@@WaldensWorld thanks but here in NZ it takes a month for it to arrive so I pressed out the center steel rings and drilled them out than pressed the plastic sleeve back on, now they are 4g and it's a good top speed and it climbs hills very fast.. I appreciate your advice ✌️
i heard belt slip witch is common problem on many gy6 do to small diameter variator and clutch assembly.Stiffer tork spring in clutch assembly and balance that out with heavyer roller to create more pressure on the belt sides for better grip.Also go up from 18mm wide belt to 18.1mm same legnth and angle on sides, give a longer life before it slips again with stock weak tork spring
Did this on my gy6 buggy it help out a lot I had 13g rollers it was bogging up hills I put 3 6g rollers in it did better thank you going down hill with all the 13 g rollers in I hit 34mph now with just 3 6g rollers I hit 46mph down hill
Love to hear it . Now you got springs in the rear clutch the stiffer the more rpm it takes to engage want to pull wheelie ? All kinds of mods ! Be safe n have fun !
very impressive it does not vibrate at all. I have 2 different scooter (SYM & Yamaha). It will vibrate the scooter (move backward) when I give it a gas.
@@WaldensWorld I curious. I have watched some of the videos regarding CVT modification but none of them mentioned about grinding some bits of variator itself. Over here, those modifications are the simplest way to get a higher top speed.
Yes the pin can be shaved causing the face to compact more . I've played with longer wider belts too ! Nice to see you doing other things ! I like them fast n ugly !
In gearless scooters, should we apply little bit of grease on round shaped 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, sides of rollers get flat faster, vibrations will increase etc ? Please tell what should we do with proper reason.
@@WaldensWorld 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?
Depends, most suzuki cvt variators are grease type, meaning they have a small metal piece at the engine side of the variator held in with 3 screws... Those variators NEED a littlebit of grease (i use machinery grease).
Dr products are good ! But I’m not sure what your oem variatior came with some sell kits with few options I’d either weigh yours first or buy a kit with like 5 different weights ! The heavier you go less torque n more topend ! N you can do springs in the clutch itself !
@@WaldensWorld l don't know how l should find out the rollers weight in my scooter, so if you could possibly find out and suggest me what or which type of rollers l should use will really be so helpful, txs
what would happen if i removed all the weights? Then it would be super light but the variator case is heavy. Do you think that the variator case is heavy enough to change the gears?
I'm not super informed and experienced in this subject, but from what I've read and seen, you'll just stay in the lowest gear all the time. At higher RPMs these rollers start to go further from the center and because roller casings are angled, it makes variator sheaves (plates) move to each other, further and further away from the starting point. If you take out rollers, there won't be anything to force sheaves to move inward, because variator sheaves seat rectangularly to the main shaft (I guess it's called boss, idk) and centrifugal forces won't cause them to move parallelly to the shaft. Good luck :)
Sandro Chomaxidze u sound legit lol, what do you think about the steep driveface i have on my 50cc. I think its dr pulley. I dont think my red 2k clutch likes it. Scooter Shudders or studders when im at 40 and wont let me get my last 6 or 7 usual mph on the top end?
Okay so I tried to put in new roller weights when I put everything back together it’s made a clicking noise as I gave it gas in went away, then I put everything back together again after trying to find the sound/source and my variatior exploded on me and my tire was moving backwards would u happen to know why? Thank you
hi please can yo keep things simple for me , i have a small quad bike 100cc ...cvt drive ...i have no interest in speed but want to tow a small garden trailer , what can i do to make the engine not work to hard and keep the torque up
Do you have a chain n gear system at rear ! Smaller front sprocket bigger back ! If it's belt drive a smaller rear tire would give more torque ! You the belt drive can be modified but without . Actually gearing it down that will only help a little ! Lighter variator wights will keep belt in lower gear ! Thicker rear clutch springs make it ingage at higher rpm 2000# 1500# ect giving more power take off !; Hope this helps !!
I’ve got a 2021 znen 50cc jog. I could be running flat at 35-40mph and hit a hill and drop instantly to 10mph. I weigh under 200lbs. What would be the best set up for this qmb139 engine?? Any suggestions would be appreciated. Thanks guys.
