Speed testing in the rain! Your a madman sir doing gods work for the scooter army props.
Throwing some 3 grams in then you can pop wheelies
Not that easy lmao
I just left two standard weight rollers on the table and left 4 in place. Works just fine and for free :D
You are smart , be easy on yourself !! Best video I seen yet on detail and I know you know what your taking bout
Great video, thanks! One of the better videos on this subject.
Use sliders instead of rollers and you will gain both acceleration and top speed. Also, to tune your transmission accurately, you need a tach. They are not that expensive and you can see your launch speed (Mine is 5200 rpm) and top end rpm. (mine is 8,500.) I run a stock 49cc with a cone air filter and glass pack muffler for which I had to rejet the carb. to 32 pilot and 85 main. (You have to do plug chops to make sure you are not running too lean when you swap out the stock muffler and air box and this takes some trial and error but...you can narrow it down by reading what someone else with your engine has done.) I am running a yellow torque spring in my clutch and 6.5 gram sliders. I accelerate really well now and hit 43 mph on the gps for top end. It will go faster if I let it but I do not want to go over 8,500 rpm as my engine has 6,000 miles on it and...it was made in China. I could go a little heavier on the sliders but, this is fast enough on those little tires.
That's great advice. Thank you.
@@LabCoatPaul You are welcome. I learned all of this over at 49cc scoot dot com where there are tons of good folks that help others and...they publish manuals and how to's for fixing our scoots. I have always owned motorcycles but a guy gave me this scooter about 45 years ago and I have replaced or repaired just about everything except the engine, ha ha. Your video was very well done and very clear. Oh, I also bought a $13 little tool that has 3 teeth that locks the variator for removal/installation and it bolts on using 2 of the cover screws and holes and engages the teeth on the pulley. Best idea I have seen and it works well.
Nice I may use your formula ! 85 jet Free flow air. Yellow spring. Sliders. 43 on the flat. On my 50cc. Bill
49 cc scooter did pressure. Spec tests on stock blue yellow. And red clutch springs. They were not. Consistent at all. Bill
no substitute for cc's. air filter, aftermarket, 70cc head, a9 cam, open pipe, #95 main jet.40 psi tires. hold on to your handle bars.
I was happy with my Adly Jet 50 that I bought used. However we pushed it pretty hard on some two up trips and now it seems stuck in high gear with less than 3,000 miles on it. Going to have to dig in and see if I can get it back to where it was, good acceleration and 43 mph top speed. Looks stock to me.
Quicker. Not faster. You mentioned the mph wasn't accurate but im super curious what happened to the top speed?
top speed test??
Hello,After putting the new carb,went back and drill out the cap,very slow.Just to find they had the idle mixture screw turn all the way in.So I've been riding around with the motor running in very lean state?I took off the cap and looked at the belt,took off the Variator and check the roller.2-5.1 and 4-5.0.Got myself a scale to check them.Added my new rollers 5.5 grams,and put the cap back and forget to tighten the nuts,my stuff is on the way to fix that.
For this scooter I suggest 4.25 or 4.3g rollers.
@@stuwest3653 if you mean that this scooter with 6.5 g rollers and kid on it with 45 kilos go well you are wrong.
Looks like 6g rollers are the best and perfect medium for all around performance.
GOOD VIDEO AND EXPLANATION. THANKS FOR SHARING!👍
You can buy a high performance clutch with those springs in them for 40.00 dollars and save a little money...
if you can buy a piaggio zip 50 scooter they can go 45mph and that's as standard .. i bought a second hand one its a 2006 sp model and its so fast .. i read up about the zip 50 models and they are fast as standard so try and buy one you'll see
File down the belt teeth or buy a malossi belt, it’s wider and the teeth are shallower so the belt will go to a lower gearing from stationery and go all the way to the max of your variator
I mean if you could get some mods like
-a performance exhaust (ones that would pass certain decibel limits)
-a slightly bigger carburetor
*a 20mm carb would be great
-a spare cylinder head which *you'll enlarge the ports
*install a performance camshaft
*install bigger valves
-CVT Tuning Kit
-Taller Final Drive Kit
I mean if you could bump the hp's up to 7hp or more that would be great for speed 🤷🏻♂️
I think trying to make a 50cc scooter fast is pointless. Stock they're about 2 hp, and it would take a lot of work and money to get it up to 7hp.
You could simply switch the scooter out for a 150, that comes with 9hp stock.
