Variator Weights Misconception QUICK TIP - Somewhat Daily Stuffing

"Try not to Become a man of success, but a man of value" That's the truth Thank you for that random motivation

[@mtabby1]

That one sentence has made me subscribe... I accept this challenge...

[@miket.220]

So basically, the rollers perform the same function in a cvt that sprockets perform on a chain-driven bike. Lowering or raising the tooth count of the sprockets on the bike won't give you "more" top speed or acceleration, it will simply work differently with the engine/rpm band and you'll trade one for the other, depending on gearing. Different weight rollers will keep you in a certain 'gear' longer or shorter as your engine revs. Which is 'better' is dependent on how you ride the bike and where your engine likes to operate.

[@ZCRAIZED1]

Incredibly well stated. That is exactly what the variator does. If it's viewed as this analogy it should be thought of as a person with the ability to exert X amount of force to the bicycle crank at a range of rpm. The same work being done viewed as calories expended and muscle worked\torn. Hypothetically a person can pedal faster with less force to get to and maintain 20mph or pedal slower with more force to achieve the same result. Operating in a reasonable range of the ability of the person\powerplant\ engine, it will end up at the same top speed eventually as long as the parameters are within a good range of specification.

[@inveimer2015]

good explaination.. people forget that the variator spin on the crankle.. modifing weights and change with a more performance variator is equal to lightening a flywheel. higher rpm without a correct calculation isn't a good choice, risk of overspeed is dangerous. remember.. at high rpm the torque.. decrease.

[@ruudiutsenikov609]

thank you so much i was gonna buy lighter weights (im actually a biker never ridden a scooter) but i just wanted to check if you had any videos and you did and i figured out i need heavier weights

[@levitezoe1804]

Finally thank you so simple yet people make it so damn sophisticated

[@williamvolkmann8658]

15,000rpm if your turning those kind of numbers your not gonna watch this for advise you are spot on as to light weights shift at high rpm and heavy shift quicker what makes the decision is how much weight are you hauling off the line

[@DivergentDroid]

A light rider, say 110 lbs.. heavy or light weights? I actually wanna make my 150cc scooter Slower Less Powerful to learn on. Perhaps I should have started with a 50cc but I didn't have that option.

[@rustyboy57]

I installed some sliders 11g with a racing variator , i found i accelerated much quicker and got to 46mph pretty fast, however i do now find that i struggle to get to 57mph which is what i got on stock, but i think it is because i have a lighter weighted variator and the rollers are now sliders producing better acceleration at the cost of top end speed.

[@oela.suriname]

I have a jog90 variator on my Keeway scooter with a 70 cc malossi set up. The clutch is original. Malossi wild Lion exhaust. I had tried 4 gram and 5 grams weights. also a mix of 3.5 gram with 4 gram. still the scooter had a slow take off. When I switched to full 3,5 gram weights everything changed. fast take off. Good speed. 80km/h. I think i can higher topspeed. So, lighter weights with a heavy variator can mae a difference

[@giwtwm]

when the rpm drops as you take off as you wack the throttle the contra spring is too soft

[@VisitaInteriora]

hi, my 100cc Bali can't go into high rpm when I am standing on an uphill slope. It drivers too slow for at least 20m. I used lighter weights but, the problem persists. As soon as I get higher rpm, the the engine and variator run ok. Don't now how to solve this.

[@danguy2009]

I see this all too often in a few Facebook groups I use. I get sick of explaining it haha.

[@t2618-z8i]

Ok so what weights will i use to gain speed from acceleration and top speed?? Please let me know

[@t2618-z8i]

Can i keep the stock clutch if i upgrade my variator also do i need to get a different drive belt or can i still use the stock one

[@Dwainpipe21]

the roller weights that are put in as stock are a compromise , you don't necessarily want a scoot that instantly shoots up to 8k rpm ( peak power) as soon as you fart on the throttle when trying to cruise along At 50 mph an a straight road or through town on a slightly open throttle lol.Its fine if you want that sort of performance ( I know some will)but most that think they do probably don't when they are trying to commute into work in the rain !. Not meaning to be a killjoy just saying think about what you want to achieve before you go fiddling and end up with undoubtedly a faster scoot but maybe one thats crap for day to day use. I can never understand why people think putting heavier weights in the variator gives better top speed it can only ever close up so far and unless you put stupidity low weights in it or you fit a spring that is way too strong it will always close up as far as it will go giving the same top speed.

