In my experience working as a technician in independent motorcycle shops I worked on everything from CVO Harley Davidsons to Honda CT90s. But there was one bike that always stood out with exceptionally poor quality. The Tao Tao 50cc GY6 (139QMB) scooter. And now I'm going to put this scooter to the test and find out if they really are little money pits, or if the issues with the bike are a result of the people who buy these kinds of scooters.
So I purchased a Tao Tao "Pony" ATM 50 and my plan is to make it my main means of transportation for 6 months. Yes from June 1st to January 1st this little scooter is going to be my daily driver. I'll be logging all of the miles, issues and expenses of keeping this scooter running in a log. Doing this will allow me to present a true cost of ownership at the end of this experiment.
The Tao Tao Pony 50 is based on the generic GY6 139QMB platform. They were sold under many different "Brand" names like Wolf, Bintelli, Fly, Rocketa, MotoBravo, Italica, and Dongfang just to name a few. You may be riding one and not even know it!
My scooter has been running lean since it was delivered. This is not unusual for a 50cc GY6 scooter. They are typically jetted extremely lean. This might be because it helps them pass the strict emissions regulations for the United States or to purposefully slow them down in order to meet the "Moped" regulations here in the US. Either way my scooter was running so lean I didn't expect the engine to last long. So I ordered a cheap jet kit off amazon (to stay in the spirit of the experiment with one of the cheapest scooters of all time).
There are a few reasons I did not just re-weld the bracket when I got to work or when I got home. The biggest one is I'm not sure what I would have to "charge" for that repair on my service sheet. In addition to that, most shops wouldn't repair something so cheaply made with such a high likelihood that it will fail again. But the main reason I didn't weld the bracket back on was my ethos of repair. If something fails, it's an opportunity to replace it with something that will better serve the machine. Rather than spending $70-100 getting the same unreliable part back on the tao tao I'd rather spend $40 on a lighter exhaust with better brackets that will be less likely to break in the future.
The exhaust and jet kit did make a pretty significant improvement in the performance of my scooter, but at the expense of the fabulous fuel mileage I was experiencing.
The parts I've used in this experiment are so far are:
Bel-Ray 10w40: amzn.to/3d623vR
Bel-Ray 80/90 Hypoid gear oil: amzn.to/2N3yFft
NGK CR7HSA spark plug: scooter911.com...
Brake line: www.scooterwor...
Performance Exhaust: amzn.to/2GfzQs4
Carburetor Jet Kit: amzn.to/32UtBTu
Drive Belt: amzn.to/3hC3rt2
Headlamp bulb: amzn.to/37huSVn
I make my adjustments to the mixture screw using this Digi Synch Manometer/Synchronizer: amzn.to/37B81nl

Never heard an American say “knackered” before, brilliant 👍😄🏴
I adopted "knackered" after watching Top Gear for years. :) That and "Hammond you Idiot!" and referring to somebody as a philistine lol
I haven't either - funny how Americans think you're saying 'naked'..
"Bob's your uncle" is another. I think he has watched Burt Monro/World's Fastest Indian...^^
Damn thank you so much!! I just bought my girlfriend a 150cc gas razor scooter. When it got delivered 75% assembled. I completed the assembly and my girlfriend was really happy and excited to try it out. Well that didn't last long when she went to ride it she pulled back on the throttle just a little bit and the scooter took off surprisingly fast I wasn't expecting it to be that powerful when starting from stopped position. She ended up crashing into the curb and now scared to ride it until I adjusted throttle
Nice to see you back..
The carb adjustment part you show in this video is extremely useful! I have replaced a cilinderhead and needed to dial in everything again. Was struggling with the carb, this really helped!
So glad it helped!
I have waited for this for so long.
Me too. Should be more often
For the plastic pealing? Lol
@@chucksvault nah for another vid. This is 6 months old
Love your videos. I waited 2 months for this video.
