ok as a rule these do ok with a pipe and a set of 5 gram rollers but if the torque driver spring on the clutch is too strong(been upgraded) then the rollers fight against it and lose !so the rollers need to be heavier.basically the rollers havent got enough weight to push the belt out to the edge of the variator as the pulley on the clutch is keeping them from moving and gearing the bikes transmisson up.i would try putting your standard rollers back in but only use 4 of them and arrange them so they are still in a sort of square in the variator.try it and see how it goes if its ok then leave it like it it wont hurt it at all.
