- Опубліковано 20 сер 2024
- Quick ride around town on my 2018 TaoTao ATM50 with a big bore kit, A9 Cam, Larger Carb, Aftermarket exhaust, and 1500 rpm clutch and torque springs. I'm still dialing in the jetting on the carb, hence the loading up on takeoff. Also I've adjust the lifters to .004 and .005 but they still tick like crazy. I've also tried .002 and .003 and still ticked, oh well doesn't seem to hurt performance. Filmed on a gopro Hero HD on 720p60fps.
Love it nice big bore nice deep sound and speed
Thanks it was a fun little thing!
I added the Big Bore kit as well, and had the same clicking sound. I to re-adjusted the lifters to .004 and still made the clicking noise, so I added some Lucas Oil to it and it help quiet some of the clicking. I think is just needs some breaking in time.
Yes I’ve adjusted mine so many times, so far .003 seems to be mines sweet spot, but every motor is different
Mine makes the same clicking sound as well
@@christophercrowe7284 mine went away when I changed to 10w40
I do them by feel is how I've always done it. And best oil mobile 1 motorcycle racing oil. Can take the high rpm without the oil breaking down.
They are tap valves
Until you change tge final drive gears. Plane abd deck the head. Flow the intaje and exhaust ports. Go to a Mikuni carb. You have done anything but bolt on parts. My QMB139 59cc will roll 68mph like a motorcycle. I run 16.16 1/4 mile at 68mph.
Yes tune that carb sounds like it's flooding out at idle. Adjust idle mixture screw or larger pilot jet 😉
Yea I never could quite get it perfect lol
My set up is 88cc 52.4mm kit 20mm carb #95 jet A9 cam 5.5g rollerz .004in .005EX ncy cdi ncy coil free flow exhaust and im at 56mph might try out that final gear stock clutch rpm spring with a 1k torque spring
How high above sea level are you?
I was in NC at the time of the video, no idea on altitude
after i put a 50mm cylinder and piston my whole engine shot i think because i was riding it and at made a huge noise and shut off
Nice. Mine died after about 1400 kilometers.
Don't suppose you could take the time to list enough info about your build that I could check the parts out on a site somewhere? There are a LOT of big bore kits for this thing. Be helpful to know which one you actually purchased, etc. Thanks in advance.
It was a big bore kit made by a company called grownsun, all the parts can be found on Amazon. I don't have links since it's been 2 years already since I bought it all
At how many miles did you add the bif bore kit? Carb. jet. ? exhaust change. Speeds ? Bill
I put the big bore kit on after about 300 miles, I used a stock 150cc carb as well, not sure on the jetting, I just adjusted the mixture screw until it ran good, exhaust was a growsun aftermarket exhaust that's not made anymore, actually the big bore kit was from grownsun as well, I was told it was a good name brand kit, just discontinued. I also changed the weights and springs in the cvt, and used a kevlar belt to last longer. Was still running great for me when I sold it after 3 years running the big bore kit and around 2k miles on the scooter too.
What kit did you end up going with? And did you doing anything to your carb tuning or any cvt upgrades?? Thanks for any info, building a stunt qmb139 and wanna do a bbk to give it more power
Mostly people get bigger carb
Yep I used a stock 150cc carb
Nice and quiet
the gopro didn't pic up the audio that well, it was actually quite loud with the exhaust I put on it lol
@@Z3CHYD still, you got plenty of speed out of it, so mission accomplished
Big bore give u a bit but the main upgrade should be the cam.
I did upgrade to a A9 race cam.
Got a good sound to it was it the 50mm bore 47mm .
my scooter tops out at 30-35, ive changed the cdi to a racing cdi, i put in a 100cc big bore, 3 5.5g and 3 5g rollers, bigger pilot jet, cleaned the airfilter and still wont go over 35? what else do i need to change?
Dang that’s as fast as mine did stock, not to be rude, but how much do you weigh? I know they do struggle even with a big bore kit if the rider is more than 220lbs. Other than that I’m not sure what could be making yours so slow, you’ve done all the right mods so far
Z3CHYD im 160 lbs and idk whats wrong either, some people suggested me i change the belt and i ordered up a new one, im also probably going to buy a bigger carb if the belt doesnt help.
I replaced mine with a kevar belt, but that’s just a tougher belt, nothing to make it faster. Also I put on a 150cc carb
Do these scooters have a restricktor ring in the cvt?
Mathias Håland what does the ring look like?
When you did the clutch spring did you only do the large contra spring or the three little springs
All of them, they normally come as a kit
Im looking into doing this to mine. 2 years later does it still run?
Yep it does, I sold it to a guy a bit ago but he's still out riding it
I have a 2020 VIP 50cc TaoTao. I'm getting ready to put a 80cc-big Big Bore Kit in it in tomorrow. What's going on with your bike is it still running after 2 years? I'm just wondering if mine will be around next year.
