No. “Performance CDI’s” are NOT good, they alter the timing in your motor and throw things off causing pre-mature failure a lot of the time. That’s a beginner thing to do, “Blue performance CDI” & crap “Orange performance plug caps” Both not good
No problem man, That’s what I wondered the most when I first started building Scooter’s was the order of things to get the most out of it or to keep it from that functioning properly With different number is the same concept applies on any scoot Motor-trans-gears Topend/bottom end - Intake- exhaust- CVT-gears
@@davidhofinger4927 I have completed everything that you have described. Luckily I have found a good moped mechanic and honest one. i’m happy with the increased acceleration but I definitely want to push it further.
You helped alot. Now rebuilding one I had fro about years. . When I was a kid. It has been parked but in decent condition. And as of yesterday I started restoration project bume bee.
Thank you so much for breaking everything down simply and straight to the point. I loved watching your video and look forward to watch and hear more on how to tune my future bike. With that said please make a lot more. I’m gonna subscribe to you now 👋😆❤️
Everyone I've asked had basically gave me bad reviews on it but i remember my last scooter was a Zuma and it had a blue contra spring in it it got off the line faster and got to top speed quick and that was the only thing done to it so it was a good thing to me not a negative l Like people are saying . But everyone is different is all I can say about that one
@@AudiR8Enthusiats nah eventually it might snap like this one on this bike did but it took a while 3 years to do so And there a dime a dozen and really easy to replace Shit, my 2 strokes cable had to be snipped in half, threaded together and held into one line with a cable tie and it’s solid to this day
You don’t have to as I stated, But if you want the most performance out of your bike upgrading the carburetor throwing in bigger fuel jets with an intake and a pipe is a great route to get the most out of your Big Bore
Love this Series. I have a 2009 50cc Kymco People 2T (Two Stroke) and am looking for ways to extract more performance. Hopefully, this series will continue to serve me well! Thanks!
@@ChristianJordan-d9q no. I gave up but not because I couldn’t find performance parts per se but rather I couldn’t get the damn carbuerator to stop dumping fuel (bought two different ones with the same result) I bought an used 2009 Aprilia SportCity Cube (250Cc) last year and have been pretty happy with it thus far Nevertheless, RacingPlanetUSA is your best chance to locate anything of any value. Good luck!
How much did you invest in these core upgrades alone? Would you recommend going with an older model so you have more money for modifications or do you recommend brand new so everything is in perfect shape? It sounds like you pretty much just keep the frame and replace most internals. Would it be that bad to buy a bike 4-5 years old used if I'm upgrading all this? Really helpful as I'm just playing around with the idea of this but not set yet.
From personal experience from building customers bikes with basically this same treatment, I WONT work on any bike 5+ years old because They do not take well to modifications three or four things always breaks along the way. I had two bikes at once. One of them was a year old the other one was about seven years old. The black one that was only one year old, Flawless build no hiccups. It ran like a champ afterwards. The red bike that was seven years old, How to replace fuses, battery kicker gear in the transmission intake leak and it was a smoke show That somehow ate camshafts literally ate them and disintegrated them over and over again until I put the original stock head back on. It was a mess never again. So yeah, definitely build a brand new bike or at least relatively new you won’t run into 30 different problems Overall, this bike is much more modified now it’s basically fully built down to the suspension tires so many things I spent about $1,100 and this bike is fully built now it’s a much different beast. Look at recent videos definitely worth it.
