Stage6 oversize cvt problem

[redsea]

Hello
I have Yamaha Slider 2002

I have tried to set upp my variator and i have tested weight from 3 gram+6=18 gram
To 5.5 gram+6=33gram and all in between to find something that works.
But i still have about 10 mm left on the front variator and i tested shims different slot angles rear pulley 38 and 41 but no different

I wonder if any one have same problem and wonder if i have the wrong belt
In the manual it says long minarelli S6-591667 belt
And short minarelli S6-591668.
But i bought all as a kit and hoped it should worked out but i cant get the belt all way up
So i wonder if i got wrong belt or any other idea ?
Sorry for the long text
Best regards Steve

is this the belt you have
www.scootertuning.ca/en/variators/7028-drive-belt-stage6-r-t-oversize-4051272255250.html

can you take pictures of your front and rear pulley with the belt on

you should be using the long case belt

[redsea]

Yes it is
How do i show pictures?

[redsea]

If i use light weights rpm is 13500 
If i use heavy  about 12800
And about 20 gram 11500-12500 rpm and max out about 13500 rpm
But still always the same marks on the variator  use a black ink to mark 
Misding about 8 mm

on your first picture did you mark variator all the way to center to see if you get all the way to the bottom


your back pulley looks to also have 8mm left
can you post a picture like this



this is a fulley maxed rear pulley

[Zino]

for shiming to get full belt travel on the bottom for best take off
i only need one shim or no shims in this pictire i have to many shims you want the edge of the belt to just get to the edge of the drive boss .


lucass2t and aeroxbud might have a little more knowledge on the stage 6 stuff

I locked the front pulley and took away the tork spring and it looks like the belt is perfect size
But i cant get it to go all way with light weight and heavy weights
Or is the power to low to make it go all way 
But it feels like going really strong
In 11700-12500 rpm range

That's defy the right belt for the long case.
I had this setup on my old aerox with a similar race cylinder. I seem to remember I never got it to the very edge, but it was close.
What final drive ratio are you running?