I’d look into a big bore kit mallosi makes a nice 70 kit n two strokes are not to difficult to do ! Pipe n jets ! The jog don’t have a huge amount of aftermarket stuff unfortunately! But I know Mallossi makes stuff for them n kits are excellent
If your running a cvt belt drive your rear clutch has springs that expand at different times find different springs That are thicker aka come on later ! This will allow motor to stay at higher Rome before engaging! This will keep torque n power high !!
Cutting the weight by HALF is never going to be the right answer. You need to FINE TUNE by trying weights just a little bit lighter. Small adjustments are the key. Often need to mix 2 different weight rollers in alternating pattern to keep rpm in power band the longest without compromising top speed too much. Baby steps
In the video I definitely said lighter weights would be first and this was an experiment it cost nothing to do it , it definitely worked and as far as three support aka rollers my Polaris 500cc quad also only uses 3 pushers in the variatior! Weights come in a lot of different sizes ! What’s half were they stock rollers , if you have time n money yes fine tuning is key , this particular video is for those people on a budget !
Thanks. I’m rebuilding my first scooter right now so learning every day. First ride today and not impressed with initial acceleration or top speed. I’ll keep trying but ten year old scooter and only 50cc so could be hopeless. If there’s not enough compression or horsepower at the driveshaft the transmission can’t compensate for that
The clutch spring can get stuck also the variatior runs on a pin deal if it’s wore on shaft it causes a little wobble n loss of acceleration can occur! I’m in the process of making a every thing that can go wrong with your scooter video it may have to be a series lol top 5. 10.15.25.30.35.40 ect thing that cause your scooter not to run ! Muddobber nest in exhaust or vent lines too if it’s been setting lol
Bro, can you suggest me something, i was having issues climbing uphill with my aprilia storm 125, but after i used a stiffer spring with 3*20 gms rolls setup, i can see a considerable difference but will it decrese my mileage? Or breakdown somewhere in the middle of the road
I wouldn’t think so with a 125 but I’m not sure if original set up ! If you lose anything it would be minor ! I think you have enough hp to get up to top speed !
Nice ! That has to be fun ! There is a app on phone that I can use it will tell you data on launch speed distance ect ! I plan on using it to see results before n after I build a stroker scooter
Yes it will take off quicker but you will lose top speed without enough weight to push the variatior all the way out ! You can buy lighter weights n play around and have all six if you can afford to do that ! The rear clutch tighter spring will engage at higher rpm for better launch
I have moterstar easyride 150. I change lining, spring of 1000 and 1200 central spring, and 12g balls. But still it does not claiming even simple hill. Can i know whats the problem with this and how can it repaired?
Does your carb have black plastic top ? If it does pull it apart n get the needle out n move it up one notch nice c clip down one notch try that for power let me know !
They would help keep it in lower gear . You can also put a tighter spring in the clutch do instead of engagement at say 1200 rpm you can get one for 1500 or 2000 . Then when clutch hits it hits alot harder !
@@WaldensWorld I was told that the lighter the rollers. The better. I just put in a big bore kit. And was going to put in really light rollers. 4g. So if I did the 4g and a tighter clutch spring. Would that make it have better torque???? To do a wheelie?? Or just jump off the line?? Just with 5he bore kit I get 35 mph now. Up hills instead of 15-25. Depending on. From a dead stop before the hill. Or if I'm turning into the hill. Etc. But please let me know the best way I can get the most torque out of my scooter please🙏🙏🙏. Cause I keep hearing different things about the heavy vs light rollers. Thank you
Interesting but I’d think because it has rails to help guid it with just a ball bearing it may bind ! Also if you got a steel bearing that thick I think it would weigh more than the rollers ! But I bet if it did work it would hit hard be fun to try !
You can open carb pull diaphragm out raise needle one notch . Try that out !! If you have needle with no adjustment get small washer like finger nail thick n use to raise needle ! Try that out !!
@@robguy49513 years late but thought I'd mention the obvious, raising the needle one notch allows more fuel in, as in, move the washer down one notch. Can't get leaner than before unless laws of physics get rewritten in the meantime.
Hey , i changed MALOSSI Torsion spring red... and malossi red springs 2.0mm on my yamaha aerox. And the take off is very bad... what should i do? Install the 17,5mm carb?