Half of my parts come from Amazon the other half come from my local Scooter shop but I will start doing so whenever I upload an informational install video,This weekend is one with 1500 pound clutch springs in my transmission 👍
Little bit of prior understanding from cars, google, UA-cam and my local scooter shop. Hands on learning is the best way to learn. Takes time and experience but you have to get your hands dirty to start somewhere 👌
Hi I think I will try with a porting head and a cylinder with 47mm piston. I have never tried it, but looking into my intake and exhaust I can see how rough these gates are from the factory, no petrol mixture / air is happy especially under the valve. My plan is to change my valve head from the short valves of 64mm to long with 69mm. it will give me room to make a small mistake. i just need the small valve arms for 69mm. thanks for your video
oh my god the false information you have makes me shake of fear. 64 or 69mm , no gain at all. they're the same size. and a 69mm valve head is not any better than the 64. its a design thing not a performance thing. you aint gonna get anything going with 69 unless your cyinder have been designed for which is very rare. and it will only fit , not give any performance. you can , instead , go with bigger valve. wont help unless you're at 100+cc on a 50cc base, but it will help when all the most have been done ( and on a 90cc minimum. forget if you're on a 70cc bbk ). its the last thing to do. its true that more air + more fuel = more power. but you cant do more than what the engine allow. try inserting 3l of water in a 1.5l bottle. good luck. the reason we can get a bit more performance going with bigger jet is that from factory they're made for fuel economy and gov nosense crap about pollution. porting your head will in fact help. but you will never feel it not even see it on a dyno. it will help with responsiveness ( very minimal , most people dont even notice it ). but on some engine you're losing instead. those rough edge in fact help with mixture. disturb the flow a bit but help with mixture. mixture is way better than flow. its exactly the same as car. the only difference is in a car you have a big intake. on scooter we have a very small pipe that they call intake pipe. if you want REAL performance and not fake gammick, get a BBK , proper jetting , remove airbox restriction IF you have it ( rare ) and get a GOOD foam filter sheet for it ( like stage6 or really any performance foam filter sheet ) , variator, weights , contra springs and clutch springs. forget about those damn cone filter. they dont give any gain , oftten do worse , and make more noise. we're not honda kid thinking noise equal power. also keep in mind you cannot buy contra spring because you like that brand. a white malossi spring will be the same as a stage 6 green, every brand have different color. also thier stiffness ( percent or rpm ) are based on STOCK engine and transmission. so if you go bbk, forget that "+1500 rpm" or "+15%" thing. you have to play with them.
Had a guy replace my belt it popped for the second time. Had a new carb put on it. It’s now not going fast like it used to to not unless it’s down hill road.
Get a gates powerlink Kevlar belt, make sure it’s seated correctly in the clutch where it sits when Installing it. And yeah That carburetor most likely does not have the same fuel jets as your old one. Does they never come with the same jets that a stock carburetor does If your bike is not modified engine wise, it’s going to be a 72 main jet you can easily use a 74, 76 as well though
@@davidhofinger4927 I’m trying to go as fast as possible. So what ever jet is best. Mine is not modified. I wish it was. It’s the only thing I got to go to work on other than my truck but I don’t have a drivers license yet.
@@bjmccoy5638 I am still currently in the same exact boat and that is why I ride my scooter is every day. I’m waiting to get my license back next year, lord willing. These scooters were too slow for me, especially in certain areas where I live and so I’ve always been a gearhead. I taught myself to modify these things, and they are quite easy to learn very simple machines. If you have a four stroke GY6 bike I can break it down simply for you with the maximum amount of speed that you can achieve from each (modified) displacement sized motor This is the general cap of top speed with each CC heavily modified (fully built) 50cc 39mm piston 45mph 80cc 47mm piston 50mph 90cc 50mm piston 55-57Mph 100cc 52mm piston 55-60mph That’s the 139qmb 50cc generals What you can expect from each size piston in your motor. You have a stock 39mm 50cc piston. (For now lol, IF you even have a GY6 motor let me know what you have) None of this is relevant if you don’t. Besides the “there’s no replacement for displacement” part Keep in mind that that is with a fully built transmission (CVT), Intake system, exhaust & gears. Because, like I said, in this video, there are many different things you can do in each of those things, but that is generally what you can expect mile per hour wise within the “50cc” 139QMB GY6 motor. Without having to swap motors, Only boring the internals of the top end. I hope that makes sense that is just the tip of the iceberg, but that is a very honest general expectation. Keep in mind also that acceleration for any of these things being fully built was going to be significantly faster. That is just the top speed I was talking about. Also, if you are wanting more speed, both an acceleration and TopSpeed big bore kits are a MUST There is no replacement for displacement, truest statement Both from 4 strokes & 2 strokes That speed list does NOT apply to 2 strokes CC’s though but the same concept of “there no replacement for displacement” does
Hi I'll stick to some eco boost mods until my 49 cc Tao top end needs rebuild. Open air box. 90 jet. Good oils. 4.5 g. Rollers and a found. Used 95 mm variator. 40 on the flats. 50 down hill. @ 7900 rpm. I'm 200 lbs. What length belt should I try for the big vari.? 729 is too short For increased shift .plus my gates 729 power link measured 721mm ! Thank you .
