It seems to be working good I have about 6 hours on it now & still sealed up great. I was a little worried it might let oil past then build up enough to push the factory seal out, so far so good though. This list I stole from Motorrad so credit goes to him. I just added an s to the part # to get a sealed bearing then popped the seal from one side. The one you want would be 6305s.
Thanks again Dave for posting up this info on your build it saved me some $ in my build.
An additional note on bearings though , get a quality bearing , the factory Japan stuff is all good, excepting plastic cages, so if you do interchange make sure your not sacrificing quality. FAG
brand bearings are German made , my preference , Theres a brand out of Austria that evades me at the moment thats good too. China & Taiwan junk.
