I have a Mega Spinfactor. Its rather old but has been kept in a case on and off for a long while. The yoyo has been making a bearing noise, and not returning. It also has a wobble in it, when thrown straight. When you look at the yoyo closely its not perfectly balanced?
I took it apart and cleaned it on the inside, and put a new standard yoyojam bearing in it. I also replaced the Tom Kuhn brake pad on it. It definitely seems to be working somewhat better. It still has a bearing noise in it, and wobbles as though its out of balance.
I lost my yoyojam lube so I am using the bearing right out of the package with no additional lube.
If I have damaged my yoyo somehow and it is not repairable. I would like to try and brainstorm on what caused it so I can avoid it in the future.