I just got a flywing tank 200 cc 2024 for 700. Was brand new but am having bad sputtering problems now and it loses power badly, literally nobody around me in staten island works on them, i cant find anyone. I bought it 40 miles away at a shop i have a warranty at but cant make it back to. I would give anything to find someone who can do these mods for me so my scooter is healthier and stronger and faster
@@DShep-r7g if you’re willing to travel to Monroe Michigan That’s quite a drive I would say a good 10 hours lol My buddy Dave owns the shop here in town, me and him and one other mysterious guy that we both never spoke to knows about Scooters extensively
Give it a few weeks of cruising around town and then venture out too busy roads Don’t use the front break in the rain. Use both brakes at the same time. There’s so much I can say when it comes to modifying these things you’re going to make a mistake but they’re not expensive to fix you’re going to break parts but that’s a part of the process Always use 93 octane, Replace your oil every 2000 miles on the dot. Give it a fresh spark plug every so often. Let your bike warm up for about five minutes every time unless you were just running it and it is already warm. You can ride in the rain just be twice as cautious and stay off of that front brake. There are many things I can say, but that’s what I can think of off of the top of my head
80cc Big bore kit It’s only $56 on Amazon I just bought one for a giveaway I’m going to do for this channel The two biggest differences was when I installed a big bore kit and then the second biggest difference was the Gates powerlink belt A variator is a great upgrade as well, That will increase your throttle response and acceleration but not top speed navigator is only like 25 bucks
I bought a PONY 50 just because of your videos lol I have no experience in mechanic but your videos are very easy to follow. It might be too much to ask but do you have the links for the upgrades your put on from Amazon?
@@c.l8261 when I have some free time, I could do that for you I put on many many many upgrades. I cannot list every single link, but I can at least highlight and find the ones you are looking for.
I just got one of those cheap scooters and it tops out at 38 mph I’m trying to go 45 but I don’t want to change the engine much. I want to change the cvt belt. what belt did you buy and if that won’t do much I can change the pulleys
I just put a 80cc big bore kit big valves and a little bit better cam on my 2016 Wolf Blaze I bought it for 500 from a little ole man that only road it to the store which was only about 3miles round trip. It had 500miles on it when I got it and it looks brand new. It's never been out in the weather. My problem is the stock carburetor mainly it has no adjustments. It absolutely sucks. lol What's the best size for what I have ??? I think you said you have a 20mm on yours. Can it handle a bigger one ??? I've watched a few of your vids. Trying to learn all I can. I subscribed. 👍✌️
Yeah 20 mm carburetor works best with an 80cc Big bore. I’m going to be switching to a PWK flat slide carb next season but the only size that I can get for that is a 21 mm. Gonna have to down jet the main fuel jet. 20’s always the recommended size
I'm looking at a Tao Tao 50 pony (I know... but it's what I can afford) Want to do some mods ie BBC and exhast. Also If I install 5.5 gram roller weights or 7 gram sliders in the CVT What color/size "clutch springs" and "contra spring" should I try first? Thanks in advance to anyone who responds
Yellow 1500 pound springs are usually the go to Contra spring or 1000lb black spring for others Same yellow clutch springs will do it justice But my buddy runs red 2000 pound clutch springs and it’s fantastic if get both yellow and red install them both and test em Seven grand might be too heavy but your bike is different than mine as I had negative results with 7 g rollers but it doesn’t hurt to try the happy place for these Pony50’s are 4.5-7g usually Any of those numbers in between there you just have to try it and see what it does
