Nothing is probably wrong with either - you probably have a set of semi-finished conrods. Atomic supply them (part #306200 and #306201-SF) undersize so professional engine builders can hone the big and little ends to provide the exact clearances they require. Please contact Atomic and we will recommend an Engine builder/machine shop in your area that can finish-hone the rods to size, or we can do it for you free of charge.
