Super Stock Bz Noise

[Danbox]

I have a Super Stock BZ motor that makes a sort of screaming/squealing sound. It's not terrible, but it doesn't sound like it used to, and it's not as fast. I imagine if I oil the bearing/bushing and the sound continues, I should replace the bearing.

Does that sound right?

Sounds like the bearings need oiling.

I kind of brought this thread back from the dead, I know, but I tried oiling the bearings and it didn't seem to make any difference. I suppose I might need to true the comm and/or replace the bearings, but I'm just not going to do that. If anybody covers shipping, they can have it.
