    Losing Air During Ride

    Hello, I have 2 questions

    1) I did a search in the forums for this specific issue but I didnt see anything that was close. A few weeks ago I purchased a new Trex EX8, which has the Fox RP2 rear shock. Yesterday I took it out for its first "real" ride. I set the rear shock to 140psi at the begining of the ride (note the temperature outside was 100 deg F). At the end of the ride the rear felt a bit soft, I didn't think to check the pressure then, just thought it was me not used to the bike. Late that night when I was home I checked the pressure and it was at 120 psi or so (note the temperature was now around 75 F and high humidity).

    I wouldnt think the shock would lose that much air during a ride (or that much just due to the temp change). Is this normal to lose air during the ride? Or does the shock need to just get 'broken in' since this was its second ride - and a tough one with lots of roots, so the rear was working very hard.

    The fox Float RL fork lost some air but just a pound or two - probably from the shock pump filling.

    2) the second question is that after this ride when i was checking/pumping pressures i noticed I got a bit of shock oil blow back when releasing the shock pump - both from the fork and rear shock. Is this normal? It hasn't done that previoulsy. I did notice that the fork was a bit more 'oily' than after the other ride - same with the rear shock canister. But that looked normal, it wasnt dripping just wet.


    Thanks for any insight.

    I'm disappointed, I thought this thread was about farting.

    lol

    sweet choice in bike! 08? i have an 07

    just putting a pump on and off ill lose you air so going from 140 to 120 wouldnt surprise me to be caused by the pump. just ride it and dont check the pressure for a couple of rides or so and if you notice a BIG difference in pressure...then just try to get the shock warrantied.

    also its normal to get oil to come out from the valve. how much oil? thats a judgment call
