I got my Worlds 2010 B-Grade 888 today and I LOVE the hubstacks! I was wondering if I could get a longer hubstack sleep time by cleaning the bearings. Would that actually increase the time? Would it screw it up? Thanks!
Just do hubstack sleeper many times
that is the way i do it 
clean it like a regular bearing and ive found out that on my friends pgm cleaned duncan berings are better than normal hubstack bearings