Hey Garret, great work on this series as well as your other content! As an owner of a Honda Reflex 250, I enjoy watching someone who is passionate about scooters- Keep up the good work!
"Knackered" haven't heard that one for a while haha. I ride a RK but for some reason I have become fascinated with your journey on this little banger.
I prefer the LED BA20D bulbs. most suck, but I found a couple good ones. Bad ones either don't work at all or flicker horribly at different revs, and require Capacitors and other components to be wired in to your harness to eliminate it. After going LED I haven't needed to replace it, They're also much brighter (which is great for safety). If you do get the incandescent bulbs still, go with the Sylvania bulbs, they're half decent. Also keep an eye on your Voltage Regulator if you pop another bulb again, that's one of the first signs that your regulator is going bad. Lastly, avoid the halogen BA20D's, they run so hot, they'll melt your headlight housing.
Also, while you're at it, put in an LED Brake light, you definitely don't want that burning out on you! They work great, and are easy to find.
Glad you're still working on it. Was wondering if plans changed..Hats off to you. I'm not a scooter guy but enjoy your channel and the serries.
I was so excited to see this notification
Nice work taking the time to do the upgrades and checking how it performs. Everything comes at a cost I guess better drivability but a drop in fuel mileage. Good luck with the Tao Tao
Glad to see your videos. Missed them.
Installed Keihin 20mm a few weeks back with 80/34 (pod filter) and factory exhaust saw 2-3mph increase. Just got similar exhaust. Thinking 85 jet as step up. At sea level here in NJ. Glad your back.
I'm in the market for a scooter and just surfing youtube came acrossed your series. First and foremost you have convinced me not to buy a Toa Toa, (thank you for living with it and not me) and second thank you for all the tips to tune a carb. scooter. Finally, thank you for all the laughs. All the little puns and comments you make just make me enjoy the videos. Subscribed and keep up the good work. And!!!! Bob's your uncle!!!!
I like that gangster GTA music when you started working on the carb
the last part is the most satisfy part! ooh yeah! Thanks for the great video! 3 and half tuned..noted.
Nice job ! I would've just bought a LED Headlight & did the upgrade 💯better visibility . Thanks for sharing 🛵👌
Any failure is just an opportunity for improvement 💯💪🏾
Thanks man! I'm rebuilding the engine of a Saga Retro scooter (w/ a 50cc GY6) right now and I think this will be very helpful to get it running well now that I've BBK'd it. I'll go back and watch some of your previous videos in the series to see what other things I can learn.
In at 3k miles and somehow magically haven't had any issues but my exhaust is getting rusty. Good vids bro been waiting for this for awhile.
3000 or 3000 miles
@@adambeforeeve5904 he literally said 3000 miles?
Or he said 3000 km because if he on a tao tao they read in kilometers! So once again the question still holds. 3k miles or 3k kilometers
Oh shit yeah 3k km my bad lol
@@JumpFloater4 I thought so thanks my good man
Thank god a new video.....seems a lifetime ago !!!! 👌
hi garret, i think you are a great presenter, your videos are not only informative but also entertaining... greeting from the south east of asia 🇲🇨
Hey, you’re one of the RUclipsrs I like at the start of the vid - so I don’t forget! Great videos mate keep it up 👍
Would love to see a vid of it being ridden, now it’s running right, also when the test is finally complete - a 72cc kit with A9 cam wakes this little motor up nicely 👍
The automatic choke adjust screw often being glued. It can release by boil it in water about ten minute. The basic adjust is: Heat it up by battery and put it in its place. It needle must shut its jet completely. When it cool down, needle rise and jet opening.
I have no problems at 5k. I wilk big bore it, bigger carb, performance cvt, performance exhaust, cdi, cone air filter.
@Anthony Callahan i can because i have air filter spray
That's good info. On pilot jet adjust. Turn out until nothing changes. Then lower idle. Screw Bill
Did 85 work for you or did you go 88
I was hoping I'd see some actual footage of you riding the thing before any extensive modifications, but I'm glad it's no longer killing itself from running so lean.
