hey Freakshow, I’ve also wondered about this as I saw some ohlins and it looked like someone just took the reservoir off and put a valve in there. My answer would be no though (not a good idea). The reservoirs have either a piston or a bladder (im not sure on Works shocks) separating the gas from the oil. If you were to take the hose off and stick a valve in there I don’t think it would work properly as the gas will mix with the oil and aerate it. The emulsion shocks that are like this eg Fox gas shocks have different valving calibrated to work on this emulsion princible with nitrogenated oil.
