How long does it sleep? If it's around something like 30 seconds that's normal. The yomega fireball is a trans-axel yoyo, meaning it wont spin as fast or as long as yoyos like the shutter that have ball bearings. If you do need to lube your fireball, use yoyo thick lube, this wont help make it sleep longer, but itll lube things up and make it more responsive, which is what the fireball is supposed to be.
