.
Awesome! Long intake runners helps car engines make more low to mid range TQ, has anyone heard of someone adding length to the intake of these scooters? Either a 1" spacer under the intake, or a pipe and boot between carb and intake , or both? Being these little guys sound their day at near full throttle, it may not help with top speed, however maybe it could help get ya there quicker?? If done properly maybe it could help top end slightly,
I'm sure it has been tried, but it's not a common mod. Most intake mods are due to fit or port/carb diameter changes. With these engines, gains at low RPM aren't usually worth a lot because the CVT keeps them at fairly high RPM so much. For all out performance, the best bet is usually to focus on making the CVT hold RPM the best you can at WOT and focus power making efforts on a somewhat narrow range.
My rear clutch stay open. I used my fingers to smash it open so I could take the belt off. Well it stayed that with the belt riding all the way down in the rear clutch groove . I just put it back together that way. Now I realise there is something majorly wrong. I was in there and replaced the variator. But I am certain the contra spring shojld make clutch snap closed?
It was an eBay seller, forget the name, but I know they didn't have any the last time I looked. Other sellers did.
can you please post the site where you buy the scooter ?? does it come with aproval documents ? in romania we gotta go to the R.a.r (dmv i think) to check it for road safety / conformity with the papers , i hope u know what i mean , registration papers ...
I think the reason for not gaining any power after the airbox restriction removal is that doing so, u increased the pressure to the venturi and thus lowered the velocity of air, so ur carb was getting about same amount of air but dint pull same amount of fuel thru the jet.
More about it here: www.vmaxoutlaw.com/tech/airbox_mods.htm
one thing you did was removed the hose from the air box do not do this instead leave the house with the cap for stability and remove the filter in the air box. after removeing the stock fome filter buy a 38mm coin filter and slip it over the end of the hose you removed this way you will get more airflow and better performance the stock fome filter restricts air intake but in most cases you still need the hose and box
I got the keihin carburetor, moved the split washer to the top groove, adjusted mixture screw a quarter to the left. I see a positive difference in take off and top speed but what can I do to handle inclines better? Thx...José
Lighter roller weights are usually the easiest option to help them pull hills a little easier. A big bore kit really makes a difference in power though, and should be a nice mod for anyone needing to climb hills.
I have a 50cc 2012 Tao Tao believe it has a carburetor issue I'm going to have to change it it will not hold an idle the only way to get it to run as you have to constantly rev the throttle
You could try cleaning it first and adjusting the idle settings. If it's a stock carb, it may be just as well to replace it with something that has an adjustable needle and no sealing methods.
Where did you get that digital instrument cluster! That's awesome!
Thanks for your work and sharing. Are you on the NC Coast? I want to live in farm country w/ saltwater access.
I'm in MD.
I guess the only thing I haven't done is change the plug. I'm runni g ngk now maybe carbon fowled? Seems the problem started occuring aftr pairs removal. Ang ideas?
the carb you mention I dont see it online anywhere, its the pd18 not 19, whats the deal?
Thanks for the vid. It helps to understand but i need more info.. I have a 49.5cc icebear mojo trike. I put a 50mm/100cc bbk on it with performance valve head ngk spark plug racing coil/cdi and a 20mm carburetor Stock jets airbox/ exhaust about to upjet tring 90# than maybe 88. Timing set tdc gaps at .005.. Im having "cold" start issues i have to hand choke it for it to start once its warm it starts fine. Runs good i think but i dont have any real experience. Also from a cold start there is a small/low metallic sound upon start up and high revs right after start up. It goes away fast. Im told some performance heads sound like that idk?.. Could the cold start be just jets or air/fule (set 2 1/2 out) cold outside small stuff like that
It could just be a bit lean and will straighten out once you get the carb tuned.
hello great video by the way .. i have a ruk clone with plenty of mods. from 1 ¼ exhaust, stroker crank cdi trans kit 20mm carb with #91 jet lots more etc.. my problem is, with the factor air air I'm not get enough air and with a UNI filter its too much air. do i need to up the jet size to compensate for more air?? plz HELP!!
You should try a larger jet with the UNI or a smaller jet with the stock airbox.
dude I'm being Stolked,real tough man ,get about 9 of them ,just like a car lot pay as you go ,guy ,cause really people feel like I ,owes them my scooter ,they crazy, help Lantio people and Carccains people cause they good on gas .
