I onley use the clutch for take off then once it hits full lock I intend to keep it locked bliping and reving is what kills them lots of begeners like to give the bike a few quick blips before take off or they stop and let the clutch unlock or both and melt the epoxy that holds the pad to the arm
And the next problem of china clutch is setting the spring. Just change the spring to original blata and it works. Mostly need also a smaller clutchbell, because they dosn't fit on 80mm bell, nearby 78mm bell it works.
