DMII response prob

I got my DMII yesterday, everything is great, and now, even with the speed bering in, there is to much response!!! funnily enough, it worked great till about an hour ago. yes i changed the string, still no joy. What do I do!!?!?!!? Do I need some thin lube or something?

i would clean the bearing before putting lube in it. lube will make it responsive. ive played mine with just one pad in it and it played awesome.