I am planning on upgrading my 49 cc tao tao scooter to a 80cc with a big bore kit form rolling wrench, what carburetor to I need to use with this upgrade, can you recommend one thanks and keep doing more videos
+michael paradise 19-20mm without the factory sealing would be fine. Pretty much any that you buy shouldn't be sealed. That's only on scoots to meet EPA regulations. You can find them on ebay and from places like www.partsforscooters.com/?partner=49CCSCOOT . Keihin is good if you can find one at a reasonable price, but even the knockoffs do fine for most. Just the sealed stuff without adjustable needles should be ditched.
My 2013 taotao 50 cc moped isn't running right, it bogs down when i give it gas and doesn't idle good, i have a new plug and new gas filter and new blue high performance racing cdi, and went synthetic with royal purple engine oil.
if your filter is restricting fuel it could have an effect aswell it could be the air filter if you scooter is older or you run 87 rather then super i suggest seafoam
Holy crap... how did you get kenny powers to do a voice over for your video?
so after installing the pdj19 keihin I noticed my plug fouled black...should I be adjusting the screw on the carb to the left or right? is lean responsible for the foul or rich? does turning the screw to the left make the carb leaner or richer...sorry for my ignorance....
Rich fouls plugs. Lean would leave it clean. Turning the screw in would lean the idle mixture. You may have to go over the whole tune, not just the screw. Here's a bunch of info : www.49ccscoot.com/faq/carbtune.html
I have a 90 2001 Polaris scrambler I picked up for my son.im not rich but try to give him stuff I did not have.i got it running great then all of a sudden it stopped!spark is good and consistent.seems to be lacking some fuel.when I spray propane in you can hear it try to start.can the card get messed up that fast?there is a fuel filter on it.
Check the whole fuel route. Could be as simple as a pinched hose. Make sure hoses are good when weight is on the ATV.
where did you get that tach? hhow did ou install it so nicely? also I have a question, the air intake hose has come off my carb. and for the life of me i can NOT get both ends of the carb connected to both hoses. I was thinking an easy fix would be to buy those little cone shaped air filter, but i know when theres too much air they dont run, any tips?
+Nicholas Butler Here's some info on the gauge : 49ccscoot.proboards.com/thread/8614/trail-tech-vapor-information-installation
Try loosening the mount bolts for the airbox then installing the hose and maybe you'll be able to attach it all and get the bolts tightened again that way.
i'll be happy to cruise at 50 and climb hills no problem.
i got a kymco agility 50cc...what can i do to get more out of it? big bore kit?
Big bore kit is the best mod IMO. Makes quite a bit more power at a reasonable price. Tune the carb and CVT when the BBK is done.
At 1/2 throttle and wot my scooter just boggs down will not do over 20mph. Everything stock. Changed to a new carb and same issue. Any idea?
Airbox issues or filter change? Fuel supply issue?
Hello and thank you for these great videos I have a crazy question maybe you could answer, I bought two of the same scooters one of them does 43 mph right out the box which is crazy? But the other oneCan barely hit 25 what would you recommend I try?I have changed the plug,carb,cdi, and that fuel vacuum thing to no avail. can you recommend anything else because that particular one is still super slow?
Have you tried any of the parts from the faster on on the slower one? Like, did you try it's carb or just a general replacement carb? It could be as simple as a tuning difference. Could be that one has a restriction somewhere. Could be a defect, like maybe one has low compression.
No sir I didn’t try any of the parts from the other scooter, no I wish I did one at a time dammit man? I just kept getting stuff on Amazon you know hoping something would work I think it’s a lemon or restricted like you said I. Hey thanks a lot for responding looks pretty peaceful out there where you Live, got a nice clear mind to make great videos well the rest of the world as dodging cars lol. hey are you have a wonderful day and thanks again
Great videos. I bought a new taotao and did replaced almost everything you replaced. It runs way better now. I can’t seem to find the KeiHin carb online and if I do I find, I can only find the cheap ones that looks nothing like yours. I know you bought yours from a local store. But did you find any legit Keihin carbs online?