My 50 cc moped was slow but I drilled 2 holes in muffler and now it is running 70-75km
thanks Paul. I've pulled mine apart many times but still experimenting. what weight(or color) springs do you have in the rear clutch? I have three clutches each with blue, yellow, and red springs and weights from 4.5 to 9 grams. the bike is 100cc now after 2nd bbk. current setup is 8g front and yellow springs rear. my best speed so far is 53mph(when I have enough road) on level ground but dies on hills. thinking of turbo, supercharger, nitrous, octane booster, etc. just kidding, but I would like to keep up with traffic and make lights rather than try to catch up. thanks again. Mike
Get a new CDI for the ignition
And a new larger carburetor, snd decide what you want, great hole shots & wheelies, or more top speed to keep up with traffic, one does not exclude the other, but you will spend lots $$, to have both, most scoots have enough acceleration from a stop to keep up with other traffic, and not be holding up traffic behind them
But top speed went 💩
Heavier rollers equal more top speed but 💩 acceleration.. light rollers 💩 top end but good acceleration
💩 👍🏿
So 5.5 grams is the best??? for start and final speed acceleration ???
He got the best out of 5g I believe
@@motorcyclerescuer I already tuned my scooter.. got all new variator multivar 2000 with 7.0grams, white big spring , white small springs, malossi fly clutch and bando vs belt (orginal) now i got better start middle and final speed.. max speed is 100kmh.. on downhill can do 105-110... 😃😃
@@KikoBach94 nice, I'm a mechanic on my channel but never really look at variator tuning. I may try it on my channel at some point.
@@motorcyclerescuer I thought the heavier the better?
@@BTBC9870 no not necessarily. You need to hit the sweet spot with the weight. Too light and you lose power, too heavy and you lose power. Slightly lighter can help with acceleration but may skim a little of the top end. Slightly heavier and it may have a better top speed but be slower to accelerate.
Are you heavyer rollers better speed
What should I understand from this video. (I do not know your language)
light cylinders?
heavy rollers?
I have a scooter upgraded from 50cc to 80cc
Hi I have a Lexmoto Echo what you recommended to fix on this scooter to go more faster Thks
I have a 125 gy6 with 12g roller weights with minor flat spots after +17k kilometres I will replace with heavier 13g roller weights because I am looking for a less revy engine and more mpg am I going in the right direction
I have a Taotao thunder It can reach a speed of 45.....2017.
What have you done to it? I have a 2015 Zummer with UNI pod filter, 90 main jet, and 34 idle jet and it also reaches about that speed. I'm just looking to tune the transmission a little to make sure i'm utilizing the full gear range.
no spring change just rollers and you want benefits
cool
i have a suzuki ADDRESS 113CC goes really well do i buy rollers for that particular scooter and what weight would improve it a bit thanks
My moped is at too low of rpm while accelerating would lighter rollers help
Yes. Lighter rollers will keep the engine at higher RPM.
@@LabCoatPaul thank you 👍
Hi I’m after tool for release variator but have Piagio zip 50 cc

I'm looking to buy a new 49cc scooter Tao Tao Pony 50 :)
Looking for (simple plug n play) type mods.
I want to keep it simple and get a little more high end performance.
Can I just replace the stock carb and muffler system and still be reliable?
Looking at:

What do you folks think?
Well when you enter the red on the speedometer that's when you blow up your engine have a good day
Hey Paul. I got a scooter just like this one. However I did not get any papers with it and belt was gone of the scooter. Can you please tell me size of the belt on your scooter. It would really help me a lot. Thank you very much.
You can see it at 2:10 in the video. It's 723 x 18 x 30 Also check out this video: th-cam.com/video/xh37xm0fWmY/w-d-xo.html
hi .. so i hope i dont bother anyone but .. i recently bought an awsome Motowell Darox 50cc 4 stroke EFI continental scooter , front and rear disk breaks , full front and back LED lights / signals , digital dashboard ... its beautyful but .. if i wanna mount an 80cc engine kitt on it ... what modifications do i need to make on it ?? and ... is the malossi 80cc aluminium kitt reliable ? i mean does it go 15-20.000 kms range ? thx :)

Nice info bro👍👍
Question: I'm buying a scooter, and the seller says the exhaust and variator have been upgraded. Is this something I should worry about? I'd like to avoid any 'hacky' or experimental modifications, but if upgrading the variator is standard practice, I'll probably buy it.
Changing the variator and roller weights requires some experimentation and tuning to find the ones that work the best. If you don't want to do all that work, spend a bit more and buy a complete transmission kit.