@@MindKontrolleProject My experience with sliders is if you have a aftermarket variator do not bother using them they really only work in stock variators I just made a review video directly comparing 5g rollers to 5 g sliders, What I found was my top speed was reduced by 7 mph With the sliders only took off a half a second from 0 to 20 and 0-40 But lost the top speed compared to the 5 g rollers Do not recommend getting them especially if you have an aftermarket variator with different ramping done to it already, you Should check out that comparison video I made it about a month ago
Straight up Amazon Still running the same piston to this day. 2 1/2 years later I’ll drop a link for you www.amazon.com/GOOFIT-Cylinder-Replacement-Stroke-Scooter/dp/B0B7BPQ9RW/ref=mp_s_a_1_3?crid=6BO6UZ42YTUA&dib=eyJ2IjoiMSJ9.OCDzCjCxV_bq9C7nl34LWWKYIZPNbbpeDyaAz6gORJMYi71avbdK3NruG91pQuDCh3KRNeZk9M-ZC1kQIZKIahshb4P_-An0qqjn3hW9EUnEZrfrbjgxXIploK-6ntv-XHoEEmDfSS2mX6tR9IIaO05RBmMWUA-cyzwCC8_G75Lp69AW0AqcZHyxlI14gTU_RQlRtQZUAMo1J2zPpQBlcg.XB3uuohJyvFvzKhXYhrYrYbALyOlxA7-BQwZW_PvLxk&dib_tag=se&keywords=139qmb+47mm+big+bore+kit&qid=1714767686&sprefix=139qmb+47mm+big+bore+kit%2Caps%2C314&sr=8-3
Since I don’t have the gy6 motor because I don’t have the “qmb” in my code, should I build a new motor or build the omb granted I don’t really have money to drop on a new motor after buying the bike
No the QMB’s are known to be slow unless you heavily modify them The same recipe follows for any other motor Big bore kit, bigger carb, pod air intake filter, performance exhaust, Kevlar belt. Just with different numbers
TodayI just got a stock 2022 50cc that already does 52 with me on it. and im 6 foot 3 264 pounds 😅😂. Im trying to find out if im just lucky or if there is work done to the scooter. (Slight language barrier from who i got it from) it was so new i peeled alot of the protective plastic off. So i doubt they upgraded it yet. idk😅 Cus i hear alot of people wayyy smaller than me say they only go 30. I was very surprised when i got home
This is a known fact within the Scooter community. I hate to burst your bubble. You can go to many other forums, or the Internet or people within the community personally. But the stock analog speedometers are off, way off It said that I was doing 50 mph one in fact I was only doing 38 There is usually a double digit Difference of what you’re actually doing if you do not believe me ride by a speed trap and compare to what your Scooter is saying, or download a GPS speedometer app and record your speed there compared to what you were speedometer saying I’m sorry to inform you this that is part of the reason which motivated me to upgrade my Scooter to begin with because I actually wanted to do 50 mph lol
@@davidhofinger4927 see now that was definitely a thought to pass my mind. I had the idea to upgrade trying to go about 50. Jumped on it and was going 50 😂 so you could imagine the look on my face. The stock speedometer on this 50 also goes all the way up to 90MPH 😭😭 Either way thank you for the reply brother. Ive owned two or three crf 70s but they dont have speedometers it was always just a guess to me.
@@nastynockinsonofficial9023 I recommend using a GPS app that is free. The one I use specifically is simply called “Speedometer” And it will tell you your actual speed down to the decimal points for free. It’s really useful for testing and tuning. Want to find out what you’re doing you’re gonna find that motivation to beef it up lol No problem man

Did look for a similar 125/150 too to just slap the registration plate on from the 50 to get 50cc insurance. 125cc insurance here is like 5x as expensive. And insurance here is mandatory.
@@Ritzacracka in my state in America, the law in Michigan states “90cc and under needs no insurance or license to operate legally” 125cc or just 90cc and up License, tag, registration & insurance required. SO for dirt ass cheap I can highly modify my bikes all the way up past 90 without knowing because my title and registration sticker says it is a “50cc” Because that is what they started out as, especially my two stroke, which hits past 60 and beats modified 150 4 strokes if that says anything For nothing. It’s all a facade for the law but it holds up in court
Hey David. Love your videos, just picked up a TaoTao50 for 200 bucks. Do you have a complete list of the brands/parts you used? Not expecting you to link them all, just the names if you had a minute.