Very nice job rejetting and tuning. Love your Tao Tao jingle. Something satisfying about removing plastic film. By the way, my Honda PCX 150 gets 102mpg.
Dude...I just did this same thing you did in this video today... but when I did it, I snapped an exhaust bolt that mounts the exhaust to the engine block and...that...that took me all damn day to fix :/
Between the exhaust bolts, and the crappy exhaust pipe not being made for the Tao Tao (yes...I used the same one you did...even after I watched the video...) AND doing the valve adjustment and oil change... I am tired.
But the Tao Tao looks and sounds good. Now I just need to tune the carb ( which means I have to drill out the tamper seal for the fuel mixture screw :(... ) And then it'll be ready for springtime Funtime :D
Thank you for your kickass tutorial videos. You are a great teacher :)
Thanks for watching my friend and good luck on your future repairs! (they might be right around the corner...)
Used to help out many years ago in a friends chinese bike workshop. This brought back so many memories. I still think chinese stuff is getting better and better.
lol you're a very dedicated individual
What todays generation sees as an achievement or dedication is crazy.
Cant even dedicate yourself to a job these days, so i guess i see why riding a scooter can seem like a big deal to ya. Lmao😂😂😂
Dude I really like your show I've been working on the GY6 engines and scooters for quite a few years you're doing a fantastic job you got my vote Steve from Annapolis Maryland I like your attitude
Fuel consumption is a good point.
My Yamaha scooter is 90-110MPG, 125cc engine and 9kW
How can you resist the urge to peel the protective film? It's like the most satisfying thing that there is! Even if I could resist, go in the house and sit down, I wouldn't be able to leave it. I would HAVE to go back and peel it off!!
Pain is weakness leaving the body my friend
2000Kms and the exhaust drops off? Thats some quality welding right there!...
Little PoTaoTao. Haha Perfect nickname.
You're very thorough you got my vote Steve from Annapolis Maryland
I got the notification 2 days after it was released! Thanks a lot RUclips!
My sisters bf had a 50 that he gave to me. It blew literally every bulb at the same time. All of them 😂. So i just took em all off and im running leds. Doing kinda the opposite of you, going balls to the wall with a 52mm big bore kit and all supporting mods to see what you can really get out of these 50s. Made me smile to see Goldie again though 😌
Jetson's bubble cars! 🤣

drinking game : take a shot everytime he say 'so'
Or every time he wags his fingers.
What took so long for this video to come out I really love your series
Sorry my friend. I've been extremely busy at my day job and dont have much time to shoot and edit
Interesting to see some real data on the little scooter. After riding a Lifan 200 motorcycle for over 50,000 miles with no engine issues I bought a Chinese 170cc scooter with a Lifan EFI engine.
what is the name brand of your scoot
the tamper proof jokes just earned you a sub lmaooo
The videos are helping me with my 2008 Roketa MC-04 150... Well done and TY
Dude, thank you for the suggestion on carb jets! My scooter is running infinitely better, now!
Great video! Keep up the great work and thanks for sharing your knowledge.
I am very happy to see you are well and OK. Your videos are fantastic!!!
The assembling the exhaust pipe, it is easy when scooter is felled to on its left side, on some cushion.
i got a GY6 50cc scooter. a Kymco Agility. The exhaust was 1 of the first things to go, 20lb of rust less and a stainless steel muffler with a titanium headerpipe, the Tecnigas 4Scoot. Still turning some heads in the neighborhood after a year and a half, and that's with the DB Killer still in. It costed waaayy more then 40 bucks though, it was around 140 Euro which is around $155
love this series!!
If it's burning out headlight bulbs make sure your voltage regulator is grounded properly.
Hello, I have a problem, I have a Peugeot Speedfight 1 100cc that recently seized up/heat seized. It was not tuned. I then changed the cylinder, piston etc. It now starts up right away, but after a while it dies all of a sudden (as if you had turned off the key) and then I can start it right up again, this usually happens when I go over 60 km/h or uphill.
