How to get more TORQUE out of GY6 150cc SCOOTER 

Ahh man i looked forward towards installing that cdi too. Thanks for the shout-out, I'll dm you guys.

In case you guys weren’t aware, some gy6 (really any cdi equipped engine) are setup to use an ac cdi and some use dc cdi. The difference being obvious, the ac is for alternating current and the dc for direct current. What does that mean though, simply, the ac models generate their own electricity (ac voltage) to power the cdi whereas the dc requires 12 bolts dc power from the battery for the cdi. The ac equipped bikes will run even with a dead battery. How to tell the difference easily? If you turn the key on with the engine off, if the headlight comes on then you’ve got a dc cdi typically. This of course assumes the battery is charged so in cases of a dead battery then hook up jumper cables to a car first before the key on light test. Also a dc cdi is typically about 1.5 physically larger than an ac cdi because it has more circuits inside for the dc portion. Most 50cc are ac cdi. It’s a toss up on 150 gy6. Most kymco are dc except for the two stroke kymcos are ac. Most all two strokes are ac for that matter. Some rules of thumb regarding clutch and cvt. Roller weight controls when the variator (front pulley what you guys called clutch) “shifts” from low “gear” to high. Lighter rollers aren’t thrown out by centrifugal force as easily so the variator won’t shift as soon/in other words the engine will rev higher before it shifts. The opposite for heavier weight rollers. Top speed is a function of horsepower and final drive gearing (there’s a small gear set behind the rear pulley/centrifugal clutch ) unless you’ve got the cvt all out of wack/engine running poorly/extremely low on power. For optimum performance you will need to tune the roller weights and the clutch springs that hold the clutch shoes from engageing the bell. There’s also a “conta” torque spring under the clutch in between it and the rear pulley sheaves. A slightly stiffer contra spring usually helps it stay in low gear longer and keeps the belt from slipping too. The ideal setup (once all tuned right with rollers and those springs) would be clutch springs that let the engine rev up to peak torque (think stall converter in an automatic trans race car) before they engage the clutch, and light enough rollers in the variator to let it wind out (use all of it low gear) then shift into high and let it rev till top speed (gear ratio determined/rev limiter determined)! As far as Amazon stuff goes, the yellow contra and clutch springs are usually a step stiffer and quite noticeable improvement for $10-20. If you go brand name like Malossi or Polini then the colors may or may not be the same. There’s clutch springs available that will stall anywhere from 1500 for those yellows up to some full race 8000rpm springs. Cvt tuning is the first place you want to get right! Night and day difference. Those Tao Tao 50s in your other video will go 40 mph with yellow contra and clutch springs so long as the engine is running right which 90% of the time is just making sure the pilot jet is clear (there’s a tiny hole thru the center not just the four holes going sideways ) and the rest of the carb is spotless. Those engines are simple. Those racing cdi don’t truly do anything except they run full advance at all times (in other words they don’t have less timing advance at low rpm to make the engine easier to start like the stock ones have). That’s why it felt snappier off the line but once revving the are identical after the timing curve kicks to full advance. It’s been proven on the dyno and with timing light and ossilliscope. Actually with a big bore kit with high compression the stock starter won’t be able to start it cause it’ll have to much advance at idle/start rpm. Welcome to the addicting world cheap scooter mods! It fun asf isn’t it😂

I'm just messing with you guys but I'm doing so much work on my own to make it go faster watching rolling wrench getting good ideas you guys are doing the same thing but I don't know what state you guys are in let's rendezvous this summer and I'm going to show you how fast my GY6 scooter is

Cool will it work on a 50cc with the big bore with full mods as about do one what do for think good fun. Jeff in UK

I've been messing around with mopeds for over ten years now and it's a blast watching you do stuff that I did way back when (and remember why....?). Keep up the great work!!!!

