+ | From '91 to '03 the Crankshaft/Flywheel was balanced according to the engine size, either for 883 pistons or 1200 pistons. From 2004-later, the flywheels are balanced to be between the weight of the 883 & 1200 pistons. ((http://hammerperf.com/883conversions.shtml)) This is one reason why riders would use Wiseco pistons in early (pre-2004) 883 to 1200 conversions - the Wiseco 1200 piston & pin was closer to the weight of the 883 combination rather than the 1200 piston & pin from HD. | ||