When I changed the cylinder etc, I also cleaned everything thoroughly, such as the carburettor, intake, new air filter, new fuel filter (there was no fuel filter before) new spark plug. I also removed the oil pump and put a metalplate with a gasket over the hole instead, I now mix the oil directly into the gasoline.
Some other info that might be important.
- When I drive over 60 km/h, it starts to make a noise from the variator (CVT), it´s sounds quite a lot.
- When it died, I tried to start it again while it was rolling and then it started right away, but it made a noise from the variator, like something "let go" that had been seized up, like a rubber sound, maybe from the belt.
- The variator belt touches the variator cover on the inside and has grinded a cut in the metal.
- In the variator, where the weights are, the belt does not go down to the bottom of the wheel.
- The clutch bell had turned blue from the heat.
- The place where the connecting rod attaches to the crankshaft had turned blue from heat.
- There was no fuel filter on it before. But i now saw there is an internal fuel filter in the gastank, can it affect the vacuum if you now have 2 fuel filters.
Please help me.
Regards
Andree.
Great video! Looking forward to the next update!
I like that widget! 25:25 👍🏻
..Aaand, Bob IS your Uncle!
I did mine to try to fix stuck float (oil in gas trying to track down) use a drywall screw to make an indent tap and turn some depot machine screw 0.7 5mm
I've got a taizhou mp50, which is like a generic tao tao with different plastics, and the exhaust bracket broke off the bottom of my muffler, so I just cut the bottom mounting bracket off, chopped the tip, tore the inside of the muffler out so it was no longer reverse flow, and welded a 2 inch piece of steel pipe off the bottom of a broken cattle gate on the end, so far its holding up great, i picked up 1mph on my top speed, and it sounds like a honda fourtrax now, even more so with the 100cc bbk I just installed yesterday.
Also that's a LOT of backing out on that idle adjustment, the PDQs I've got on mine want 1 and ⅞ turns for sea level, and I'm only at 1000, so that's where I stick em, if I need too, adjust until the exhaust smells right
Loving this video series
I have the 2018 Tao tao racer I upgraded the whole engine and trans that being said I was watching your video of the new exhaust and carburator jetting. You mentioned the high beam blew at 2000+miles it's funny because my head light blew at 2216 miles and I paid $23.00 for mine. Now I'm having a no spark issue that's the stater causing that but I can't fix it until March 1st when Amazon gets it to me. I enjoy watching your videos.
If you want to run 45+ mph do the 80cc kit. Big difference on acceleration. Just get a good quality kit. Or you can try some performance variator and clutch.
I'm surprised you didn't do an LED upgrade on the headlamp...! :\
Food for thought, how cool would I engine swap vidio be with a utility engine. 79cc predator, 79 Lifan. Something like that or maybe even go a little bigger like a 120cc Honda or Lafan. 212 Predator would be scary fast but maybe Overkill.
Is there a muffler to make a 50cc quiet and not give up any power that can breathe??I want the best of both??
Lmao just the kind of craftsmanship you'd expect out of a $40 pipe
Nice camera improvement
🎶 Living with a tao tao 🎶
update: Doing my second driver license test for 50cc yamah jog r 2013 air cooled in April. Wish me luck,
hope I manage to take care of it well as I proceed to use bus less/not at all.
Best luck! Keep it shiny side up!
I really enjoy your videos, so helpful!!!
SIze is a size, but it is important to know also the jet thread size. Is it M4 or M5 you can only check by measuring the jet thread with a caliper.
Can't wait to see this ped get mods! to see what's a waste of money and what actually works
I have a yongfu that I was given and it’s AWESOME
Remember how the float in my Roketa had gasoline in it? XD good times...
