Gy6 scooter transmssion upgrade

[@megadawg342]

Well done. Yes, I too use the Yellow 1500RPM Torque Spring with the Blue 1000RPM Clutch Springs for a less abrupt smoother take-off. and engagement. Plus it stays engaged longer downhill off the gas before it freewheels.

[@thedownhillerboy]

Yeah it looks sweet for sure, I got me a just as sweet if not more CVT set-up on my Yamaha BWS/Booster/Zuma too... I also use to have the spring housing upgrade with the bearings there,it improved both take-off and accelerations but I ended up removing it because a more experienced friend warned me that this part is preventing the speed drive's pulley from opening completely as the bearings housing is creating a kind of a step to the torque spring which's taking some travel away from the pulley which in time isn't allowing the belt to reach the center area of the speed drive's shaft. Ultimately this translates into loss of top speed as you're not seizing your speed drive's full capabilities. Malossi's yellow torque spring guide for the opposite end of the spring also creates the same problem as this part's also a bit too thick 🤷🏻‍♂️...

[@f1guremeout]

Hell yeah, I'm planning to buy this exact setup for my GY6 150cc. I'm excited!

[@JorgeLopez-sv2tv]

You are amazing brother I really like your work my dream is to have my 150cc scooter like this😊😊

[@sycodad4483]

I have a Naraku super trans. I think it had 6 gram weights with the kit. I used the stock torque spring I believe is 1000rpm. After riding it 30 miles I pulled the trans cover off to check everything. The belt does not climb all the way up the drive (rear) pully to get lowest ratio. Tried a 1500rpm torque spring but that gave me high rpm's and no speed. The belt still didn't climb to the top of the drive pully

[@justinbowles4671]

Will the clutch cause my buggy to slip ! Like very badly!! Lol Every time I go to take off it slips and jerks and won’t stop

[@samuelmf]

My friend thanks for your video, i have 2 questions: 1.- I have a 150cc scooter, what spring color you recommend me to use? 2.- For what reason, when I start accelerating the motorcycle, if I accelerate it quickly it starts to make small jumps, but if i accelerate slowly it does not give those little jumps a little bit. I need to purchase a new clutch?

[@billtevepaugh]

Sounds like your rollers have flat spots.

[@MikeHayes-v7v]

What happens if kick start only spins don't engage gears or the electric start don't kick it over And variator just spins clockwise and counter clock wise don't engage gears what do I do

[@sonny1980]

Will the performance clutch pully from NCY work on any clutch?? Thanks in advance. I’m thinking of replacing my stock.

[@holohulolo]

Whats the benefit of changing the rollers into those sliders. Also I have a clutch housing that seems to have worn out a little evident from the marks where the clutch makes contact that it's thinner on that area.

[@Roland-Henry]

Hi, I purchased this exact transmission kit and have a question. There’s a sheath that came off the top of the stock contra spring, does that need to go on top of the NCY yellow contra spring when putting everything back together? Thanks 🙏

[@megadawg342]

yes

[@neonfluxthunderform2790]

what kinda flyball are you using sir?

[@ajc5601]

Hi can i ask? All this upgrades on variator, will it affect the engine? Like will it cause more wear and tear or stress on the engine?..

[@zdenocharakter9616]

too low rpm (heavy rollers) can make more engine wear.

[@danielmoore394]

Hey man! I just got a tomos velo 150cc... 2009... would all these parts and things you talk about in most of your videos fit on this scooter? Do you you know?

[@lester6340]

Have 139qmb can run 1500 compression spring and 1000 cluch sping

[@anthonymacaluso1488]

Hey buddy is there a way to get a in between contra spring ? Seems like the yellow 1500 shifts too fast and the red 2000 wont shift till way late. Should i go yellow with lighter variator weights or keep the heavy red amd add more weight to variator weights

[@PeterPiccolo]

is there a prebuilt clutch upgrade option so i can just slap her on? i have a 2020 wolf rugby 2 49cc scooter, i just changed the oil and she is actually faster but i would love an option like this, anything to help it go a bit faster... is there a prebuilt option for the clutch system on my scoot? thanks soo much for this video such a great help!! -p3t3r

[@masoodn8]

Hi I want aprilia sr 125 all clutch sets witch I can buy tell pls

[@cemtkeenan2750]

As for clutch springs, can we mix and match weights? For instance 1500rpm yellow on clutch pads and use 2000pm red Torque spring? Asking because thats what extra springs I have and Im afraid to experiment .

[@dkewlguy]

First of all. Why is that clutch nut gigantic?!?! And you said you glued the seals on that secondary pulley? What does that mean?

[@tackfarinaszeus57]

I think he meant "apply grease" lubricate .. not glue

[@dkewlguy]

@@tackfarinaszeus57 ah that makes more sense. Thank you

[@joebug5599]

why did you choose the sheave slot with the curve and not the straight slot? what is the difference between them?

[@robertpaschal7645]

I have a 250 Y G6 looking for some carb upgrades and what would be a good clutch performance that I could put on it or would this one work get again mines are 250 automatic GY6

They should had emadethe bearing for the tork spring with rollers instead of bearing balls.It would have made it way thinner.Same prinsip is used on top of car spring damper strutof MC Pesron suspention

What is the best setup for standard gy6 50cc 4t springs???

[@travispage3020]

Btw love all your vids and how do you like the plug and play efi?

[@MRSPACEHAMPSTER]

Hey rolling wrench, what kind of grease are you using? any substitutes?

