For 2004-'16 models we recommend that new 3-1/2 inch bore cylinders be purchased. No combustion chamber modifications are required due to the dished piston dome. Stock 883 heads produce a reasonable 9.6:1 compression ratio. No engine removal, crankcase splitting, or rebalancing is required. Coated piston skirts for reduced friction during break-in.
