Engine gear → bearing core

It was serandipity (don't know how to spell it) that my engine gear broke cause my to tinker around the inside and accidently let the winder spring (at the top on the inside of the engine gear) to pop out thus the bearing gear (as I call it) was born I dont know how good though. Does anyone know if its worse then before? and has this happend to you.
I don't get exactly what your are saying here. What is a "bearing gear"?
just a name for it and I'm curious if if anyone else has done this as well as the performance since there noone thats even half decent at beyblade near my house so,
So it's an EG working with like a spin free shaft? Whatever it is now, it's considered illegal to use.
I'm locking this topic since I don't get the point and it doesn't belong in this forum.

If you have any further questions, post it in this topic:
