I stated this earlier, but I will repeat it once more, since it is significant. The stock shock absorber doesn't hold much air. If you hold the schrader valve down for less than a second, all the air will be released. Obviously, the air volume inside the shock body is very limited. Therefore, if you wish to add air to the shock, I suggest you use a hand pump, or set the pressure regulator on your mechanical pump to 45 psi. Otherwise, you risk blowing an oil seal in the shock.
