should I clean my steel kk? It came with my phenomizm, so I would still have my ceramic kk not cleaned in case it somehow went wrong. Just wondering what the benefits of cleaning were.
When you clean a bearing, it takes out all the lube:
PROS:
Spins longer
CONS:
Screaming Loud
Wear out easily
Lubed bearing:
PROS:
Keeps the bearing more safe from wearing out
Can sometimes help to be unresponsive
CONS:
At FIRST, it is responsive
At FIRST, it doesn’t spin as long

Yes - lube lightly.
