Thanks for explaining the variator roller position, was checking out for this video for along time. And was clearly explained 👍. People on TH-cam keep confusing by setting the rollers the opposite direction of what you mentioned and some saying the coloured sides facing eachother.
Great video!! I have a Yamaha Rhino 660/Hisun 700 and this should apply for them as well I think. I’ve never heard anyone talk about which side should go where. Thanks!
Hi great video. I used NCY 12g rollers and managed to get the bike up to 52mph. But at the top end speed I’m getting a vibration, any thoughts on why? I did notice the 12g rollers have different looking sides on them. Do you know if they all have to go in the same direction? Rollers did not come with any directions and can’t seem to find any information or videos on it. Thank you
actually this might be wrong! the stopper side (each roller has 'open' side and stopper side -red in this case) should be on the OPPOSITE of rotation direction, at least according to dr pulley and kymco factory
metal side leads in clockwise direction -simplest, so if you imagine variatior as an old clock at noon metal or open side would be right, but at six it would be left, always leading in clockwise direction
HI MATE I DONT KNOW THE ORIGINAL WEIGHTS WHATS IN 50CC DIRECT BIKES MOPED AS WHEN I TRY GET UP BANKS ITS ONLY DOING 20 MPH SHOULD I TRY THE LIGHT ROLLERS IN SAY 5.5 THANK YOU.
@@johnwhite3346 you probably already got it fixed now. But, you would need a variator holding tool or impact driver/wrench and a scale. Take the variator off and weigh the rollers. Go lighter for more rpms and better acceleration but possibly lower top speed.
@@krollpeter I took out 3 rollers and put in"3"- 6 grams in the right order and it improved my uphill torque and near the higher end in speed....experiment a little with 3 weights
@@russbraidwood7416 Thanks for responding! I can well imagine that it may change a lot, in particular with some smaller scoots. Sort of adjusting it to the local riding conditions and rider. I tried each 1 g less, Dr. Pulley sliders, not rollers. It did improve a little the pull from 10 kph to 70 kph. However, I'm back to stock. Reason? I found my Sym 170 cc is with passenger equal or stronger than most others of this class solo. The top speed not, but acceleration. It seems mine is very well tuned from factory. For others it might be well worth a try, since it's low cost tuning.
In gearless scooters, Should we apply greese or wax 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.
The repair manual does not call for any lubrication of the rollers, so that is the advise I follow. As to the reasons why, I can only speculate - no need to reduce "friction" there, or perhaps unwanted oil contamination... I had no problems with rollers for tens of thousands of miles without any grease.
@@john21031 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 No. Dr Pully has flat "rollers" which are designed to slide. You don't put grease on them the same way you don't put grease on your tires or transmission belt. They are already round and designed to roll. Gripping is no problem for them so grease in completely pointless.
Nice information sir, should we greese the rollers or not,I'm bit confused about the greesing of the rollers because some mechanic uses greese and some of them are not using it, so plz let me know about this
Hi frnd. I have a problem. My scooter 110cc same variator & roller as see in your video. And my scooter vibration on 40-60 speed l, not feel Smoothness. Will. You have any ans.?
Either from the wheels (bent rim or bad tire) or if the vibration comes from the engine area, you might have bent variator or clutch or the piston is damaged. Take the variator cover and run the engine, see if anything is vibrating. Good luck.
Its not always like that !!! . BMW C650 the side with the thin edge faces towards the low sidewall in variator plate. So I am assuming your way is only if the variator plate has the same heights sidewalls as the video shows. I recommend always check the specific bike manual first.
I use stock rollers and believe that it's the best choice because the variator works best with the stock rollers. I don't know what will be the result of you installing different roller sizes/weights, I wouldn't recommend it.
The exposed metal roller wears out the softer aluminium ramp side eventually causing the rollers to dislodge and jam often resulting in a stuck in high gear situation.
Clean them well, no grease. You could however clean the sliding surfaces with a damp WD40 cloth. No misunderstanding: do not leave WD40 there, just clean it buy rubbing a bit with WD40.
It's not wrong, placed the wrong way the inner metal sleeve can slide out and cause damage to variator or get stuck in it's place. It happened to me back in the days
You are the only person who clearly explained the correct orientation of variator Rollers of Honda Activa. Thank you
same, i think that would be why mine seemed to wear so fast.
Πάντα αναρωτιόμουν αν παίζει ρόλο πως τα βάζουμε, τώρα μου λύθηκε η απορία, μπράβο σου ευχαριστώ για την πληροφορία.
Very good Information...Which I found out the hard way having to buy a completely new one.

that only means that it really doesnt matter so much, i for one, am having hard time to believe that it matters without explanation why
@@seekter-kafa not much of importance for low powered scooters. for big cc maxi scooters? totally matters.
This is perfect roller weight installation

Great video! Very informative! Thank you!
Thanks for the clarity!
Can worn out roller be reason for slow ride, valve has been checked so there is not problem.
This seems wrong most or not all motorcycle mechanics recommends the more covered side of rollers to be placed on the V shape side of the pulley
What will happen if we put the sided facing each other?
I am planning to put new rollers in my bike and I need to know does this apply to all bikes
my manual says -''color side toward clockwise'' so looks like this video is correct
Do we put grease with the rollers?
so rubber side on the right AT SIX O CLOCK position (cause at twelve its on the left)

You need to know their original weight.

Roler size end waight? Plize tell me
Hi will it ruin my c.v.t. if I ran 3. 9GM. Rollers instead of the 6. 4.5. ?

I tried and come back on this. Now i had installed mine a week ago and it makes noise from there.
If you invert the variator it will run in the contrary rotation of you are saying 🤔🤔🤔

!!big NO!!
Sand particles will stuck in grease and damage the outer rubber layer of the roller.

No
NO
nice video ty bro
Man ,just did the roller change before watching this video

Is that 15grams roller weights?
Light rollers get less speed and stronger. Larger roles get more momentum but weaker in pitch.
Your right.. the rollers will depend on your weight. If the rider is heavy, you need to put lil bit heavy rollers to achieve your own riding standard.
Correct
Mine does not have different sides
Hi
my stock variator roller size is 20x15mm 18g, Can I install 18x14 16g
I use stock rollers and believe that it's the best choice because the variator works best with the stock rollers. I don't know what will be the result of you installing different roller sizes/weights, I wouldn't recommend it.
It should be 20x15. You can however experiment with the weight.
What happens if the rollers are in backwards
Eats up the material faster. In the worst case the bushing of the roller may come out.
The exposed metal roller wears out the softer aluminium ramp side eventually causing the rollers to dislodge and jam often resulting in a stuck in high gear situation.
Good job ..Do rollers be greased or not??
Clean them well, no grease. You could however clean the sliding surfaces with a damp WD40 cloth. No misunderstanding: do not leave WD40 there, just clean it buy rubbing a bit with WD40.
@@krollpeter Use brake cleaning fluid to clean away any grease or belt dust. WD40 residue from rag will actually attract dust. Just don’t
@@drdrew3 Thanks Andrew! I get it, you prefer dry like a fart ...
Nice
what size of roller stock
Very nice
🤝
Perfect
Thanks
Light weight does scooter faster on thunder use 5 gram
Good
👍
Giving wrong information
It's not wrong, placed the wrong way the inner metal sleeve can slide out and cause damage to variator or get stuck in it's place. It happened to me back in the days
Wrong
THAT IS WRONG INSTRUCTION ,
Should we apply some grease to the rollers weight?
It has to be dry