[@giwtwm]

this is my problem now, normal casual takeoff takes 6000rpm to get the bike going its a pain in stop and go traffic lol i will try a heavier rollers

[@giwtwm]

actually there is another factor (RPM) regardless of pulley belt travel, as the belt reach the top of the pulley the bike will now accelerate as the engine RPM increases lets say if you put heavy roller and your belt tops out at 7000rpm and it cannot go anymore faster but when you put lighter rollers your belt tops at 8000rpm and the engine produces a bit more power at such rpm the top speed will slowly creep up together with the rpm a 500 rpm increase at top belt travel could mean 10-20km/h more speed

[@MR-jw3bq]

What about 8 gram roller weights would that be too heavy?

[@ianlanford6922]

i have pcx 160cc engine. peak at 15.8HP at 8500rpm. it has bigger engine but also heavier bike. at 131kg. with fuel 8.1liter. and oil etc. it will be closer to 140kg. make power to weight ratio even worst. it has 19gr roller. i think it pretty much self explanatory. very smooth acceleration but also quite a heavy drag. ill try 17gr roller soon.

[@ancient.journey]

So what need to do you can jump lights like rabbit? Bowl?

[@martinst.andrew4026]

OK I was running 6.5g in my scooter 49cc with a big bore 100cc kit could not get it over 40. I put 8.5 in it that came with my kit and now I am hitting 46miles why is that ?

[@2STROKESTUFFING]

The 6.5g weights were probably not enough to push the belt all the way out to the edge.

[@Torquer]

Went through all the comments and I am still confused. I don't care about top speed (it is limited to 25km/h anyway). My used scooter revs very high before the stock clutch grips and start moving. I want the clutch to grip at lower rpm for low speed cruising/traffic. Do I need to go for heavier or lighter weight rollers?

[@ElEspecialistaAr]

[@rosstempletonogskater]

I got a rebuild kit w little bit heavier weights & I put them in. The engine was constantly winding out, too high rpm before catching, not using ANY of the lower rpms, very annoying. I put the stock lighter weights in & it was much better use of low & high rpms. So the heavy weights made it rev all the time. Yerf dog 150cc

[@sonyyoung1036]

Please elaborate on what you mean at 1:10 when you say 'keep the rpm at peak power while the bike is variating". In your example, you use 15,000 rpm so does that mean the bike shifts when that rpm is reached? How can you identify when the bike shifts with a CVT transmission? Thanks

[@elpepe7658]

im probably a little bit too late and you know this stuff already. But what i have learned the variator starts to change the gear ratio for example at 15,000rpm (which isnt quite realistic) or where ever your bike makes the most power and it keeps the RPM constant through the range until it hits the maxium "gear ratio" where the belt is in its outer edge at primary variator and at inner edge in the secondary variator. Cvt doesnt shift like a regular transmission so it doesnt have those noticeable rpm drops when it "shifts" but it changes gear ratio when the rpm in trying to get over the limit set by the rollers and contra spring. You cant really tell when the variator "shifts" because it has an infinite amount of possible gear ratios and its so smooth because of that. Its possible that i got something wrong.

[@KentRoads]

My bike is really slow to pick up revs up to around 15-20mph, and then it pulls ok revs fine, is this weights/drivetrain servicing related? Thanks in advance

[@kuyacross]

How do I determine the peak rpm? And which weight does keeps it say at 15k rpm

[@whyalwaysme1106]

1) check google for your bike specification 2) your scooter dont rev to 15k rpm

[@1960ARC]

I bought weights from my Vespa dealer. I put them in and my bike is slow going up hill. I can't remember what colour they are. Yellow or green. I think I took out yellow ones and put in new green ones. I want to replace them, but don't want to get the wrong ones again. I have a 2014 primavera 125. I thought the new weights felt a little heavier, than the old ones, but I'm not sure which Colour the new ones were, only that they are green or yellow?

[@itslaika8745]

Change roller or contra spring first for fully standard scooter?

[@Mr.frever]

I have speedfight 3 70cc please tell me which rollers

[@billyhope3533]

Will lighter rollers make the torque peak sooner?

[@Sidg2]

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.

[@jalanihidup6119]

No, it was prohibited. Grease only need to be added on the driven face iner part and the 3 pins

[@benredding7080]

Maybe, grease is OK to use in racing or other scenarios where the variator will be cleaned frequently and the dust isn't allowed to accumulate. The belt produces a fine dust as it wears. Grease will attract and cause a build up of belt dust in the variator ramps over time.