@@LabCoatPaul Thanks, the modifications are already done, I just have to decide if I want the scooter or not. I'm not mechanically inclined, so I wouldn't know how to change it back (or replace the transmission).
anyone know whats the best weight to use for rollers when your carrying a pillion? 125cc about a combined weight of around 120kg's
Hi, I have taken off many variatiors, Im tryn to get the variator off of my prescott 50i gy6 and the nut will not come off, I tried my usual torque wrench that always works and my buddy came by with large set of socket wrench and he couldnt do it, have you had a situation where you cant get the variator off and what did you do? Id hate to not be able to upgrade this scooter TY again!!!
Have you tried using an air powered impact wrench? You could also heat the nut with a torch.
@@LabCoatPaul No, just my makita electric one, but its worked everytime, I should heat the nut you said?
@@thedaydreamer7972 pneumatic impact wrenches are 10x more powerful than electric ones. Heating the nut can help.
Hi Paul can you please tell me is it possible to use 5Gr on NECO GPX50
What would be a suggested roller weight for GY6 50cc with a 173lbs person be? Looking for quicker acceleration.
Take your rollers out. Weigh them. Try some lighter rollers.
I weigh about 225 and I have a 50cc 4 stroke. What size rollers do you think will give me decent take off and about 40 mph top speed
The exact weight depends on your scooter, but generally lighter weight rollers will let the engine rev up higher. You can also get better take off by getting higher RPM clutch springs. That's the 3 little springs in the clutch.
Hi Paul can you help me please I have a Piaggio MP3 500 LT 2014 the engine was damaged so I bought another engine but the 3 wire connector from the stator is different, from both engines the 3 wires are all black and from the connector to the voltage regulator the 3 wires are all yellow
Do I need to strip the engines and change the stator or can I cut the wires and join to the different connector, will it matter if the wires are connected wrong
Thanks Bill
It seems like the 3 wires probably do the same thing, so it's ok to just connect them. Stators usually have 3 wires output to the regulator. These wires carry alternating current (AC), which is then converted to direct current (DC) in the rectifier. Then the electricity goes to the voltage regulator, which makes sure you have the right battery voltage all the time.
It may be worth removing the flywheel so you can look at the stator, and you might as well grab that old stator so you have a spare. Then you'll know if the stators are different, and you'll know for sure what the wires do. Also, if the 3 wires are AC output from the stator, it doesn't matter which position each one is connected to.
I have no experience working on Piaggio charging systems, but I have this detailed video about a Chinese scooter that explains all the parts of the charging system: th-cam.com/video/e2fL5DOSK-w/w-d-xo.html
@@LabCoatPaul hi thank you for your quick answer its a pig of a job to get to the stator so i will try to join the wires in the same order in the conections thanks again Bill
My scooter ha hazitation when i stat moving from 0_30 but after the 30 it start to go fast and accelerate hard
Some lighter variator rollers might help. You might also need to tune the carburetor: th-cam.com/video/iCGjVRyN6YU/w-d-xo.html
hey man
thanks alot!!!!!
How to make scooter shift faster? Mine got power only after 10 meters
It sounds like you want your RPMs to be higher and you want your scooter to shift later. That would mean lighter rollers.
@@LabCoatPaul No, I want my scooter to take off immediatly when I press gas. My rollers are allready 4.5 gram
@@RedzicAnel It sounds like you need to tune your carburetor. You may have the wrong air / fuel mixture just off idle. Check out this video: th-cam.com/video/iCGjVRyN6YU/w-d-xo.html
I think you should go for higher weight if that's your preference
How can I get better hill climbing out of my 50cc scooter?
lighter roller will encourage the cvt to stay in low gear ratio so that's your best bet. also better clutch
6 gram rollers 128,9 elapsed time?!!!
Is it correct?
The only number you should pay attention to in this video is the 0-30mph time.
The app picked up sudden handlebar movements as 45mph speed, which I never hit, and the elapsed time was a random number based on when I stopped recording.
I'm sure u know but you don't have to take off your kickstarter.
The higher the variator weight the slower the acceleration is but the top speed is higher
where did you get the phone holder?
It's this one: amzn.to/3nGDXxf
I gotta 50cc....80cc big bore kit....10,000rpm at 40mph top speed GPS...I want to lower the RPMs and keep or exceed the top speed abit...what should I do to the weights?
That's a good question.
Did you install the 80cc big bore kit, and did you modify the transmission?
