Gear mesh has to be straight and not tilted, meshing should be done with like 2 fold newspaper anything below the 40 gram mark paper is good.
You should have some end play in your clutch bell, the screw that keeps things down should be tightened down with some play, I keep about 0.25 to 0.5 of end play depending on the weather, what happens in the bearings that you are eating is simple, your clutch bell is heating up from the clutch shoes engaging, that heat travels to your bearings and bearings expand no end play and your going to pop them wide open, with a little end play they expand and contract with the heat, clutch bells u should invest in decent bearings, If your race look at ceramics.
Keep it clean and you will have a long lasting solution....
However does not mean to say they will not chew up with time, the most I ever get out of them is threw half a season, racing condition they get changed out per seasonal race.