People hate on Chinese scooters, but I've owned a dozen bikes, and nothing has been more fun than working on, tuning, learning from my cheap piece of junk(when I got it) "Chooter". They're tons of fun, and if you drop it, slide it, wreck it, whatever, everything's cheap af, and easy to fix with basic tools. people that, are just late to the party imo :)

HEY I JUS GOT A 2022 50CC GY6 CHINNESSE SCOOTER N IM LOVING IT!! IM DOING MY OWN WORK ON IT CUZ OF U GUYS!!!! RIDE SAFE AND BLESS U ALL!!! MOPAD LIFE

Good wheelinging I have a 150...cam ..slide carb pipe gearing. Big bore kit...cdi....62 mph flat ground.... Willets 😮 California....71 year old Yahoo

This is my first of your videos and I subbed so fast! I was a scooter mechanic for 2.5 years and after a few years of driving cars I'm ready for like my 10th scooter. Gonna get a 2021 Peace Sports 808-7G from the dealer I worked for. First upgrades: Serviceable carb with a 114 main jet. Performance clutch, cdi, air filter and exhaust. Ankle bitter. Under glow.

Just installed a 47mm 80cc BBK on my Tao Tao, things got well over 10k miles on it but runs like a champ. went from 30 MPH when i first got it to 40 after some basic derestriction and tuning, to 50 MPH after the BBK. Still got some fine tuning to do on the carb and CVT upgrades on the way.

Friends, Haha 16:47 My wife saw this and said, “Is he disabled?” Next question, “That is how he cleans his shop, with his pants?” Hahacha great video. I would like to see top speed comparison of the different weights. Thank you, Kenny

I have 200cc tyien chonese beast.. did carb and exhaust what variator/belt/weights to get over 70 hits 69 and moves

Y'all the reason I want to get that orange muffler for my Tao Tao 50cc scooter. I want to talk to y'all bout my scooter.

i honestly don’t get why you don’t have more subs

what is the rpm of your clutch spring and torque/center spring?

I bought a clapped moped for 75 bucks, blew up the top end didn't get all the metal out and blew the bottom end, just replaced the moped and still don't even have 300 in to it lol things are great to beat on

I just got an ‘87 Honda Elite 150 I stripped down to the frame, opened the air box up a little and chopped the giant OEM muffler off and rewelded the actual pipe, to save on buying a muffler lol. Rolling wrench has some good products for sale to help dial in the carbs after mods, so you don’t have to buy a whole bunch of jets you’ll never use. I’m gonna add a tube across the front forks to tie them together and weld two pipes from steering neck back to passenger peg frame to add stiffness and better corner handling. As these scooters around corners feels like a water weenie trying to hold a straight line/curve

Just rebuilt a tgb r50x not one of the best bike but just starting small , watching you guys on getting bike to go faster I put a sports cdi on it going to try 6 gram weights see how that goes , great show guys

I have a purple 08 Roketta with the same body plastics. 50cc with a BBK, CDI, 20mm carb, open exhaust, and 6.5 gram weights. I get 47 MPH all day. I'm building a new bike out if a free junker. 50cc with a BBK, CDI, A9 cam, 18mm carb, open exhaust, 8gram weights. Also 47 MPH, but quicker.

I have a 50cc TaoTao it wants to bog down at top speed. Put new carburetor on and removed pet cock put on shut off valve directly from tank to carb. Also removed air box put on the air pod that came with carburetor. Any suggestions? Could it be something in my tank restricting gas flow.

Just bought a cheap 150cc scooter. $200 and it’s a 2020 with 1.7k miles. No spark but everything else looks good. Cleaned up the pickup and waiting on a new CDI box and plug wire, very excited to get this thing back on the road

I just bought a 2001 Honda reflex 250 which we call a Honda Forza here in Australia. I just bought an aftermarket performance exhaust that I had to order from japan and can't wait to do it up.

Do you know if the cdi box you used had the male or female hookups? Does it matter? I’m new to this but I order one already that wouldn’t hook up to my scooter

I'm trying to put a 250cc motor on a 150cc how do I go about that

Clutch weights?😂😂 It’s the variator weights, the one you took apart is the variator, the clutch is the other one that you didn’t touch 🤦🏼‍♂️

Just got a moped and I'm trying to make it faster

Any recommendations for a Vitacci Clash 200 EFI? Hoping for the best, have heard some recommended modifications and found one in decent condition. Thank you guys for the vids!

