What direction should bearing flanges be? I always faced the flange inwards thinking this would allow consistent flex on both sides and give the sprocket carrier more room if needed. Our Compkar dealer said karts come from the manufacturer with both outboard bearing flanges facing left (so inboard on right and outboard on left).
Any difference is negligible. CompKart runs the left side out from the factory, but BirelArt runs the left side in.
