Don't worry about it, nothing unusual. The slippers are rarely made flat and the drum face is never perfectly square, it'll wear itself in.
Only reason I striped it all was to check if anything a miss as when I slow down for a car to turn off the cvt doesn’t seem to drop down to get high revs again. I have to stop then It will. It’s like the cvt gets stuck in to low gear
Thanks got 3 new sets today so I’ll have play it had 9g ones and looks to have a red spring at the moment will try lighter weights first
