I have a buddy changing the oil in my shock on my 07 450F. (He has done it before) It has been revalved by Factory Connectioon but to my knowledge that should not change how much nitrogen goes in correct? It will be up to me to get the nitrogen put in at my local shop that has the nitrogen but doesnt know how much to put in. How much should be put in and will it matter if it has been revalved by Factory Connection? Thank you.