If main jet have not numbers, needle and caliber show sizes for comparison or size. Exemple: number 85 is 0.85 mm.
oH GARRET!! if i were 30 years younger? id be hunting you down! hahaha! you are definitely my guy! I have not seen a mechanic since the 70s when I was in high school and my first boyfriend in 1977 who was a tuneup Masters Pro, could look at a spark plug and tell you what was going on with the engine or carburetor in a bike or car!!! you're too young to know that tune-up Masters technicians were considered professional mechanics back in the 70s lol! I love your wit and your smarts!! and yes living with two taotaos has been rough, but I believe that if I can't fix something then I don't need it! lol.
Awesome content as always!!
I have the same exhaust on my stock 150cc Roma and it dose fantastic, I was In the same boat myself though didn’t come with the bolt I needed that goes with the clamp to mount and I had to weld/modify because the pipe they sent me was to Short too reach the head on my scooter 🤦♂️ upgraded the spark plug as well and runs and sounds amazing after everything I’ve done so far (not finished with it yet)
Nice

Be careful. Main jet only changes 3/4 to full throttle. Needle and pilot jet does the rest. 0-3/4. Not such an issue with a 4 stroke but a 2 stroke will lock up at half throttle with said changes 👍
George- "Is there a pinkish hue?"
Jerry- " A pinkish hue?"
George- "yes.. a rosy glow"
Jerry- "(•_•) There's a hue..."
Thank you! Very thorough explanations, nice voice and a novice comedian😂
My factory airbox on my taotao broke off where it meets the carburetor. Finally fogured out my air leak carb issue
American prices are a rip off. I got a full replacement exhaust with EGR valve and gaskets for £19 for my 50cc gy6.
Thumbs up for not leaving me hanging
I always wondered how they get the float bowl screws in the carb tight from factory
They actually are special break-away screws. They have a regular hex drive head on them initially but when they bottom out they keep tightening them until they snap the drive head off. Leaving behind a "tamper proof" fastener
About those weird headlamps 29:45, the only reason they use these is because they are slightly cheaper to manufacture.
Feel free to swap them for halogens.
Thanks for the video series. I know it may be an illusion, but it looks like there is an in-line fuel filter on the crankcase ventilator tube and none coming down from the fuel tank.
leovince hm titan is one of the best exhaust for this moped you can get it has all the things you need but it has a reduction in the exhaust manifold
we dont see any scooter swap shop stickers on that box we need to change that!!
Great job!
High beam always goes I put in a led bulb it's sill working now.
i need help, so i have a performance exhaust as well and i’m getting a new carb with a pod filter and i saw on one of the amazon reviews some guy used an 80 main jet and it was perfect but you used an 85 what should i use
It truly depends on your evaluation not just the mods. In general it's better to be richer then leaner. So, go up like 5-jet sz.
Then back down tell you start losing power. You should find your sweat spot.
Good luck to you!
Thank you
Sweet you did not give up on it
THUMBS UP from the Scrap Dog
If you have the front piece off I would put a better head light in than stock,I put a 1400 lumens in and can see everything and also in there should check brake fluid
I hate my brother for leaving that blue film on his China CRF250 clone (missing a few DNA strands I'd say (the bike, not him)). Accidentally saw the end of the video as i was clicking life, very funny.
I Loved This Video Made Me Buy A New Exhaust Just Now Throw Away My Stock Yamaha C3 Exhaust
My carb has screws I stripped one and I’m unsubscribing until you pull the plastic protector off lol
You do great work. Your self. But for someone who's not maniacal won't be able to do the job and it can become costly
My high beam light caught fire on day 1
I have a tao tao also. It runs great. It's pretty zippy. Picks up speed well right off and cruises nicely. I'm wanting more speed going up hilly terrain. Can that be achieved through carburator adjustment or through CVT upgrade or both? It has almost 5,000 miles on it; everything stock except CDI and coil. Thanks for the exhaust tutorial. Most useful as I'm replacing mine also. After that it's brakes. Oh another question I have is about wheel bearings? When/if they need replacing... Thanks again. I've enjoyed and benefited much from your videos.