Scooters usually come stock with medium to heavy rollers, that shift early, keeping the RPM's low. If you have high performance stuff on your scooter, you probably have light weight rollers that keep your RPM's high.
If your rollers are too light, you might rev out the engine too early, and have the CVT never shift to the highest gear.
It sounds like you need heavier rollers.
@@LabCoatPaul bone stock peace sports 50cc that I did the 80cc kit on...I haven't touched the cvt yet....from all the test rides me and my kids have done it behaves near perfect.
@@audiwankenobi361 You can increase the top speed by getting a performance CVT kit. They're about $180, and you get all the CVT parts. Here's an example: www.partsforscooters.com/169-197_QMB139_Transmission-Kit?sc=34&category=132703
Why did the top speed decrease?
Because it's not making the engine more power. It's only allowing the engine to speed up faster. But the rims limit the top speed. So if you make the rpm limit arrive quicker, you don't allow the bike to get up to the same speed. It's a trade off. Id like to know what the actual top speed dropped to because he mentioned the mph on the app wasn't accurate.
You are the best
In gearless scooters, Should we apply grease on rollers and roller-grooves in variator for smooth spinning of rollers in variator?
Or will it make more issues after some time like dust deposit, vibrations etc ? Please tell what should we do with proper reason.
Do not add grease. You want to keep them as clean as possible
@@Sidg2 Do not add grease. As the belt wears, you get a lot of dust in the CVT case and it will stick to the grease and prevent the rollers from moving properly. Also, if you add a lot of grease, it can get on the belt and cause it to slip. This will heat everything up and damage your belt and drive face.
@@LabCoatPaul Is this theory correct that after applying grease on round rollers they don't able to roll properly and tends to slide which cause irregular flat sides. And these irregular flat sides causes vibrations on certain speed? Is it right?
@@Sidg2 I haven't tried putting grease on the rollers, so I don't know for sure what would happen. Here's what I think:
This system is designed to be operated without grease. Adding grease would change how quickly the rollers move. They could behave as a different weight variator rollers and cause your transmission to shift ratios at a different RPM.
Also, because the grease attracts dirt, your shift point would change over time. Even if you tuned your CVT with the best roller weights, you would lose the tune after a while.
You can feel flat spots in the variator rollers when you ride the scooter. Instead of smoothly accelerating, the scooter will almost feel like it shifted gears, and the engine rpm will change quickly just like in a car with an automatic transmission.
A roller with a flat spot will start rolling, then get stuck until you hit a high enough rpm for the centrifugal force to move it through the flat spot, so you get that sudden jump in gear ratio.
@@LabCoatPaul Thank you for your detailed answer. This is the best answer I get.
I have a 110cc scooter (2 years old and 11300 kms total run) and rollers was never changed. Now it have few flat spots. I think vibrations are coming from Variator Rollers.
I feel lot of vibrations at speed of 35 to 45 km/h speed. Vibrations increase with pillion ridder. What's the reason you think about vibrations at certain speed range like 35-45 km/h ?
Super.
So 5.0 g rollers ? Gotcha !!!
I been playing with roller weights I found 10gram is my perfect speed and hill climb. im about 200lbs on a 50cc taotao. Adding weight is easy with epoxy and small nuts.
10gram on a 50cc? must have slow take off. 50cc roller weights should vary from 4g - 8g any higher is for a 150cc usually.
Hi haven't you listened to anything?
You're really worried about 2-3 seconds difference?
Racing mode huh?
Sometimes when you have impatient drivers behind you, it makes a difference. Going 29ish in a 30 would kind of nudge some people. Or if you have to cross an intersections or any of the like, that 2-3 sec counts with oncoming traffic, and traffic behind you.
@@techjunkie3916 :
That's where alert comes in.
Never assume that other vehicle is not a threat.
The faster they are going reduces your time.
Vigilance is the only possible solution.
@@TahoeJones I never argued that point.I also never said no vehicle is a threat. I said yes it does make a difference.
@@techjunkie3916 50cc scooters are soooooooo slow! You need to squeeze every bit of speed you can so you don't get run over.
@@LabCoatPaul I didn't challenge that point. I said yes if you have impatient driver's behind you.
Could i go with 2.8 grams?
you will have little low end torque so don't try hills or carry a pillion.
30 second 0-50kmh 😂wow
Sheesh, everyone says it's not needed cause it's not sealed. Makes sense that something that thin is what would seize the bendix.