[@justahungrygamer8303]

Hey thanks for sharing all this info your videos have been a great help, I need to replace the stock belt on my chinese scooter because it shredded. I'm almost sure it was a 669x18x30 jonway belt, if I cannot find a Gates kevlar belt will a different brand kevlar belt be worth it? or should I just get the gates rubber belt?

[@christopherwebb7940]

The upgrade on this clutch was it done for a Moped or a go-kart?

[@juliodiaz4493]

The lighter the rollers the better right

[@juliodiaz4493]

One question if I put a performance carburetor that I bought I have to change the spark plug

[@Chizbizzy]

Do you use grease when you pack the bearings into the sleeve? Assembling now and it wasn't clear in the video if you used grease in the ball bearing sleeve

[@dylanjosselin]

I have the NCY seat on the secondary, and the bearings are packed with high temp moly

[@travispage3020]

So I bought a ncy complete cvt performance kit and put 12g sliders in and came with 1500 "yellow" contra and three 2000 "red" clutch springs.. The motor is pushing right at 180cc and when I give gas it takes forever to actually move... I. E. High rpm What am I doing wrong?

[@martinfrankiewicz7820]

No one tells you thats what the ncy supplied component set up does. It did the same shit to me and i hated it. Yeah its great if you love screaming down your driveway and going no where. I had to rev up to about 4800 rpm to get any engagement and was pissed. My engine ran at 8200 rpm and actually lost top speed. Complete opposite of what is advertised out of the box. Now i have two sets of tuning weights and an engine thats been into more than i can count.

[@marco21falcon]

I am just over the mountains from you. About 5k ft above sea level. My buggy has a gy6 150. Three gear ratio changes way too early. So my climbing just bites. Got any suggestions for clutching? I don't want it to slam into gear.

[@Lukas-nq2ic]

I have 80cc, perf air filter and i only get 75km/h on flat what roller weights i should use?

[@monty81567]

Hello.Where did you get the sleeve bearing at,a local parts store? Where does one get the upgrade ncy slider at? Went to your website & didn't see them on the list.I know this vid was in 2016 and now it's 2020.Are you out of those's parts?

sir i would like to ask , i have yerf dog spiderbox with a gy6 engine in it i would like to know or if you can give a combination not only in cluth and variator but in carb , camshaft and weight reduction too i would like it to perform faster without loosing to much torque thanks in advance , great video

[@predator_boiz336]

How much is this clutch set up? any links?

[@danielmoore394]

Like are all the splines the same pitch and tooth count?

[@MotoVice]

sir can i ask? does the performance clutch lining and lightened bell have anything to do with the speed and acceleration of your motorcycle? and what is the difference with the stock? thnx a lot sir.

[@RollingWrench]

Yes, a lighter variator will supply a faster throttle response due to its ligther rotating mass. the lining (teflon coating) is there to supply reliability. belt dust wont build up as much on a teflon coated variator.

[@derekmaxwell8164]

@@RollingWrench is this kit good for an offroad gokart? Im looking for one that will do good on extreme hills i need lowend power more than anything dont care about top speed.

[@Edramirez432]

Just curious would the bearing part work with stock setup or has to have ncy setup for everything?

[@julianarodriguez3635]

Can I see the tool to install the spring

[@badmonkey2222]

What clutch and varriator and what weight sliders would you recommend for a 50cc bored to 80cc scooter? I get about 48mph now on flat straight and 56 downhill but my prob is it bogs down bad going uphill only about 35mph, I'm looking for more tourqe more top end where I'm not winding it out so much and more uniform speed and power uphill, I've tuned the motor about as much as possible, racing CDI, racing coil and performance plug performance exhaust with minimal baffle and super flow carb, I've just not messed with the transmission yet and I know that's where my prob is . Please help.

[@GarethKing1]

I would recommend a larger engine, 50cc bored to 80cc is very agressive so you shouldn't push it to the limit, it won't last very long (unless the OEM 50cc was incredibly overbuilt, which would make it exceedingly heavy on a low-power machine). 125cc are cheap.

[@Kuyzz_Dunkin_Vlog_Official]

wow that is great.. Can you help us also to upgrade mio sporty.? I can't find anything on how to upgrade it.

[@androidken]

How the hell do you get the belt back on when using a contra spring that's 1500+? I can squeeze the pulley at 1000 to slip the belt on the clutch but using the yellow or red....there's no freaking way. How do you do it? I can't seem to find anyone actually showing how they do it.

[@dkewlguy]

You can do it with your hands but you really have to spin it and not push. I put the belt on my hands with the clutch in my hands as well. So when I get it pushed in a just slip the belt in

[@repnatl]

I'm using the 2k contra spring and have no issue putting the belt back on. I slowly rotate the belt around the front pully, and it slides on even brand new. Never had an issue.

[@zenargaming1257]

is the thing with bearing durable? how long It'll last?

[@RollingWrench]

Yes, very durable. I have had one on my 232 scooter for 3 years now

[@zenargaming1257]

@@RollingWrench i hope I'll find one fitting my nmax. any changes with the performance too?

[@marco21falcon]

I put a yellow 1500 rpm torque spring in. Should I try that then see if I want different weights?

[@ace5gen233]

marco21falcon Did it make a difference

[@marco21falcon]

luis rodriguez yes....it made a big difference. It did not affect my top speed. But it made it remain at a lower gear longer so that I could use what little power there is. I have a 4person gokart 150cc gy6. I also went from 14g weights to 10g weights. Even better!