Only change one mod at a time . What weight rollers were you using? N springs are just tension u want same length but some will be thicker or thinner causing resistance
I have znen r8 2018 50cc its not good but do u know what i cant do to make it better its slow at acceleeating but i can go 85kmh up hills very slow and i think its slow cause of the oil that i need to change i have no idea
Look into a 100cc big bore kit few hundred dollars but will make a huge difference ! If you needle in carb is adjustable try moving the clip down one notch take the screws off top of carb remover rubber boot n get needle out some are adjustable some are not ! Ps don’t lose clip do it in area free of junk invade you drop anything! Let me know how it goes
I have a JAGUAR-200 (169cc) DELUXE Go Kart, Single-Cylinder, 4-Stroke, Horizontal Type, Air-Cooled. I noticed it no longer goes into higher RPM. I dont know much about these engines. What i did notice when i first bought it was it had 3 levels of RPM- power(according to how loud it got when driving it. It no longer goes into "lvl 3" aka the louder more power RPM. It only has 37miles and i have changed the oil twice. To break it in correctly. Its as if i lost the half the power when trying to drive it. What could it be? What should i do?
You probably have a govener on it ! This is usually a arm that comes out from under the flywheel it has a spring on it ! You need to fix it solid so the motor does have the timing retarded at full throttle ! It has full power taking off then slowes down ? That be govener !
oh if you have a cvt belt drive you may have your rear clutch getting stuck or problem with front cltch or variator also ! is yours belt or chain drive ?
I’d get the 100 big bore kit n slap it in there or the 80cc kit ! Get cylinder piston carb n pipe usaly less then $200 if you scooter is older get a belt also ,
You may need to check your drive train also rear clutch is working properly if it sticks you can have issues! How old is scooter how long have you had it n when did this all start is important also if I can help
@@WaldensWorld got the bike a weak ago. It ran for the first day and then it failed. I’m new to this. I don’t know how to check the drive terain and idk what is a rear clutch. My rpms have dropped by about double and i need to shift gears much sooner
What about my 50cc kymco 2t scooter? It's got good take off speed and short climbing and 50mph top speed. But when climbing a long hill it gradually drops to 20 or even 15mph. It feels to me it's got the power to do an extra 10 mph in the long hill climbing but.... how?? Cheers for any help.
You can try a bit lighter rollers in the variatior ! Kymco is a good scooter ! Now I don’t know what hill grade your climbing ! You may loose top speed with better hill climbing !
Thanks. The hills I'm referring to are like 15 to 30°. Since no way to downshift I think the scooter would benefit from being able to keep RPMs higher. I'll first try a bit lighter rollers that you said and what about a bit stiffer (+1000 rpm) contra spring?
@@user-ui2js6zx2t it’s the plastic cover over the engine head ! Let’s air flow from right side flywheel fan to left side ! If you haven’t taken it apart it’s prolly ok !
Not much you can do they have rear gear sets the get more speed they have to be pressed into bearings but you can check that out rear gy6 gears I bought set on eBay
I just put a clutch and variator in mine slow taking off and only goes thirty what needs to be done I'm gonna take the three weights off but what else it was going fast with a screwed up variator I mean the rollers were tore up
I think your scooter has been sitting in the I've been putting new shitt every chance I get when I have money now it's only one about 30 it don't bog down no more when I take it's slow take what can I do
If it’s 50cc it only goes in the 30s but you can put a heavy spring in back clutch so rpm is higher before it starts to grab it will give it more torque
This is great info... All the comments are great too. But I wish you guys would use punctuation and structure sentences properly...it makes it almost impossible to decipher and understand what's actually being said, thereby making mods very tricky....hoping I understood what was said.

Makes me so mad to see videos of people trying to make there scooter go more than 44 mph when I owned to scooters one would go 50 the other 55 stock somebody tell me did the change the motor design to go slower
Yes top on 50cc is like 35 40 if your lucky ! Variators are designed to restrict the fun ! ! There are ways ! But I've also seen fools who don't need anymore than a stock one ! Be safe my friend !
They just restricted the power for licensing. Mine is (unrestricted)So you need a motorbike licence! my mate has same model (restricted) you only need car licence
well i've searched and searched and im hoping someone might be able to help on good ol youtube. my scooter will not run properly with all 6 weights. my mechanic installed only 3 of 6 and it seems to run pretty good now. could not make it up a hill with all 6. any ideas scooter people???
Is belt wore ? Is the variator pin wore ? Is compression low ? Are the weights have wore notches . Is the back clutch sticking ? Is your carb clean airfilter clean ! ?
