CVT belt rise vs clutch depth  By  gy6fandan (Read 2,350 times)

It also depends on the Variator not all Variators are the same most of them the ramps are cut to give you good low and mid-range but you will never get the belt to climb near the edge. Now the Prodigy Variator is a good one for top end due to the ramps angles and the pulley face surface. You bottom end is not as strong but it will push the belt high.
Here is my prodigy variator notice the mark 1/8 from the edge and that is a 115mm variator with 12 gram Dr Pulley Sliders.

what pulls it apart, i dont know if you read my post about the belt, before i editted it. is, the width of the belt. if the belt cant bottom out then maybe a skinnier belt at around the same length, and use the same v- angle. woudl work. to max it out.

waht i was sayign let me summ arize all that. try a big downhill. heavy up your weights. then drop down that hill. since you cant tell what at what rpms or speed or mph you need to shift at, to get the best running transmission. so cheat on everything. mark ure variator, heavy the weights up some. depending on what biek you got, 50cc 150cc. 250cc. so many or whatever however many grams. and use that hill to see if your maxxing out your variator then. if its not maxing on the variator, then the belt, if its not fitting like a globve may, bottom out, in the rear driven pulley. then not pull any farther up the front, drive pulley, cause it can't.
but get the right belt. then if it wont max, then theres something else going on. if its a, lemon, or stock restricted like my scooter. .. better hope they dont figure that one out. what solved that for me, is an aftermarket variator. since it is the deciding thing in how far your belt will give you more speed, as the cvt shifts.
so. front drive face decides how far you shift. thast how i figured out i had a variator restriction built into, my stock variator on my bike. i found out what it is too. another thing that helps to shift up higher, dr pulley sliders. but use them on an aftermarket variator. when you find out what is keeping your scooter from shifting up. if your belt is slammed, down in hte back, and doesnt fit on likee a glove. if its, real tight like extra tight. and theres a bigger betl. try it. but also, cheap belts can have slackin them. try some good anmed belt. how do you know the right size? if others have brand new ones. and they came with one that fit, like a glove. and measured it before they rode it. thatll give you the measurement. of thelength. outside. the actual number they give you, is the inside measurement of the length. what keeps them in the oem spec or measurements for the belts, like a 669 or 842 or whatever measurements they are, is a good brand, .. thats about all. or luck. so even an 832 or a 842, say you get one smaller and if its got slack, then it might be closer to an 842. or whatever. these are just nubmers im throwing out there. i dont know what im saying.

mrp speed is a good company i think on making belts. close to oem specs. you want tight but you dont want overtight.

i believe this guys deal might be his belt could be a smaller belt than it needs. or maybe its some to light rollers. maybe its a factory restriction, hidden. if you cant get it to shift down by checking the front, yuou should use heavier rollers, and a big hill. that wont work or u cant do it, use a marker and measure if itll stay on there. on the bottom of the rear pulleys, halves. if your light on roller weights too. itll sound like your overrevving. maybe thats it.
