A well-produced crankshaft should also be correctly balanced to reduce vibration in the motor and the oscillating masses should be kept low to facilitate an improved performance from the motor. The big end bearing rotates at the same rate as the motors rpm, receives lubrication from the two-stroke oil contained within the fuel mixture and has to convert the pistons abrupt change of direction twice during every single revolution of the motor.

The crank pin, that connects both the crank webs with the con rod, requires pressing together during assembly to a precise stiffness, to avoid the crank webs to become misaligned during operation. To enable the fuel mixture to adequately lubricate the big end bearing the lower eye of the con rod should be provided with lubrication slots.