@@WaldensWorld not a mechanic myself but as far as i know... the belt is brand new, variator pin is good, not sure about compression, brand new weights, new clutch springs in back, carb and air filter clean. was running fine with 6 dr pulley weights before replacing with brand new roller weights. then had to take 3 out as it wouldnt go up hill
@@WilSho if the weights are to light it won't hit top speed just be torque monster ! If your carb has adjustable needle pull top of carb cap off pull spring out n needle adjust needle down one notch this will give a richer fuel mixture try that don't get any carb cleaner near boot ! If boot is ripped that will effect it also !
@@WaldensWorld ya i cant go top speed with 3 weights but at least i can make it up a hill. I will try the carb pin and see if that helps too. Thanx for your help

Not sure what your trying to say but I’m just modifying the roller to have more torque there is nothing wrong with the scooter! This is a free way to do it !

Look into a 100cc big bore kit few hundred dollars but will make a huge difference ! If you needle in carb is adjustable try moving the clip down one notch take the screws off top of carb remover rubber boot n get needle out some are adjustable some are not ! Ps don’t lose clip do it in area free of junk invade you drop anything! Let me know how it goes
@@WaldensWorld thanks bro ill try the needle trick and on christmas try to buy a 100 cc do u maybe have a website for it
I have a JAGUAR-200 (169cc) DELUXE Go Kart, Single-Cylinder, 4-Stroke, Horizontal Type, Air-Cooled. I noticed it no longer goes into higher RPM. I dont know much about these engines. What i did notice when i first bought it was it had 3 levels of RPM- power(according to how loud it got when driving it. It no longer goes into "lvl 3" aka the louder more power RPM. It only has 37miles and i have changed the oil twice. To break it in correctly. Its as if i lost the half the power when trying to drive it. What could it be? What should i do?
You probably have a govener on it ! This is usually a arm that comes out from under the flywheel it has a spring on it ! You need to fix it solid so the motor does have the timing retarded at full throttle ! It has full power taking off then slowes down ? That be govener !
@@WaldensWorld i dont think its that. When i first got it the thing would go faster. Now its as if it doesnt go into the last gear.(its automatic tho)
@@madbroindustries is yours a lawnmower based engine ?
@@madbroindustries check air filter n exhaust are not clogged ! Good spark plug n good fuel ! ?
oh if you have a cvt belt drive you may have your rear clutch getting stuck or problem with front cltch or variator also ! is yours belt or chain drive ?
I have a derbi senda 50cc 2003. The acceleration is extremely slow, can’t go up hills, only goes if i push it. What should i do?
I’d get the 100 big bore kit n slap it in there or the 80cc kit ! Get cylinder piston carb n pipe usaly less then $200 if you scooter is older get a belt also ,
You may need to check your drive train also rear clutch is working properly if it sticks you can have issues! How old is scooter how long have you had it n when did this all start is important also if I can help
@@WaldensWorld got the bike a weak ago. It ran for the first day and then it failed. I’m new to this. I don’t know how to check the drive terain and idk what is a rear clutch. My rpms have dropped by about double and i need to shift gears much sooner
What about my 50cc kymco 2t scooter? It's got good take off speed and short climbing and 50mph top speed. But when climbing a long hill it gradually drops to 20 or even 15mph. It feels to me it's got the power to do an extra 10 mph in the long hill climbing but.... how?? Cheers for any help.
You can try a bit lighter rollers in the variatior ! Kymco is a good scooter ! Now I don’t know what hill grade your climbing ! You may loose top speed with better hill climbing !
Thanks. The hills I'm referring to are like 15 to 30°. Since no way to downshift I think the scooter would benefit from being able to keep RPMs higher. I'll first try a bit lighter rollers that you said and what about a bit stiffer (+1000 rpm) contra spring?
@@user-ui2js6zx2t yes or 1200 or 1500 but this will increase wear to engine ! Make sure u got good cooling shrouds connection
Thanks. Can you please give me some more info about this cooling connection? I live in a hot country too :-(
@@user-ui2js6zx2t it’s the plastic cover over the engine head ! Let’s air flow from right side flywheel fan to left side ! If you haven’t taken it apart it’s prolly ok !
What size weights was that
Not sure honestly I didn’t weigh them ! Mabey 14 grams
Will doing this cause any damage later on
No not taking three weights out ! Your fine ! You f you had different sized weights it would !
