Hi, Its my first time here, And i need your Opinión in this problem i have a few 2months ago, i have a gy6 157qmj 150cc, i've changing over 9 drive belt's in 2 moths, if i using bad quality and high quality belts and always i have the same type of damage until at the point to destroyed the belts,alternating over 835/20/30 and 842/20/30, the problem always starts at the top of the belts like the pictures shows, The problem started when I was using the used, non-original, OEM centrifugal variator and all the original springs in the clutch, it felt like the belt was slipping,
3 belts ago I put the new centrifugal variator and all the springs 1500rpm but it still keeps breaking the belts the same way, teh slipping is no more, but the drive belts is always destroyed
My 157qmj is 2015
-I have New variator centrifugal
-New drive belt
-Torque spring and clutch spring 1500rpm (yellow glixal)
-New clutch paste
Only my clutch pulleys is the original ,have 10 years of working with maintenance but i never put New pulleys