I am in Michigan. I've been following these videos as I work on De-restricting my Wolf RX50. I have not found any genuinely low restriction muffler and headpipes. I ended up fabricating both an intake and a muffler system. I didn't see any point to upsizing and rejetting a larger carb until the restrictions were removed. I don't want a 55mph scooter. But one that is better off the line and has a bit more mid range torque. I'm trying to avoid doing a "big bore" kit and a cam. But, it's within my capabilities. But this scooter doesn't have a good suspension for 50mph and Michigan's shitty roads.

Bros, y'all are hilarious, I have a 150cc gy6 and I have the performance rollers and I get the same type of response off the line. But I'm going to have to get that CDI box you guys I got so I can dial it up. Thanks!!!

Hey man been watching throttle therapy. And decided “well hell” now I bought a dongfang super 200

When you are putting the cover back on, put the kick start on and push it down a little so the spring comes out . Bosh

Happy to see a channel doing scooter stuff in 2021. 139qmb and 157qmj owner, these little motors are awesome.

How to get to top speed faster on a moped

I seen a kid battery powered dirt bike somebody was throwing away of course the battery is bad and it was one of the better dirt bikes have front and back shocks and brakes took the batteries out of it put four 20-volt drill batteries in it note the little box for the throttle is only rated for 36 volts but it would peel tires with me on it I'm 186 lb

U should've put dr.pullys roller weights on. Way better. All rounds one are trash.

I'm curious. For some reason I can't fathom you guys call scooters 'mopeds' a name that has been used for years in Europe to describe (usually) 49cc bikes that have both a MOtor and PEDals either of which can propel the vehicle. Think about the millions of Mobylettes, Puchs, Velosolex, Peugeots, Zundapps, NSUs that are around (and to a lesser extent Hondas, Yamahas and Suzukis). So what do you call actual, well, mopeds?

I'm looking for the links to the CDI box and the bearings!! I need those ASAP!!

I have a Rockford Tora with no engine and have a lead on a Taotao 150cc GY6. Could I put a 420 sprocket on the output shaft, mount the engine forward and put a chain from the output shaft to the rear sprocket?$30 for the engine but I don't want to waste the time on a non productive project.

The only torque increase Is gonna come from a bore kit. Everything else is just making it respond faster. A cdi is not gonna increase spark... only allow a better spark. Weights will make ur rpm change. Not add low end.

i got scooter look like ur 150cc red and black on a basic black one i can hit speeds of 50 it putter for first few sec befor start moving up to 50 and i belive almost 60 with basic black one mine only have a maby 1000 miles on it or still in the 900 just seem to have proplems with hair coming out the oil yes i said hair coming out the oil rubbery black stuff from spark plug and dead battery good thing only cost 140$ and little tlc and running great

I put a cdi on my new chinese gy6 from amazon and the exhaust manifold gasket blew out lol.

I will be over to give you guys a wheelie lesson soon.

I own a 2013 Kymco Super 8 150. How do I start making it faster? What mods?

I've got Tao Tao with 80cc 47mm stock everything else goes 56mph

My dad has a lance pch50 that I started tearing into sat for 2 years was filled w. Water

Definitely a little late seeing this video but I've got 3 mopeds 2 are 2 wheelers and 1 is a trike. I'm getting a high performance clutch for the trike so I'll have to see how that goes but Definitely nice seeing scooter content.

Hi my big Boy rivival scooter takes 10 seconds to pick up speed

Hell yeah! Im for sure going to stick some fresh weights on my GY6, your bike looks hella fun now!

F lmao you guys having a blast buying me one today lolol🤣

I got that same cdi I guess it works good couldnt tell the difference with just that but when I fully built or put on all the bolt ones I notice a bigger difference now I just put a bbk and new gears so I wanna see what's the difference

Did yall ever do a clean air mod on this one? I finally started ripping proper wheelies and every time I do, theres oil Everywhere.

Efi for about three hundred and probld cylinder piston cam kit.

So I just cleaned my jets out but now it stutters to get up to 30mph its a 50cc gy6 thanks in advance

I don't like how they're abusing that moped & laughing like its a joke, I bet if it was a ninja kawasaki it won't be funny!

Your never ever going to work on my scooter…..LMFAO.

I'm looking at different scooters and I learned what got to be done to Chinese scooters and watching your channel helped me but now I have to what type thank you for the video

My scooter whont start bit I'd sounded like it was the starter but I switched it and was not the problem

Do you add heavier weights or lighter weights to get better torque out of the scooter?

