I just got an M8 with Fox Floats and the front shocks seem really soft even though I have pumped them up, but when the pump is connected to the shock it always gives me a different reading. I have tried two different pumps and they both do the same thing. My brother has an F6 with Floats and they are way stiffer compared to mine.
So what I am asking is if the shocks are supposed to be softer on a mountain sled or not.
Make sure the skis are off the ground when checking the pressure. It tells you that in the manual. Do youself a favor and empty all of the air and fill it with nitrogen (not required but highly recommended). My local dealer only charged me $10 to fill them. He had it done in less then a minute.
It was just a silly mistake! I was only threading the pump on by hand which was not getting it tight enough, so I used pliers. Pressure was only building up in the pump and hose and not going into the shock.