Here’s a list of every single modification that I have done to this bike after this point I made even more upgrades to where it is fully built now I believe it is in the description of the video I know it is you should check it out everything is there keep going man with another 800 bucks you could have a fully built bike yourself good bang for cheap bucks 👌
No, not all motors have the same numbers, but you can always find it in the same place, On the bottom of the block underneath the transmission case where it is located
Not the same displacement and carburetor numbers but the same concept yes Big bore kit Bigger carb Bigger fuel jets Intake filter Exhaust/pipe Kevlar belt
@@pouliotzacharie2358 depends where you live but really their not gonna know anyways 🤷♂️ but definitely stick with the stock air box with a stock 50cc 2t 18-19mm carburetor is best for that set up don’t blow your motor with a pod filter on a stock 2t bike like I did
Literally amazon lol the belt I got from there but the internal parts I got from online/my scooter shop if you know exactly what your looking for you will find it cheap + legit on amazon
Amazon is where I’ve purchased 70% of my aftermarket performance parts that my local shop didn’t have in stock. Search your engine and transmission number following it with the parts you want and you’ll find them there. For example “Gy6 139qmb 1500 contra spring” you should be able to find what you need

Amazon will be your best friend, add “139qmb 50cc” before any part your looking for and you’ll find a list of aftermarket items, Amazon’s full of em name brand and not

I called it a moped for this videos title, because I wanted to attract newcomers. I specifically titled it incorrectly a moped, so that new people would find this video.
why would you gain topspeed with a different belt? that makes absolutley no sense because there the torque is the lowest. If your belt would slip, then it would be a strict torque thing - meaning it affects acceleration. So that is just not true. Maybe you put different weights in at the same time and thought its because of the belt. These work like a gear ratio - meaning that lighter weights will give you more acceleration but also less topspeed.
No maaan it’d slip where torque where was the highest point It 120% picked up ALOT of top speed from my own story’s plus countless others It just a positive thing to do for your bike for acceleration AND (depending on what’s done to your motor) Top speed
I have no idea what youre trying to say at the beginning... Well yes youre right regarding acceleration, but not with topspeed. Topspeed is about gearing, rpm and power - not torque
Know what kind of bike yours is, what brand so for example Taotao Pony50 Know what size motor you have 50cc Know what KIND of motor/trans it is Example 139qmb GY6 You can look up what kind of motor and transmission your bike has online and you will find it and whatever modification you were looking for you were going to attach that with it for example Performance exhaust 139qmb GY6 And you would find what your looking for

The red bike that was seven years old, How to replace fuses, battery kicker gear in the transmission intake leak and it was a smoke show That somehow ate camshafts literally ate them and disintegrated them over and over again until I put the original stock head back on. It was a mess never again.
So yeah, definitely build a brand new bike or at least relatively new you won’t run into 30 different problems
Overall, this bike is much more modified now it’s basically fully built down to the suspension tires so many things I spent about $1,100 and this bike is fully built now it’s a much different beast. Look at recent videos definitely worth it.
You should provide links for your products you're listing, you could even make commons from Amazon when people use your links to buy
Half of my parts come from Amazon the other half come from my local Scooter shop but I will start doing so whenever I upload an informational install video,This weekend is one with 1500 pound clutch springs in my transmission 👍
I stilll have no idea what im doin how do i know where goes where , it takes time im , but hey how did you learn , how you got your knowledge?
Little bit of prior understanding from cars, google, UA-cam and my local scooter shop. Hands on learning is the best way to learn. Takes time and experience but you have to get your hands dirty to start somewhere 👌
Perfectly explained 😎
Hi I think I will try with a porting head and a cylinder with 47mm piston. I have never tried it, but looking into my intake and exhaust I can see how rough these gates are from the factory, no petrol mixture / air is happy especially under the valve. My plan is to change my valve head from the short valves of 64mm to long with 69mm. it will give me room to make a small mistake. i just need the small valve arms for 69mm. thanks for your video
oh my god the false information you have makes me shake of fear.
