Guys, on the "sealed" bearings, I have a question. On the dirt bikes, I typically would get these new sealed bearings and open them up. It was easy t do with an exacto knife. Most often you woudl find almost no lube inside them. I'd then wash them out and dry the bearing. Add in some decent waterproof grease, then snap the seal back.
The bearings lasted a lot longer after doing this. I wonder if it woudl be a benefit to do with the streetbikes, too?
