What's the stock oil volume? Anyone know?

The whole point of the ICS is to keep the oil in the inner chamber pressurised to prevent cavitiation (bubbles forming that reduce damping efficiency). The KYBs don't run a preloaded ICS so they generally allow a little cavitation at the initial stroke anyway, but the further into the stroke you go the further the pressure increases.. however the increase is linear!

The oil volume acts as lubrication for the bushings and seals. The remaining volume of the fork (filled with air) then acts as a spring.. however the curve is not linear.

Usually oil volume has much less effect on initial stroke, and more to do with ramping up and bottoming resistance.

BUT! The whole system works together.. valving, springs, air gaps, etc.
