yamaha cygnus 125 variator metal knocking

[megalodon]

hi all fellas,

my other scooter is 2008 yamaha cygnus ,it has 20.500 miles/33.000 km , front variator area having a noise , it's kind of metal knocking,it does this noise only at idle.. i replaced new belt and rollers original yamaha ones aprox 200 miles ago..standart factory settings on it.belt i bought with chasis
number, i'm sure it's not wrong belt..nothing modified at my scooter. also during first movement accelerate clutch is shaking at hard style ..it's like grabing the belt at the clutch and release it and again grab..if i accelerate hard , it does less, if i accelerate slowly it does much but on cruising nothing problem on accelerate whatever i do..always it does it job well.. i don't know what can be cause of this, because my clutch is clean and i never ride it hard..i prefer always smooth riding. video at bottom..

Tem de trocar os deslizadores do variador