The scooter is garbage right out of the box,spend the extra money and invest in a Yamaha
Hello u just pick up 50cc tao tao how can I make it faster?do I have to buy them rollers n what size please
Will changing my variator weights to lighter ones affect the fuel consumption?
Yes, fuel economy will be worse
I have a 50cc Gy6 and the CVT has a bushing on the case cover that is supposed to support the bendix. I had done some vatiator tuning that made electric starting non-operational and discovered the bendix to be the issue. After changing two bendix gears, replacing the bushings on both sides as well, I found there to be a spacing issue causing the bendix to be "pinched" when closing the case. I tried different combinations of loosened and tightened bolts on the cover and found that in order for the bendix to operate enough to start I would have to loosen all of the cover bolts. After riding a short distance (perhaps 2- 2.5 miles round trip) I found that standard riding conditions would rattle the bolts loose and the cover may come off entirely. To adjust I put some washers between the case cover and the mounted portion of the CVT and ran the same bolts through them, allowing me to tighten them enough into place. Because I didn't have washers between all of them, I cracked a small portion of the cover completely off by over tightening one of the bolts. Can you please cover bendix issues more thoroughly? I saw your other video on cleaning it but I think my scenario may be something that could arise with a few people. If there was a t.v. show for scoots you'd probably be Dr. House. Thanks for all the videos.
I recently learned that on some scooters the belt cover gasket is required. I've never had a problem leaving the gasket off on any of my scooters, but there are some where doing that will pinch your starter bendix. If you're missing the gasket, getting a new gasket could solve your problem. If you can't find one, you can always make it out of thin cardboard.
You had the right idea by spacing it out with washers, but I think a gasket will be easier to deal with. You don't need to go crazy tight on those bolts, but don't leave them loose either. You can add some blue loctite too.
Thanks for watching!
You might still want to do some fine tuning? You can mix the weights, you started with 6.5g times 6 and it gives you 39g total. If you take half of them out you will have 19.5 and that's probably litle to light and the engine probably would rev over the power band.
You got the best results with 5g weights, that might be just a little to much or a little to little. Maybe you might try with 3x5 and 3x5.5 giving you total off 31.5g off weight, the 0-30 time gets better you closer to the power band, if it's worse, you might want to try with 4.5g weights
The cvt is built so that you get the balance with 3 weights so be shore you have every other weight tge same.
All the best and keep up the good work
He's too lazy to fine tune it. He couldn't even be bothered to assemble it properly before riding it.
Top speed could be in kph 😮
Great video! Do you know if any of those rollers would work for my 2018 SYM Fiddle 3 200i?
No. The 200cc engine will have larger rollers. Dr. Pulley makes some rollers that will fit your scooter.
You made it accelerate better, because lighter weights means the engine has to spin faster before the variator will change the drive ratio, so it takes longer to change the drive ratio, and the tranny stays longer in high Torque mode,
You did not increase top end street speed, you did not make it over all faster,
You saved my wallet dude. Thank you very much!!
Hello,I just by a SXR50 APRILLA in france because I didn't understand well I think, (just here to work for 2 years) I was so disappointed because the scooter only goes to 47km .this is normal .
It dipends on ur scooter eingen lighter is better for ur 50cc but i have 125cc scooter where 6grams rollers are betrer
Yes gearbox differs. Some have 13 to on on 10 inch. Some have 11 to 1. The 13 to 1 is a picee of shit and fucking slow. Never look for speed or power on a 4t 50cc. 4t engines start to behave normal. Like 50cc 2t.engines when they are 100cc. Some of them the gear on the camshatft is pressed on the wrong timing
Thanks, we'll done :)
I have the exact same bike but 2009 model
so not exact same then huh?
The name of the scooter ?
I had a gilera skp50, it would easily do 50 mph on level ground and redline at about 56bmph downhill, i dont see why yours is so slow, is the exhaust restricted?
humm, i have a quad with a piaggio 250cc engine and it has great accélération but tops out at 82kmh... but get up there real quick.. i cant change rear sprocket they dont have smaller then 32 teeth and front sprocket is a special one i cant find and is already 19 teeth. so yeah i was looking into do variator weight help with top speed... since it has great acceleration if i can get the same topspeed with a engine that screams less io be happy also
changing the weight of the variator rollers increases engine rpm. Ideally, you find the rpm at which the engine has the most torque.