[@nanzansarcade]

Heavy rollers and light clutch. Is that good combo?

[@cheedam8738]

​@@nanzansarcadeYou gotta try out whats best for you. But that combo isnt bad

[@iamakkkshay]

​​@@nanzansarcade You will get low low end torque as the wheel will start moving early at very low rpm but good for efficiency in traffic as you can then set your idle rpm to very low if your engine doesn't stall when running decently hot.

[@nanzansarcade]

@@iamakkkshay so if the scooter comes to stall than if I accelerate a bit more it won't stall anymore right?

[@jjack4230]

"become a man of value": much commented already. Thank you for showing the way

[@SegaDisneyUniverse]

I don't remember if my scooter had light or heavy rollers put in. But 2 months ago I had my 49cc scooter upgraded to a 110cc, but before I was able to reach 50+mph going downhill but only 35 on flat ground. Now with this engine I can only go 45mph on flat ground and downhill, and just over 30 uphill. Do I have light or heavy rollers?

[@FutonStories]

You have heavier rollers that do not accommodate your engine upgrade. Experiment with lighter rollers to boost your engine RPM and keep the engine within desired power-band. Thanks.

[@benredding7080]

Your mechanic lied to you.

[@giwtwm]

My experience regarding upgrading scooters the bigger the engine upgrade the lighter the rollers and stiffer the contra spring, it just produces so much power and so fast that the roller weight shift up the variator too soon actually making the bike slower than stock

[@jamesbraun7709]

I put in 20 gram rollers , no other changes at this time . I do want totry Dr. Pully sliders at 20 grams . Maybe I will need a bit bigger spring on the rear variator . One step at a time . For racing ? No ,for normal use and pulling a cargo trailer .

[@ebunnes]

I changed 5,5g rollers for my chinese 50cc (gy6 engine) and now from standing start the engine revs quite high before the transmission "catches" and then the rpm gets lower and rises gradually as speed increases. This revving didn't happen with the old rollers but the RPM just increased logically from standing start. Now my question is: could this revving start cause damage to the belt/clutch or the cones so should I get slightly heavier rollers?

[@alias6811]

Maybe try 6g

[@ramiretz]

choose the weights where to most Torque is or where the most HP is ?

[@mociczyczki]

acceleration and topspeed = hp for lower fuell consumptionless noise = lbf ft

[@ramiretz]

👌🏻👌🏻👍🏻✨

[@mastodonttix]

But should you aim for peak torque rpm or peak hp rpm is the question, for example vespa 250 gts has peak torq at 6500 and peak power at 8250

[@2STROKESTUFFING]

Peak power rpm. You'll need a clutch that grabs up there though, otherwise the variator will get stuck at lower rpm.

Whan you upgrade to a big bore kit does this change the power band drastically or or will it be relatively close to the same as the powerband when the bike was stock? I have been tuning my scooter with an 80cc bbk on it and it's been tough to decide on what sliders to use in my Dr pulley variator. With 6gm sliders I can reach 8000 rpms downhill and with 6.5gm I hit Max of 7400 rpm. What rpm would you say is to high and most likely skipping over the power band for a 139 qmb 50cc 4stroke? Any input would be greatly appreciated Thanks in advance.

How would I go about finding the RPMs of my scooter? I'm new to this all and feel lost at times. What are some recommendations for increasing overall top speed? I can get my scooter up to 35 mph; however, I would like to reach 50/55 mph. Any website or channel recommendations for beginners?

[@Roma-kg9ld]

If you want a higher top speed, the only one of the changes listed that will affect it is changing the stock exhaust to a performance exhaust, and even that will only have an effect on the top speed if you don't have an RPM limiter and a better exhaust allows your engine to reach higher RPMs. Do the RPMs start to rise when you are nearing the top speed? If yes, it means that you'll have to get a new variator that allows a lower gear ratio, basically it will give you an extra gear or you'll have to raise the max RPMs. If not, it means that you'll have to increase the engine power at the RPMs it's running. This can be achieved by checking whether it is running at it's peak power and if not, adjusting the roller weights to fix it. If it is running in it's peak power, you're going to have to do something to your engine to make it produce more power.