Can I do this on my 50cc scooter
Yes you need a impact to get the nut off !
Bro i have a Suzuki access 125. I want more mileage. So what i can do for that
Not much you can do they have rear gear sets the get more speed they have to be pressed into bearings but you can check that out rear gy6 gears I bought set on eBay
Bro, what if I increase roller weight. Does it cause any damage in engine or any parts
I just put a clutch and variator in mine slow taking off and only goes thirty what needs to be done I'm gonna take the three weights off but what else it was going fast with a screwed up variator I mean the rollers were tore up
I think your scooter has been sitting in the I've been putting new shitt every chance I get when I have money now it's only one about 30 it don't bog down no more when I take it's slow take what can I do
The old clutch though that password like knew I should have 200 clutch on there huh just change the variator huh
The clutch pads not password lol typo
Please help
If it’s 50cc it only goes in the 30s but you can put a heavy spring in back clutch so rpm is higher before it starts to grab it will give it more torque
Did u notice that the top speed dropped to half?
Lost a bit not sure how much !
sir lm philipine hw to stol bilth..
Nah this the kinda guy you pay to work on your scooter to get it back with a blown engine
But yet it comes not running n leaves running better than before! Nah you a meme! Mr unknown next
This is great info... All the comments are great too. But I wish you guys would use punctuation and structure sentences properly...it makes it almost impossible to decipher and understand what's actually being said, thereby making mods very tricky....hoping I understood what was said.

@@WaldensWorld 🤣😂🤣👍🏽👍🏽
What weights should i get for hill climbing and at least 40mph
5 g
@@williamr3151 do i use all 6
Are you on a 50cc or what and kind of hill. Need all 5 to apply enough pressure to grab the belt going uphill yeah
@@WaldensWorld yes a 50cc ok ill give it a shot
Makes me so mad to see videos of people trying to make there scooter go more than 44 mph when I owned to scooters one would go 50 the other 55 stock somebody tell me did the change the motor design to go slower
Yes top on 50cc is like 35 40 if your lucky ! Variators are designed to restrict the fun ! ! There are ways ! But I've also seen fools who don't need anymore than a stock one ! Be safe my friend !
U probably have a japanese scooter..theyr the best.
I designed the whole concept on these weak scooters and i got to find all the power hidden in them.
@@toneburgos5190 check out my Honda elite stroker I built it was a wheelie machine almost 70mph stock it prolly went 35, mph spent like $1200
They just restricted the power for licensing. Mine is (unrestricted)So you need a motorbike licence! my mate has same model (restricted) you only need car licence
well i've searched and searched and im hoping someone might be able to help on good ol youtube. my scooter will not run properly with all 6 weights. my mechanic installed only 3 of 6 and it seems to run pretty good now. could not make it up a hill with all 6. any ideas scooter people???
Is belt wore ? Is the variator pin wore ? Is compression low ? Are the weights have wore notches . Is the back clutch sticking ? Is your carb clean airfilter clean ! ?
@@WaldensWorld not a mechanic myself but as far as i know... the belt is brand new, variator pin is good, not sure about compression, brand new weights, new clutch springs in back, carb and air filter clean. was running fine with 6 dr pulley weights before replacing with brand new roller weights. then had to take 3 out as it wouldnt go up hill
@@WilSho if the weights are to light it won't hit top speed just be torque monster ! If your carb has adjustable needle pull top of carb cap off pull spring out n needle adjust needle down one notch this will give a richer fuel mixture try that don't get any carb cleaner near boot ! If boot is ripped that will effect it also !
@@WaldensWorld ya i cant go top speed with 3 weights but at least i can make it up a hill. I will try the carb pin and see if that helps too. Thanx for your help
watched the first 10 seconds and almost got motion sick. No content for me...
Take so me Dramamine n come back lol sorry some I do on tripod with nice camera just depends on what’s going on !
Glupost. Šta hoćeš da kažeš? Da se moped pokvario tako da su rolnice postale teže? Očigledno je da problem nije u rolnicama nego u kvačilu. Verovatno je pukla opruga kvačila a nju nisi ni pogledao.
Not sure what your trying to say but I’m just modifying the roller to have more torque there is nothing wrong with the scooter! This is a free way to do it ! You can buy lighter rollers and have 6 to achieve same results you can buy stiffer clutches springs to take off at higher rpm to also help with torque! Thanks for watching! This is just a free way to do it