64 or 69mm , no gain at all. they're the same size. and a 69mm valve head is not any better than the 64. its a design thing not a performance thing.
you aint gonna get anything going with 69 unless your cyinder have been designed for which is very rare. and it will only fit , not give any performance.
you can , instead , go with bigger valve. wont help unless you're at 100+cc on a 50cc base, but it will help when all the most have been done ( and on a 90cc minimum. forget if you're on a 70cc bbk ). its the last thing to do. its true that more air + more fuel = more power. but you cant do more than what the engine allow. try inserting 3l of water in a 1.5l bottle. good luck.
the reason we can get a bit more performance going with bigger jet is that from factory they're made for fuel economy and gov nosense crap about pollution.
porting your head will in fact help. but you will never feel it not even see it on a dyno. it will help with responsiveness ( very minimal , most people dont even notice it ). but on some engine you're losing instead. those rough edge in fact help with mixture. disturb the flow a bit but help with mixture. mixture is way better than flow. its exactly the same as car. the only difference is in a car you have a big intake. on scooter we have a very small pipe that they call intake pipe.
if you want REAL performance and not fake gammick, get a BBK , proper jetting , remove airbox restriction IF you have it ( rare ) and get a GOOD foam filter sheet for it ( like stage6 or really any performance foam filter sheet ) , variator, weights , contra springs and clutch springs.
forget about those damn cone filter. they dont give any gain , oftten do worse , and make more noise. we're not honda kid thinking noise equal power.
also keep in mind you cannot buy contra spring because you like that brand. a white malossi spring will be the same as a stage 6 green, every brand have different color. also thier stiffness ( percent or rpm ) are based on STOCK engine and transmission. so if you go bbk, forget that "+1500 rpm" or "+15%" thing. you have to play with them.
Thanks bro it was really helpful
Np I’m glad I could help
now this is a good tutorial
I've got a 2 stroke benelli 49x should I do this or is it any different for a 2 stroke?
Same concept, different numbers
Yessir, you can watch my videos on my 2 stroke build doing the same things just with better parts
Very informative appreciated video
No problem man I’m glad I could help that’s why I made this video it makes me feel good that it is doing what I intended
Had a guy replace my belt it popped for the second time. Had a new carb put on it. It’s now not going fast like it used to to not unless it’s down hill road.
Get a gates powerlink Kevlar belt, make sure it’s seated correctly in the clutch where it sits when Installing it.
And yeah That carburetor most likely does not have the same fuel jets as your old one. Does they never come with the same jets that a stock carburetor does
If your bike is not modified engine wise, it’s going to be a 72 main jet you can easily use a 74, 76 as well though
@@davidhofinger4927 I’m trying to go as fast as possible. So what ever jet is best. Mine is not modified. I wish it was. It’s the only thing I got to go to work on other than my truck but I don’t have a drivers license yet.
@@bjmccoy5638 I am still currently in the same exact boat and that is why I ride my scooter is every day.
I’m waiting to get my license back next year, lord willing.
These scooters were too slow for me, especially in certain areas where I live and so I’ve always been a gearhead. I taught myself to modify these things, and they are quite easy to learn very simple machines.
If you have a four stroke GY6 bike
I can break it down simply for you with the maximum amount of speed that you can achieve from each (modified) displacement sized motor
This is the general cap of top speed with each CC heavily modified (fully built)
50cc 39mm piston 45mph
80cc 47mm piston 50mph
90cc 50mm piston 55-57Mph
100cc 52mm piston 55-60mph
That’s the 139qmb 50cc generals
What you can expect from each size piston in your motor.
You have a stock 39mm 50cc piston.
(For now lol, IF you even have a GY6 motor let me know what you have)
None of this is relevant if you don’t.
Besides the “there’s no replacement for displacement” part
Keep in mind that that is with a fully built transmission (CVT), Intake system, exhaust & gears.
Because, like I said, in this video, there are many different things you can do in each of those things, but that is generally what you can expect mile per hour wise within the “50cc” 139QMB GY6 motor.
Without having to swap motors, Only boring the internals of the top end.
I hope that makes sense that is just the tip of the iceberg, but that is a very honest general expectation.
Keep in mind also that acceleration for any of these things being fully built was going to be significantly faster. That is just the top speed I was talking about.
Also, if you are wanting more speed, both an acceleration and TopSpeed big bore kits are a MUST
There is no replacement for displacement, truest statement
Both from 4 strokes & 2 strokes
That speed list does NOT apply to 2 strokes CC’s though but the same concept of “there no replacement for displacement” does
@@davidhofinger4927 illl be in touch. Bare with me.
Hi I'll stick to some eco boost mods until my 49 cc Tao top end needs rebuild. Open air box. 90 jet. Good oils. 4.5 g. Rollers and a found. Used 95 mm variator. 40 on the flats. 50 down hill. @ 7900 rpm. I'm 200 lbs.

