Sorry for not replying sooneer, not online very often these days. The weather has been so nice, that I have spent most of the time riding.
Ask any scooter dealer what kkind of dry lube they use; McLube is one, and there are more. As long as it's dry, it'll work.
I don't know if spraying dry lube will help stock rollers, I do know the Dr. P. Sliders work better, smoother.