[@ib9459]

I have an elystar 50cc , what rpm does this scooter makes? I bought it cheap used and needs new transmission

[@goru426]

This is very confusing to the every day rider and the way it was explained is also very confusing. Most scooters come with heavier weights in order to maximize fuel economy and engine longevity. So by default they come with the wrong slider/roller weight. So if you change them to lighter weights you will put the engine in it's power band sooner and you will definitely get quicker acceleration. This video does nothing but confuse people and it should have been much longer with better explanation.

[@Surroundnutz7107]

So basically lighter weight make ur bike launch faster and heavy weight give top speed. He said that isnt how it works but he explained it that way? So im confused.

Top speed isn't affected by roller weight as long as the variator is able to "gear out" fully.

Mine's a 125cc Yamaha. 11grams roller weights, 4s1m racing pulley and drive face, stock clutch spring (800rpm?), and 1000rpm center spring. It revvs somewhere in the mid to high range and gets a top speed of around 100kp/h (around 62mph) easy.

what grams may I use if im am 90kg and my backride is 80kg...may stopspeed is 80kmph and when uphill almost 40/50kmph.im using 12gx6 of roller.it's very slow.tips how it work for best

[@2STROKESTUFFING]

Impossible to say, sorry. Every setup is different, you'll have to experiment with lighter/heavier rollers and see how it reacts.

[@brainfixertv2358]

thank you...I'll try...good job...:-)

[@2STROKESTUFFING]

Thanks!

6x6 or 4.5x6 would be for full time dual riders

Ok so what weights will i use to gain speed from acceleration and top speed?? Please let me know anyone

[@hamzaanouar]

As he said the top speed will be the same The lighter rollers will make the scooter accelerate faster

[@mitorider1365]

@@hamzaanouar In extreme case's, If you go too light with the rollers it can effect top speed because there is not enough overall weight to push the variator together. Too heavy and it changes 'gear' too quickly and the engine cannot pull the gearing at low rpms.

[@pistolerongpinoy4893]

Hi if i change my contra spring to a stiffer one like 1500rpm..should i replace the rollers with less weight or use heavier rollers?i was using 1000rpm contra spring before and using 10g rollers

[@2STROKESTUFFING]

Don't change the rollers and see how it behaves, if not to your liking go lighter/heavier.

[@pistolerongpinoy4893]

2STROKE STUFFING thanks will try 10g rollers again..

[@pistolerongpinoy4893]

Currently using the 9g rollers. Take off is good..but too long to hit 100kph

[@MREVERYTHING8]

@@pistolerongpinoy4893 try 8grams roller and 1000rpm center spring.and don't change the stock clutch spring . It will make it fast to accelerate and achieve early to ur top speed and less vibration ..

[@marioraja4229]

i love the somewhat daily stuffing videos. So if you put heavy weights on then you will have the same top speed, when you use the lighter ones?

[@2STROKESTUFFING]

Thanks! Yep, as long as the variator can gear out fully - too light and it won't.

[@marioraja4229]

i also like the end quotes :D

[@giwtwm]

​@@2STROKESTUFFINGactually it still can top out as it just takes more RPM to create that centrifugal force ,my crazy friends tried removing 2 roller weights in a 6 roller setup, only 4 was installed and the lazy scoot transformed into an rpm monster with loads of acceleration i marked the pulley and the belt still tops out the rpm went up from lazy 8000 to 10000, 4 stroke scoot

[@emanuelwilfred4635]

Sir I have 4 stroke 150 cc scooter BT top speed is two seated is 80 plzzz sgest better rollar and what gram plzzzz sir

[@gypakos1]

Hi i have i majesty 400 2007.put reicently half 14gr and 16gr.Magnificent accelleration b0 100 10sec but 150total speed.. was 165 what did i did wrong??put also a white sping

[@churcher8334]

You are running out of peak revs to obtain maximum revolutions on the wheel.

[@albinnilsson3127]

Jävligt bra och tydligt förklarat! :)

+Albin Nilsson Takker!

[@somaaa5554]

Okay so this is whats happening: I have Beta Ark it's 3.2kW...with everything stock it goes around 80km/h with me(66kg)...but acceleration is shit and i cant possibly pop a wheelie...do you have any sugestions what should i change to get a better takeoff?

[@2STROKESTUFFING]

Try lighter weights and see what happens, it might running too low in the rev range.

[@2STROKESTUFFING]

And stiffer clutch springs too, if the lighter weights help.

[@somaaa5554]

2STROKE STUFFING thank you

[@johnjonn966]

Hello thanks for the information its very helpful and informative, if you have time I have a few questions about the torque driver and I would like to know if you can help?

[@davidduque3956]