I ran mine with the big bore kit for a little over 2 years, I've sold it since then but last I heard it's still running just fine! I had used a "brand name" big bore kit, a company called Growsun. I'm not sure if they're still around anymore or not though
@@Z3CHYD Thank you for your time man appreciate it
What's your top speed on the vip 50? I have the same bike but dont know if a big bore kit will increase my speed or not
I get it because I didn't like traffic crawling up my ass scared the hell out of me with the 80 I didn't get a whole lot of top ends I got a lot of quick off take on take off the thing you want to do to get higher speed is your final year for you like I ended up doing after about the six different Big Boy pics ended up with 105 three times it blew up every time finally bit my crank I ended up doing what I should have done in the first place and put a 150 in the 50 it's now 150 swap nothing ever happened to it fires up every day the thing about the big boy kids is if you have a small motor it says Chevy motor keep your 50 put an 89 cam and your final gear that's what you want to do if you want to keep the 50th that's the best you do final gear releasee and forget the typos I use voice to text cuz my arm is f***** up I can't ty
speed
Did you face any problems with the electric start when you installed the 82cc kit? Mine doesn't have enough power to rotate the engine even when i connect it directly to the battery.
Sometimes in extreme cold I just use the kickstart to start it, but really even with be big bore kit it still starts it just fine for me
@@Z3CHYD Ok, do you have any idea what could be wrong with my scooter? It doesn't spin the engine even without the spark plug.
Do you mean the engines itself won’t turn at all? Or just the starter won’t spin it? Does it still turn over with the Kickstarter? If it does then your starter might just be wore out/bad. These Chinese scooters parts are cheap and are hit and miss with reliability
@@Z3CHYD I mean that the scooters engine doesnt turn over. I just replaced the starter motor yesterday and it still didnt want to turn over the engine, the starter seems to not have enough power to turn the engine. It turns the engine in very short cycles slowly.
It turns like in this video but slowlier. ua-cam.com/video/fWDvpv_T_54/v-deo.html
And also, my battery should be fine becouse i tried to jumpstart it from my cars battery.
I'm adding the same big bore kit. My main concern is losing power going up hills. I don't like holding up traffic. Are you able to power up hills at 35mph?
Yup I can make it up most hills around 40 miles an hour and my big bore kit has lasted 1000 miles so far I normally drive it on nice days and weekends
Z3CHYD thanks man, I appreciate it! I don’t feel comfortable installing it myself so I’m going to have a professional install the kit and new rollers. I did everything else myself. Exhaust, carb, air filter, cdi. Anything else you suggest?
I change my CVT spring to a 1500 rpm’s spring and that made a big difference with acceleration I suggest that too for getting off the line faster
Z3CHYD thanks again!
No problem ✌🏼
Years later, has it ever broke down on you or misfired for any reason? Also what did you do about belt slippage as I heard thus can be a factor
I only ever had one time where it shredded the belt, but that was because I had the original belt still on it, I later upgraded to a kevlar belt and never had a problem. If I let it the scooter sit for too long, it did become hard to start sometimes. I always ran 93 octane fuel, and used fuel stabilizer in the winter, and that definitely helps
Sund good
About how much do I have to put into it to get what u got going on?. I just bought my first 49cc scooter
Probably $200 or less depending where you get your parts from
Hello.What type of gear ratio can I add to my GY6/50cc motor.I know
I can't go to tall in gears.Did pickup a
A9 cam that will work for 50,70,80
cc.Is anyone using a performance
cam in there 50cc?
I am using an a9 cam with my 80 bbkit and works together beautifully. Up hills no problems and straight a way and down hills unbelievably faster compared to a week ago. Had to readjust valves twice a couple days after installation but that's it. Fires right up and idles better than this dudes scooter. Even running a stock carb. Did put aome lighter rollers in it and made one heck of a difference when first taking off and lower acceleration speeds. Was pretty easy for me anyway. Took me 2 hours for everything with the bbkit and 30 minutes for the rollers.
Yours won't be running better than mine did for long with a stock carb on a big bore kit, unless you rejetted it. They came from the factory to run lean, and now with a big bore kit it's only a matter of time till you blow it up unless you rejett or get a bigger 150cc stock carb.
@@Z3CHYD i believe you're absolutely right. Just doesn't seem to have as much top end speed as I thought it would with the bbkit and stock carb. I did just get some jets the guy who sold me the kit but haven't put them on yet. How do you know which one is right for the engine? Reading the spark plug maybe? Thanks z3chyd!
You need to change the roller weights in your variator.
Hey what mount is that for your phone I need one for my bike I can’t see any good ones but yours looks pretty stable
I don't have the link anymore but it was just on Amazon search for motorcycle cell phone mount and it should come up. It mounts using your mirror, and the phone holder part screws tight against your phone so it doesn't fall off
@@Z3CHYD Nice thank you so much brother I really need one.
Did the MPG go way down when you put the big bore kit in? What kind of MPG were you getting before and after, Thanks!
