With bearings if y our doing a Stock rebuild Stay OEM. I honestly prefe OEM honda bearings all day long but in my last couple of builts Ive been using Clevite Larger varity and I feel they stand upa lil better. I think its great your learning how todo all this BUt you may need to take a trip to a machine shop and hve the guys mic your shizzy and elp you figure out exactly what you need. I hate when you get a nice as engin build and 100mileslater your bearings fail...