@@LabCoatPaul okay, it has alot of punch when u full throttle, it spins the wheels on dirt but then it kinda falls on its face lets say, i would like to have less of the punch, but i dont know at how much rpms it runs at max speed never checked. cause it feels like they put it all on the torque (which seems logic since its a quad with a scooter engine)
I just bought a used SWAN scooter. I have problem with it because when I start the engine, after about 5 seconds, the engine start to running fast and faster without turtle. The speed of rpm is too much. Please, how do I fix it. It is making too much noise and consuming fuel.
Start by adjusting the idle on your carburetor. Check out this video: th-cam.com/video/iCGjVRyN6YU/w-d-xo.html
This guy is amazing.
Hi. I have a gy6 50cc. Stock. Would it hurt anything to run 3. 9 GM. Rollers instead of the 6. 5 GM. Rollers? Some say it would be unbalanced. And ruin the c.v.t. thank you.
I've put a big bore kit 47mm and i feel a lot more torque on low-mid rpm, but i have the same rpm as the 49cc piston, so same top speed, what weigh do i need for take advantage of that low end torque? Stock one are 5.2 gram
Its been a year but get yourself 7 or 7.5 grams and mix match them 3 7g and 3 5.2g
I went into a smoke shop as they are the only ones who sell those little scales i needed to weigh my rollers and while browsing through the very large range I wondered how many drug dealers had stood in the same spot before 🤔
What weights should i put on MALOSSI RED SPRING +40% ? between 4.0g and 5.5g?
Kick starter doesn’t need to come off when removing the cover huh......
So lower the number on the weights, the more torque it'll have??
Can´t you just remove half the rollers!?
It would be too light
That’s not ‘faster’. That’s a greater acceleration rate.
Hi what was your real tops speeds with the 5 gram rollers? What roller weight is a good compromise? Have you ever drilled out a roller. 6.5. To. 5 gram ? Thank you. Bill
The rollers don't really affect top speed. They basically set how soon the variator "shifts" gear ratios. My scooter tops out around 35mph if I wait long enough. Start by tuning your carburetor for the highest top speed, then maximize your acceleration with the rollers. I have a carb tuning video here: th-cam.com/video/iCGjVRyN6YU/w-d-xo.html
Is this method is used for e bikes also
Name of the app please!!!!!
You ended right when you start to see improvement, try some even lighter rollers and measure what changes.
:)
I will do a more in-depth transmission tuning video soon. What that scooter really needs is a new torque spring (contra spring). If you look closely at 0:27 in the video, the belt doesn't ride all the way up the rear pulley, so the scooter never goes into the lowest gear. I also happen to get the worst acceleration from 0 to 10mph.
So smaller rollers is better?
Thanks for the content
Really appreciate..
I just understand to quick start the bike we need to use less weight of rollers ...
Top speed will be slower though so if I was you I’d do a mix of both every other
I have lance racestar 50, using 5g weights with performance variator and performance clutch with hi flo carburetor and scooter goes 0 to 30 in 7.5 seconds with top speed around 39-40mph, I'm happy, it runs better and quicker than when new from factory!
What springs are in your clutch ?
@@donrodriguez8615 I know the big spring is red so I would think the three other springs would be the same, I bought the clutch assembly new but didn't pay any attention to smaller springs, is the big spring called contra spring?? I forget,
@@wackingjack yes , the smaller springs are the clutch shoe springs
@@donrodriguez8615 correct! I'm laughing to myself because I brain dead for a second, them immediately remembered as soon as I hit send button! 😀
Wow, it really took over 30 seconds just to get to 30mph? That's mad slow! Maybe it was just the area you were testing in? I'm over 200 lbs and my 49cc scooter (before I installed a big bore kit in it) was able to go 0-30 in less than 10 seconds! It only takes me half that now!
SegaDisneyUniverse is yours a two stroke?
@@robertausdemore7855 No, it's a 4 stroke GY6. Mines a Chinese scooter as well.
@Felix Nilsson Mine was Chinese as well and go faster than that, even without a big bore modification I can go 0-30 in less than 10 seconds on the scooter I have now. I just bought a new scooter for $1,100, 49cc with a 125cc body.
@Felix Nilsson Well again I own a 49cc Chinese scooter, they're not made to go super fast without illegal modifications. I'm getting around just fine with a slightly slower vehicle, thank you, lol.
@Felix Nilsson If only the law allowed people to operate a scooter over 100cc without needing a motorcycle license, depending on your state/region. It can be unsafe being the slowest on the road, especially with a lot of impatient motorists around.
Thanx doc
