    04 Z1 FR Oil Levels

    Can anyone tell me the correct oil levels for the Z1 FR? (Looking for mm from top with fork compressed and w/out springs) I am 185lbs and do urban drops and FR on the bike.

    I set it up by trial and error the first time, and am due for another change soon.
    Thanks.

    Marzocchi no longer gives oil....

    "level" specifications for their 04 and newer forks. Oil is measured by volume in CC's. The reason for this is the advent of the ECC and ETA cartridges and some of the new dampers that are being used. They require VERY specific oil volumes to function properly. Measuring the oil out in cc's and the pouring it into the fork is more accurate for this purpose.

    The correct oil volume for your fork is 155cc in each leg. If you insist on using oil height, then messure out the oil in cc's, pour it into the fork and then meassure it using the old dip stick method. Write it down and there you go. You can even fudge with the level a bit in the NON-ETA side for tunning purposes if you like. Just don't mess with the ETA side, it's too easy to run the oil level to low and hose your ETA operation. Also be aware of your damper type and pay attention to the damper operation. If you loose damping you are most likely running to little oil.

    I checked their specs online and it turned out to be pretty much bunk. With the specified cc's, the fork wouldnt compress more than two inches into its travel, and rebounded like molasses. Had to reseat a seal after testing it out. Spent quite a while tuning it in and now it works good, but would like to see what the measurements are for ruture refrence. (I didnt bother measuring myself because I wasnt going to tear it down AGAIN)

    If I could afford it, I would get a cartridge and just toss the ETA. I never use it anyways, and have had problems with it in the past.

    Thanks.