I bought mine from an eBay seller, but they no longer have them. The Keihin part isn't essential. I actually think most replacement carbs that are fully adjustable would do fine. The stock carb wouldn't bother me if it were adjustable, but finding the right needle wasn't worth it to me. Easier to get a whole new carb.
Ok thanks for the info and btw your videos were really helpful. 👍👍👍👍👍
90GTVert ... so the toatoa needs a 19mm or a 20mm carb... if it was in your video I missed it 3 times now
I need your help I rebuild my gy6 50 from top to bottom all new parts . I need to ask you about a 21mm pwk carb. And the best air filter I can buy as the carbs on the bikes don't last me long . I have had like 3 carbs over the last 3 years . I will try to hit up your tip jar soon . And thanks much
Some of the folks on the forum could give you better advice with the PWK. I have never used one. If you get a quality brand... like Keihin or OKO for example, then it should last for years. I've used UNI pod filters, usually the dual layer, and K&N filters on 50-150 4Ts without issue, though I prefer the foam UNIs. There's no reason that combo should need to be replaced regularly. As far as what jetting to start out with on something like that, I have no idea. Again, no experience there. I have heard forum members say that acceleration is dramatically improved when you get rid of the CV carbs though.
here is a vid from this morning with the hoca installed. seems i could use lighter rollers. was really windy out. I need to up may main jet. the bike make best power around 25mph. i am waiting on a tach.
check out jami kay channel for vid. it wont let me post the link. Taotao 72cc bbk
is there a pink cable that I should be snipping now that I've unrestricted the carb? I imagine such cable must govern any mods...thx
Shouldn't be on the TaoTao.
also have you heard of people taking the outer lining of their clutch I was interested in that mod because it's free only fear would be the gyroscopic inertia on the clutch though I have heard it's harmless
A lot of people drill the clutch to lighten it. Not sure about modding the outer lining.
what would be the stock rollers in my 2015 taotao 49cc? what minimum new g rollers will alleviate incline? many thx
Can't tell you for sure, I can only guess it may have the same 5g rollers that I had in my 2013. 5g sliders are a popular choice for getting the revs up a little.
Just curious about your tire. In the videos you accelerate through wet grass and then out of a puddle on the road. What kind of tires would you recommend for wet street conditions? Awesome instructional videos!
This thing is underpowered and I'm heavy, so it's not so demanding for traction, but I'm just using cheap Kenda K329s and I had Vee Rubber on the rear at one point. My two-strokes have more traction issues, and I've had good results with Michelin Pilots on them. Lots of tires work pretty well, but stay away from max performance dry weather tires. Michelin Boppers are probably the worst I've had. My first 70cc would spin the tire bad in the rain with one of those on the back.
Thanks. Even the tread on the Boppers does not look good for wet weather.
finally some ta ta action maybe u can help me my 2014 ta ta is well temper mental very hard start when it's cold and refuses to idle plus when it warms up the idle constantly goes up and down it's driving me crazy lol got any ideas plz j from Indiana
I'd start with a valve adjustment and see where that gets you.
czcams.com/video/s0K-ytyjOFg/video.html
What would be considered the safe temperature range for the head? Also what should be the max rpm?
Temp will depend on your gauge setup to some degree. With any of my CHT gauges I tend to get used to the range it runs in when in tune and anything significantly higher is an issue. Peak power for me was 7800-8200 so there really wouldn't be a need to rev too much higher. Valve float is somewhere above 10,000RPM for most of these.
Is that Oklahoma hwy signs I see? I'm your neighbor in Arkansas. Lol.
Was wondering would you mind try making video's on a 2017 taotao racer 50 as well too plz?
Don't own one. Same engine as this TaoTao though, so it applies quite well.
You changed the main jet to 75, what did you set the pilot/ idle jet to? Also, I am a big guy, 230lbs., what slider or roller weights which you suggest just to go 35mph on flat roads?
I made no change to the pilot jet because it was not necessary. The mixture screw was able to control idle mixture just fine. I'm close to 300lbs so what I used here may be close for you. There's no 1 right answer, especially since contra spring stiffness can vary.
is there a reason you don't do plug chops? is it just the wide band O2 sensor tells you about what a chop would?