Yea it went down, it got around 100 mpg stock and around 75 mpg with the big bore kit on, which is expected going to a bigger piston, cam, and carb lol
@@Z3CHYD Oh alright, thanks not bad at all. Thanks for letting me know
After 3years can you tell if that 81cc is any good for wheelies and what mods did you put on it
I had it for about 2 years with the big bore kit, and it always ran good for me. With the big bore kit, a9 cam, bigger exhaust, changed the roller weights, a kevlar belt, and a 150cc stock carb it did pretty decent
Wheelies? 🤣 No this is a barebones way to get from point A to B
Yea no wheelies from me, I’ve seen guys do wheelies with the same setup but my clumsy ass wasn’t gonna try lol
whats the engine numbers in the taotao atm5--a1?
so that i get the right kit?
It should be a qmb139
💪🏻

A9 will break your valves. Did it break down?
Nope! She held strong for me for 2 years no issues, as far as I know next owner is still running it too
Whats your top speed now with the big bore?
It wasn't much gained top speed wise, maybe around 40-45, but it was a huge difference in acceleration
what’s the link for this bore kit?
It was just a generic big bore kit off amazon lol
Did you replace any of the bearings or crankshaft?
Nope! Ran like a top no noise
@@Z3CHYD oh thats good, and what speed were you able to cruise at?
@@leonard3655 Normally around 40, and 50ish downhill lol. It would still pull half decent uphills, around 30-35
I have the same moped. Can I swap out the whole engine for a 150cc? Will it bolt up the same?
They will fit but theres some modifications you'll have to do, there's several videos on UA-cam about what other guys did, I know there's a engine/shock mount you have to cut out and move
@@Z3CHYD ok got it. So if I have to cut shock mounts then the answer is no, it does not mount the same.
@@grazz7865 Nope, if it was a bolt on swap, I would've done it to mine for sure! I was looking into it but when I saw there's some fabrication involved I decided not to lol
@@Z3CHYD yeah exactly but it looks like the biggest engine that will easily swap bolt for bolt is an 80cc or a 100cc. Do I have that right? Or are there still modifications that need to made with an 80cc or 100cc?
@@grazz7865 well the 80/100 cc swaps are just big bore kits on the existing engine, so you're just changing out the jug and the piston, which is all the same size, but internally larger. That's why I did the big bore kit, so it still looked factory, and I still had the bike registered as a 50cc scooter. Technically with anything larger than 50cc is considered a motorcycle and you need a motorcycle license, at least in PA
Seems like the new engine is not on its full potential. If I was u you suppose to change out the starter motor to a high torque
Never needed to change to a high torque starter. And I'm not sure what it's full potential is but it was twice as fast as it was stock lol
Just trying to give u an heads up coming from an experience modification mechanic. The stock motor starter has a 2 brush power output high torque has double that
What should I do if I added the 100cc big bore kit and I’m losing speed when I turn the throttle a bit more. It seems to be flooding and I think I should change the jets in it. But I’m not rlly sure what else it could be. It rlly floods bad going up any hills. Any idea what I should do?
Yea if say either change out the jets or try adjusting your carb a little leaner, so it's not dumping so much gas in at full throttle
get the 110cc carb for it. need more fuel for the big bore. also look into giving it more air by taking out the air intake reducer in the air box.
can also get a modified exhaust (big bore exhaust).
Still running good?
Last I know of, I sold it last year
I can tell hes in the Military 2 mins into the video lol
Yep I was in Air Force 6 years lol
@@Z3CHYD haha thank you for your service brother. I was in the Army 3 years from 2014 to 2017
I was 2012-2018, I don't regret a minute of it!
What roller weights do you have in it
Stock roller weights. But I changed the springs to yellow 1500rpm springs and put on a Kevlar belt.
The springs help top speed? I have 7 gram roller weights and i just bought a 150 carb with a 47mm bbk and i can only get to 43 i just want to get to 50 and ill be happy and im stuck.
Justin DeLozier the springs help with acceleration mostly, the roller weights are supposed to held/hinder your top speed, sometimes you have to experiment with them to find the combo that works best in your scooter. Every one reacts different!
Yup. I tried out one of the orange "performance" cdi' s and it made no difference whatsoever. Actually it had weaker spark than the stock cdi lol
What weights did you use in it
I had yellow spring and i forget what size weights I had in the cvt, alot of my stuff I bought from a guy that had it all still in the box, big bore kit was from a company called "Growsun"
@@Z3CHYD I like how you still respond to ?s I don't even have to ask anything..your a great guy very informative and willing to help others learn
@@chrisfishel2962 Thank you very much! I try to respond to any questions to make peoples life easier! If I've figured something out and can help someone I always try to do it!
Whats your MPG like?
With the big bore kit it was around 75 mpg
@@Z3CHYD Wow! Really? What size jets are you using in your carb and what kindof carb?
I forget what jet sizes it had, I was using a stock 100cc carb
How fast does it go??
usually was around 45 tops, I wouldn't want to go any faster on 10 inch rims anyway haha
Mine is a 82 cc as well and it does about 50
What is the top speed?
I’ve gotten it up to 55mph, I wouldn’t want to go any faster on it lol
This Sound you here alot in In the Netherlands Like alot
