[QUOTE="NO HAND, post: 810859, member: 18937"] Motometal hows'it goin', Per the procedure the bleeding phase is done on the bench and the excess oil has to be removed from the inner spring area before installing the damper unit inside the fork tubes. The oil from both chambers are supposed to be completely separated - to my knowledge. The ideal viscosity for each chamber is sometimes different. In the case of our CR, the outer chamber is in charge of the air spring and the hydraulic bottom out cone. An air spring is not really affected by the oil viscosity so it gives us the opportunity to tune the hydraulic bottom out cone (oil lock ring) with oil viscosity. Thicker oil in our case seem to work better for everyone for the outer chamber, because the tolerances for the oil lock ring are way too slack. The inner chamber has the base and mid valve and this area is impacted by oil viscosity. Thick oil would make the rebound too slow, and perhaps be prone to aerate easier. This is why a lighter oil is most often suggested, such as the Motorex 2.5 [/QUOTE]
