how the factory says it should be done and and the technique

DFX BETA XTRAINER SHOCK PISTON Renthal Ventilation:The DFX XFactor upgrade kit for your Beta X Trainer replaces the stock shock piston to get a MASSIVE improvement in handling, comfort, traction and cornering. Inertial mass is lowered by the significantly reduced weight of the piston over standard, temperature (friction) is lower, and smoothness is dramatically increased. The high flow compression ports soak high speed bumps without deflection, give more linear damping, and less chance of cavitation.
