Pistons

• The pistons have valve recesses for the intake and exhaust valves.

• The piston skirt is coated to reduce friction between the piston and the cylinder.

• The connecting rods are fracture-split on the big end to ensure a perfect fit between

connecting rod and connecting rod bearing cap. For this reason, the pairs of connecting

rods and connecting rod bearing caps must be kept together during removal.
