is it possible that 130mm in the fork will be only 620-640 cc ? i changed the fork oil today by only opening the upper side and drained the oil and left the fork up side down for half an hour and then filled it about 100mm pressed it for about 20 times (20cm up n down) and waited for 15 min. till all the air bubbles went out,than sprayed the extra oil out with a sprayer till i got 130mm. is it ok? or 310-320cc for each leg sounds odd?