Just saw your vid for the first time. Many thanks. Tuning vid? Hells yea.
I just got a flywing tank 200 cc 2024 for 700. Was brand new but am having bad sputtering problems now and it loses power badly, literally nobody around me in staten island works on them, i cant find anyone. I bought it 40 miles away at a shop i have a warranty at but cant make it back to.
I would give anything to find someone who can do these mods for me so my scooter is healthier and stronger and faster

Thank you, I hope it helped you out 👌
Any tips for new moped riders ?
Give it a few weeks of cruising around town and then venture out too busy roads
Don’t use the front break in the rain. Use both brakes at the same time.
There’s so much I can say when it comes to modifying these things you’re going to make a mistake but they’re not expensive to fix you’re going to break parts but that’s a part of the process
Always use 93 octane, Replace your oil every 2000 miles on the dot.
Give it a fresh spark plug every so often. Let your bike warm up for about five minutes every time unless you were just running it and it is already warm.
You can ride in the rain just be twice as cautious and stay off of that front brake.
There are many things I can say, but that’s what I can think of off of the top of my head
what do you think is the best cheap upgrade?
80cc Big bore kit
It’s only $56 on Amazon I just bought one for a giveaway I’m going to do for this channel
The two biggest differences was when I installed a big bore kit and then the second biggest difference was the Gates powerlink belt
A variator is a great upgrade as well, That will increase your throttle response and acceleration but not top speed navigator is only like 25 bucks
I bought a PONY 50 just because of your videos lol I have no experience in mechanic but your videos are very easy to follow. It might be too much to ask but do you have the links for the upgrades your put on from Amazon?
@@c.l8261 when I have some free time, I could do that for you I put on many many many upgrades. I cannot list every single link, but I can at least highlight and find the ones you are looking for.

@@c.l8261 so what parts are you looking for? Let me know and I will give you a list of links.

@@c.l8261 I got you, I just got to work, but I’ll have some downtime later today and I will send you those links. I won’t forget.
I just got one of those cheap scooters and it tops out at 38 mph I’m trying to go 45 but I don’t want to change the engine much. I want to change the cvt belt. what belt did you buy and if that won’t do much I can change the pulleys
Where can I get that exhaust? I've been looking for one but not confident on buying one and being sure it will fit
Amazon. Type in “139qmb Gy6 50cc exhaust” and any one of those will bolt right up to your head 👍
I just put a 80cc big bore kit big valves and a little bit better cam on my 2016 Wolf Blaze I bought it for 500 from a little ole man that only road it to the store which was only about 3miles round trip. It had 500miles on it when I got it and it looks brand new. It's never been out in the weather. My problem is the stock carburetor mainly it has no adjustments. It absolutely sucks. lol What's the best size for what I have ??? I think you said you have a 20mm on yours. Can it handle a bigger one ??? I've watched a few of your vids. Trying to learn all I can. I subscribed. 👍✌️
Yeah 20 mm carburetor works best with an 80cc Big bore. I’m going to be switching to a PWK flat slide carb next season but the only size that I can get for that is a 21 mm. Gonna have to down jet the main fuel jet. 20’s always the recommended size
@@davidhofinger4927 Cool . Thanks for the reply. ✌️
I'm looking at a Tao Tao 50 pony (I know... but it's what I can afford)
Want to do some mods ie BBC and exhast.
Also
If I install 5.5 gram roller weights or 7 gram sliders in the CVT
What color/size "clutch springs" and "contra spring" should I try first?
