ATKS-04018 18x14mm High Performance Racing Variator Roller Weights Set 152QMI 157QMJ GY6 125cc 150cc Scooter Moped ATV Go-Kart (10 gram)

Just put them in. They fit. They work ok. We'll see how they hold up. I got over 20,000 brutal miles out of the glixal polygon sliders in an all out race motor. Perhaps these will hold up to the punishment those did. I don't care what color they are or how they look. As long as they are durable.

desde que le puse estos rodillos de 14 gramos mi scooter 150cc va mejor, mas suave despegue regular pero mas potencia en el trayecto, recomendados!

Bien

I had 17gram weights then mixed these 13z half and half with 17z and comes out to be 15gram weights... Was actually perfect. Didn't lose top end and gained a considerable amount of acceleration. 5 stars

Marketing hype, baloney, etc etc will make one believe you best cough up the bucks and buy the (expensive) big name sliders to boost performance. That is a lie, I'm calling them out. Once a variator is closed you are in the highest ratio possible and speed is wholly determined by engine rpm and if it has the power to pull it. Closed is closed. The flat sections on a slider are like false gear changes where you experience steps which are not a smooth transition as it crests each sliders apex and moves over it. The ramps in the variator are a smooth arc. The plate is a flat contact point. You will tune (select weights) on what you want to achieve. Quick acceleration or a cruising machine. You will not achieve the best of both. Too light and you go straight to a closed variator. Too heavy and it remains open. You will chose something in the middle ground. The medically named sliders are a ripoff plain and simple but they have great marketing. I spent a lot of money tuning with them (you must tune with whatever you plan to use) and returned to the roller. Round, follows the smooth arc, and presses on the flat backplate as any will. The contra spring? Start in the middle. Clutch? start in the middle. If contra is wrong you'll end up at one extreme or the other in weight, only then change. Clutch is a matter of personal feel. Need to move in parking lots? Go light or middle. Want a launch? Try the stiff side. But only when everything else works. BTW, if you change engine performance you will likely be changing CVT tuning as well, know this. So don't get ripped off as did I in the learning curve of marketing hype. And wear? So what? You will need belts, right? Change them all at the same time, always have fresh smooth ratio changes. Four sets of these rollers to one of those sliders, do the math. Yes, the sliders will feel different and give a different sensation, yet they cannot be more smooth in transition tha a round roller following a smooth arc. CVT tuning is a learning curve. One change at a time. Stay with whatever you intend to use. Keep everything clean. BTW, I weighed my 12 gram rollers and they were all exactly 12. Were the expensive sliders all exact? No they were not. I do suggest you but a gram scale. Half a gram between the heaviest and lightest is the max. If you have deviations mix the set, i.e. don't place all the light or heavy ones on one side of the variator. Again, do not fall for the hype, and it is very convincing. Overall performance is rooted in power to weight ratio, know this, you canot change physics. I could write a large article. I hope there was enough herein to save you a lot of money and get to the the performance you desire for your particular use.
