As per title I have just got a spesh FSR with a set of marzocchi bomber comp mx front forks. I have a shock pump and want to check they are set up correctly for my self.

I weigh about 77 kg. And use the bike for general trail riding and bit of Xc.

Please could people let me know what sort of pressure I should be running and
Do each leg of the forks have different pressures ??

I have down loaded an owners manual but got a little confused

Any help much appreciated

    both legs run the same pressure. add what you need to give the sag you want.

    use the manuals numbers as a guide and adjust to suit.

    My MX Comps only had one schraeder valve on them (one the RH leg).

    I have checked and mine have 2 one on each leg.

    When I checked the pressures the left leg (if sitting on bike) had about 25 psi in it
    And the left leg was very low like about 5-10 psi

    Does this sound right or is there a fault

    What Nick said. Set the sag at 25% roughly. Whatever equal pressure in both legs gives you this.
