Been awhile since using one of those cvt systems- I don't recall any real tuning tips for them other than the spring adjustment (lower engine speed for contact with the tighter spring setting) making sure the springs are solid/tight(not stretched out),clean pulleys (already done), the buttons being fresh as you've already done too. Make sure the weights aren't wore out where they make contact with the pulley(excessive cupping). Of course making sure the belt is turned correctly as Tom stated. Any blueing on the pulley indicates excessive slippage, from too steep of a slope or too much weight in the buggy. Once there's blueing/glazing it hardens the pulley and the belt will slip very easy from that point on-replacement is the only long term cure.Make sure the spacer on the shaft between the pulleys is smooth and lightly lubricated on the motor shaft only. Since you've already tore it down you have a good idea of what to look for. Good luck