Thanks in advance to anyone who responds
Yellow 1500 pound springs are usually the go to Contra spring or 1000lb black spring for others
Same yellow clutch springs will do it justice But my buddy runs red 2000 pound clutch springs and it’s fantastic if get both yellow and red install them both and test em
Seven grand might be too heavy but your bike is different than mine as I had negative results with 7 g rollers but it doesn’t hurt to try the happy place for these Pony50’s are 4.5-7g usually Any of those numbers in between there you just have to try it and see what it does
@@davidhofinger4927 Thanks👍 the 7g was for "sliders", I heard you go up 1 g from "rollers". Not sure if that is correct. Thanks again
@@MindKontrolleProject My experience with sliders is if you have a aftermarket variator do not bother using them they really only work in stock variators
I just made a review video directly comparing 5g rollers to 5 g sliders, What I found was my top speed was reduced by 7 mph With the sliders only took off a half a second from 0 to 20 and 0-40 But lost the top speed compared to the 5 g rollers
Do not recommend getting them especially if you have an aftermarket variator with different ramping done to it already, you Should check out that comparison video I made it about a month ago
Where did you get your big board kit
Straight up Amazon
Still running the same piston to this day. 2 1/2 years later
I’ll drop a link for you

Since I don’t have the gy6 motor because I don’t have the “qmb” in my code, should I build a new motor or build the omb granted I don’t really have money to drop on a new motor after buying the bike
No the QMB’s are known to be slow unless you heavily modify them
The same recipe follows for any other motor
Big bore kit, bigger carb, pod air intake filter, performance exhaust, Kevlar belt.
Just with different numbers
TodayI just got a stock 2022 50cc that already does 52 with me on it. and im 6 foot 3 264 pounds 😅😂. Im trying to find out if im just lucky or if there is work done to the scooter. (Slight language barrier from who i got it from) it was so new i peeled alot of the protective plastic off. So i doubt they upgraded it yet. idk😅 Cus i hear alot of people wayyy smaller than me say they only go 30. I was very surprised when i got home
This is a known fact within the Scooter community. I hate to burst your bubble. You can go to many other forums, or the Internet or people within the community personally.
But the stock analog speedometers are off, way off
It said that I was doing 50 mph one in fact I was only doing 38
There is usually a double digit Difference of what you’re actually doing if you do not believe me ride by a speed trap and compare to what your Scooter is saying, or download a GPS speedometer app and record your speed there compared to what you were speedometer saying
I’m sorry to inform you this that is part of the reason which motivated me to upgrade my Scooter to begin with because I actually wanted to do 50 mph lol
@@davidhofinger4927 see now that was definitely a thought to pass my mind. I had the idea to upgrade trying to go about 50. Jumped on it and was going 50 😂 so you could imagine the look on my face.
The stock speedometer on this 50 also goes all the way up to 90MPH 😭😭
Either way thank you for the reply brother. Ive owned two or three crf 70s but they dont have speedometers it was always just a guess to me.
@@nastynockinsonofficial9023 I recommend using a GPS app that is free. The one I use specifically is simply called “Speedometer”

“90cc and under needs no insurance or license to operate legally”
125cc or just 90cc and up

I can highly modify my bikes all the way up past 90 without knowing because my title and registration sticker says it is a “50cc”
Because that is what they started out as, especially my two stroke, which hits past 60 and beats modified 150 4 strokes if that says anything
For nothing.

😅😂🤣🤣
why would you gain topspeed with a different belt? that makes absolutley no sense because there the torque is the lowest. If your belt would slip, then it would be a strict torque thing - meaning it affects acceleration. So that is just not true. Maybe you put different weights in at the same time and thought its because of the belt. These work like a gear ratio - meaning that lighter weights will give you more acceleration but also less topspeed.
No maaan it’d slip where torque where was the highest point
It 120% picked up ALOT of top speed from my own story’s plus countless others
It just a positive thing to do for your bike for acceleration AND (depending on what’s done to your motor)
Top speed
I have no idea what youre trying to say at the beginning...
Well yes youre right regarding acceleration, but not with topspeed. Topspeed is about gearing, rpm and power - not torque
remove spacer
Never needed too, it never restricted anything
Can you make a video. For how to figure out what size piece you need for a mod?/repair?
Know what kind of bike yours is, what brand so for example
Taotao Pony50
Know what size motor you have
50cc
Know what KIND of motor/trans it is
Example
139qmb GY6
You can look up what kind of motor and transmission your bike has online and you will find it and whatever modification you were looking for you were going to attach that with it for example
Performance exhaust 139qmb GY6
And you would find what your looking for
Okay. Sounds good, and it's just a saga 2009 50cc moped thank you too though
@@EDTlives Look on the side of the motor right above the transmission and it’ll always have like a numerical code that tells you what kind of bike it is
