The first pic looks just like the position of my belt after every time I re-install it (before touching the pulleys and/or moving the belt)
Hope he chimes in when he gets those parts.

if he took pictures and showed the belt like that. itd make you wonder. the marks being up so high, kind of shows, either a belt worn out width or with lots of slack. the marks on his kicker ramp plate and variator. looks like what it would be having black belt marks, with a belt that worn running.
the up down width isnt really measured so much. when finding belts. the width, left to right, like the width of the belt. thinking of it as a belt. like you, wrap around your waist. and the length, then the v angle. of the v-belt. like in degrees. 669 is inner length measured actually, 18 is width side to side, and 30 is the degree of the angle of the V.

I'm still not 100% convinced that a cheap belt alone is the cause of this---although it's possible it's part of the problem.
I guess that's because all the off-brand stock belts I ever had, never even came close to being down to 11mm in such a short lifespan--- 2 months of riding from a brand new ( he did say that right?) scooter, and I ride a lot! Plus that "rust" already on the variator drive plate and outside of the clutch bell, and even a few other places.
I've heard of belts breaking prematurely, but I can't say I've ever read about a belt being wore down to 11mm in 2 months. If so, there must be some horrible belts out there (worse than I thought). I mean that CVT is CAKED with dust, lol.
I mean I understand that a really junk and worn out belt could be the cause alone-- slipping, overheating, wear..etc.

I don't think it's the brand of belt that's is on there either that is causing the problem , if the belt was junk it would have snapped by now , . And your right onewheel , I've never had a belt show that much wear from 18mm to 11mm . I'm guessing the belt has been on there for awhile . There is so much slack due to the 11mm width of the belt that buy the time it starts to catch it's already higher in the variator . And it still slips causing the black mark. When I posted the bando I didn't mean it was the cause of the problem I was just saying I prefer the gates over the bando that is the Kevlar gates because it lasts longer . Bando is still a good brand , they just don't last in my cvt. also I think it's showing no signs of slipping low in the variator due to what I said , the belt isn't even making contact much if any that low .

I got the idea that he had the scoot for a short while and this is the first time he opened the cvt . ?

He said " I've ordered the part new and intend to replace it " ? Not sure what he means ? He also says he is going to order a new belt . He said he bought the scoot 2 months ago and it's been loosing top and low end and this is what he found when he opened the cvt . So I'm not sure if he bought the belt new and put it in then this happened or not ? Either way I'm surprised the belt didn't snap by now . That's a ton of ware!

I knew I should of edited the words "100% convinced", sorry, lol. If anyone was doing any convincing-- it was me trying to convince myself. Honestly, I edited that post like 4 times earlier.

The corrosion on that pulley could have easily eaten up the belt on that side.

the reason i put the direction in which you measure the belt, is cause i was thinking he measured, the thickness. of being 11mm. i cant see a belt wearing off 1/3 of it and not actually ripping first. thats lots of cloth to go through. think he has another problem. thats my opinion, only. like the contra spring in the back maybe broke? it would also not shift right, wouldnt start off in first.
the wear looks like its barely moving up on the variator. like staying in the center leavintg the middle open, to get some corrosion. use a little light sandpaper to fix it up so it dont eat up the belt. and if the back spring isnt workign the belt wont drop in the variator in the front all the way.

Your right he could have been measuring the with from bottom to top instead side to side , I also thought it was very strange it didn't snap before it wore down to 11mm . And also it does look as I the belt is completely skipping the inner variator and riding higher up .

I don't see how the belt didn't wear down to 11mm, with that being a new (new used?) scooter 2 months ago, with all that belt dust. I'm sure it's all over the CVT cover, too. Where else did all that dust come from? Hard to tell if there are any leaks in there for sure.

The corrosion on that pulley could have easily eaten up the belt on that side. To me that would make sense as to why the belt didn't snap after being wore down to 11mm----it only took a beating on it's side (width). |

it didnt wear down to an 11mm width without breaking. if it happenned that quick it would of overheated and broke. or its just such a bad belt, that it wouldnt of made it for 2 months. 7 mm of wear in 2 months. have you ever openned your cvt? after a year? that looks like normal black marks for something rubbing but running on a cvt. running on the bottom or something. having some sort of other problem. the spot its running, showing by the picture and teh black marks. shows hes running in the middle. id ont think the bike would of kept running if it was actually a belt of that size. and it was being ran like that. liek thats where it runs. its also sloppy in the picture. that means it spins to the farthest spot it can on the variator while pulling back, and runs from there. the black spot on the ramps he shown. where the belt drops down in it. its probbably a broken contra spring. somethigns broke. if the contra spring was working it would break it.

Not to be argumentative, but I open my CVT monthly, and I haven't had any black belt marks on my variator at any time.