I have a scooter 50cc but I have a 100cc big boy kit but it's still a 50cc I do have the kit on

It matters which way the rollers go in too don't forget to mention that in your next video

I go to the cdi box link and it says page not found … is it still available???

Im buying a 125 to swap my Golfcart 😅🤣

Gave you a like just for the hoverboard nonsense 😂

That's not clutch weights that's variator weights or sliders.

my neighbor moved out and gifted me a free 2005 schwinn moped with 49 original miles. ill be buying a new carb and posting off road videos on it

More torque means higher temps, just sayin.

ac and dc matters .......you can cause damage with the wrong cdi

I love your videos. I have. 2017bTao Tao. I installed an 80cc big bore kit... Cylinder and piston with gaskets only. Unused my existing head,valves, and valve cover. I had 10g and 14g weights (alternated in varistor) my bike was slower on take off but my top speed was 56mph. I couldnt believe it. The kit cost me 26$ with shipping. But 2ith the bike riding faster I began to experience a wobble in the handle bars and the vibration of the 80cc was making bolts and nut loosen. Was weird but kept eye on them. My 200$ ride could go 50-55mph easy as hell for under 30$

Can you use this on any mopad or dose it have to be a certain type?

really good content

My carb needle broke at the skinny part will the bike b ok to ride

I have a custom made 150cc moped great bike but I want to go way faster I want to be able to hit 75 on it so that I can go on the highway to get to places Icant get to without a car any ideas on what I could do I already spent 2k on the bike any ideas

bigger hammer

I just put my transmission together on my 50cc summer and I've got six and a half gram rollers mixed with eight and a half gram rollers and it's maxing out at about 45 on it straight away I want more torque what kind of spring should I put in the clutch I want the needle to bury 50 mph it's going about 40 42 mph I'm not going to say 45 because I let off the throttle when it was about 42

I want to buy a V150Ss it has the GY6 engine but they are very not reliable and getting is used one is garenteed to brake down

Does that part work for tao Tao 150

bought what i thought was a 50cc and it turned out to be a 125cc!! it has been totally overhauled inside and out and i would love to share what you guys inspired me to do and it to become ;)

I bought a Big bore kit but I haven't put it on because I don't feel like I need to do that it's running damn near more than perfect actually it is because the book only calls for 25 miles an hour top speed brand new I've got it going 42 miles an hour and that's the bottom number that's not the top number it's f****** nice

What if you just take out and lave out the weights!?

i have a 150cc gy6 yamaha scooter , im thinking of slapping a fat carb on it and a nice exhaust with maybe a cdi?

Not sure how to DM but came across your channel researching. I am thinking of flipping mopeds any advice for starting out

I got a 150 cc VIP bc of yall

you guys are awesome ....i want some stickers

Bro thank you so much, my 50 has been stuck at 28mph for ages and now I’ve just orders a cdi,exhaust and carb

I have a dongfang DF50SXR with a 50cc gy6 and yall have helped so much with my fine tuning and everything I plan on watching more of yalls videos I just need to buy rollers and a ac cdi box to get it up to 60mph oh and by the way I'm Charles this is my mother's account since I broke my phone working on a vehicle story of my life and may God continue blessing you all my brothers

😂 good laugh 😃 🎉 keep your cool 😎 great 👍

If you want speed to add a Gearup Gearto it.

Following for more. Just bought my first 1p57gmj powered ruckus knockoff and am in love with scooter life.

about to buy a 150 peace scooter gotta get a cdi

Hey guys plastic, I need some help. I have a 2012 Daytona Propel , I have upgraded any parts But I am struggling to keep a bolt in the exhaust pipe. All the parts I’m loved are brand new. Any advise?

Well let me start you try and show me what to buy you take the box you waved it around the camera couldn't keep up and focus so I never could tell what the hell you did thanks

I watched this vid like 3 times. You guys are mad funny!!

cut the pink wire on the cdi unit

Too bad. No hospital visit yet !

these gy6 covers with kickstarters are a pain in the ass, i spent about 40 minutes just to put the cover on

and the rear brakes is weak

You guys should try to get anything with a gy6 to do 100mph!

Keep the vids coming

Zummer not summer sorry typo
