These bearings have relatively little load put on them, and dry bearings last ages anyway. Bearings are only $10 a set so i see it as a cheap performance mod.
My process is:
-Put them in a container of petrol, and shake em for a few minutes, leve them for 30 minutes, give them another shake. Then dry them on paper towell.
-I repeat this about 3-5 times using FRESH petrol each time.
-I then thoroughly dry them by shaking them in paper towell, and leave them for an hour for th remaining petrol to evaporate.
-Finally, i spin them for 5 minutes on mini Z motor shafts, i refuse to use a dremel, because the vibrations from a dremel can destroy my tiny 0.5mm balls
:clown:. And i have done it before, the mini Z motors run very true with negligible vibration, and are much nicer to your bearings.
Then i chuck em in, and make sure they roll nicely (i.e. the rear axle rolls for almost 1 minute with a flick from your finger)
This mod can see a 10-15% gain in top speed, also, setting the gear mesh with paper shims can see a performance increase…..
