so I got my duncan hayabusa now and it fell on the ground so many time, (marble surface) and got wobble on it, but I wonder how I can make my hayabusa sleep long because it only sleep for a short time. does the wobble affect the sleep time? or should I clean the bearing? or should I remove the mod spacers?

Cleaning the bearing to help with sleep time. Duncan will be making weight rings for yoyos with FHZ caps (such as the Hayabusa) which should also help with sleep time.
Mod spacers can cause vibe in a yoyo so follow this guide to tune the vibe out

Improving your offstring throwing with time will also slowly help spin times become longer.
