I'm running a #5 also and it works well.
I just changed my rear bearing and bought a TKO from a guy on here which is pretty loose for a new bearing.
It has twice the play of a Novarossi bearing so i just bought a novarossi one onstead.
How do the Boca Steel ones go?
Anyone else tried any other good bearings with luck?
remember what i told you about the tko bearings for the plus crank engines 14.5x26mm they are looser than the worn out ones you pull out of the engine !!!!