I don't really do 'em on scoots without the sensor (all the rest I've ever owned or tuned). I find them unnecessary and expensive, since real plug chops involve cutting up spark plugs after one test run. The exception being if something is particularly confusing or difficult to me and I need all of the help I can get.
hey also wanted to know what would cause a scooter to jerk when you pull on the throttle when you first start going could something need adjusting to stop it from trying to bog out
The accelrator pump causes issues on some of these. You can try adjusting the mix screw and see if there's any improvement or try changing needle settings.
Okay im gonna have to try that over the weekend i just hope that i dont screw the carb up its a cvk carb
What all modifications can I do now that I dont have a rev limiter, a rebuildable carb, & went from a 50cc to a 80cc BBK? There isnt a pink wire on the cdi box & the carburetor filter is gone along with the air box restriction. What all do I need to do since I installed a 80cc BBK
Put the filter back in the airbox. No filter will reduce engine life and it's really not gonna cost you much or any power if it's clean. Tune the carburetor.
Then it sounds like a good time to work on the CVT. At least tuning with weights and springs. Maybe try a performance variator.
Many also like the gains with an A9 cam.
I went & bought a A9 cam when I had the 50cc head & jug & didnt see any hp gain anywhere. But when I got the 80cc I felt a good hp gain with the A9 cam. I will get a new filter for the box soon. I have factory sliders from a 150cc I had at 1 time but they wont fit a 50cc variator but I wished they would. Do you know what gram is factory for a 50cc? I have blue rpm springs but no blue contra spring. I also have a new belt ordered and waiting on it. The factory belt busted at 11,000 kilometers & I think its because of the clutch. The clutch & variator housing is a poor design. The inlet hole is allowing water to get into the belt, clutch &, variator casing causing rust to collect on the clutch. I made a snorkel for the airbox to stop water from getting into the box. I did little mods but isnt much. It didnt like being rode in the rain. So the snorkel for air box & tape on the inlet hole of the clutch worked but I dont like clogging the hole so Im working on snorkeling that as well so no water can get in. If I ride in that puddle like you did it wouldnt make it out!
Is there possibility to make a video from 50cc to 100cc Correctly how to doo upgrade
Yeah not a lot of people are going to do that it's cheaper to get online and get a big bore kit for 200 bucks comes with exhaust, intake, carburetor, performance air filter, CDI, NGK plug, performance cam and lifters, transmission upgrade and gaskets, performance fuel line.
Could somebody point me in the direction to the carburetor he showed in the video I looked all over the Internet and I couldn't find it
That stuff comes and goes sometimes. Check ScooterTuning.Ca and PartsForScooters as a couple of sources for good carbs.
guys I ,has a good TAO TAO 50 ,ok ,and some cut my belt, so I ,replaced it ,and has no ,no power ,to up hill ,new gear,oil ,plug ,lines or clear , B 12 ,corb.cleamer ,what can I , do for take off power ?
Are you sure the rollers are in correctly. If you didn't take the variator off to check, they may have fell out of place when there was no belt.
i replaced my air box with a air cone filter .. and now it has no power ..? i give it gas and it will not go .. what coukld i have done wrong .? should i put back the original air box .. i did not do any carb adjustments ..? please help if you can ..?
It's running too lean. You either need to reinstall the stock airbox or get some jets and tune the carburetor for the new filter. You can get a jet kit (part # 114-49) from the site below if needed.

Nice instructive videos! What pilot size were you using on the aftermarket carb?
Thanks. I used the 33 that came in the carb.
@@49ccscoot thank you for the quick response! I do appreciate it very much!
@@49ccscoot also where did you get 4.75g sliders? I can’t find any. Or did you use 3-4.5 and 3-5 to get 4.75? If not would it be ok to do so as long as you alternate sizes?
@@elvis7094 Yeah, I mix weights to get the 1/4 gram increments. They must be staggered. So only 2 different weights of rollers or sliders, call them A and B. Put them in A, B, A, B, A, B so it is balanced. You can also modify weights to whatever spec you want.

@@49ccscoot thank you very much
What could I do to be able to look into getting a speedometer like that?

Is that an aftermarket speedo? And if so, where did you find it? Also is your engine still a stock 49cc or have you added a big bore kit?

It's stock, just a little tuning.
