    888 sl ata problem

    so i got my 2007 888 sl ata and have been riding it for a while and its nice but if i pull up to manuel or wheelie the fork bottoms out really hard like its like the fork dosent rebound its just kind of falls back down.. it comes down so hard you can feel it thunk down at the bottom.


    i know theres a few of you on here that really know your stuff so im hoping one of you can help me out.

    i guess it would be topping out

    raptordude im not sure i just picked it up... for topping out which air chamber would i check there is two right?


    i didint get a manuel with the forks and my comp gets funky when i try to pull the manuel up on zokes web site.

    so im having a hard time learning about/figuring out these forks.

    As for air pressure you should be running at least 30 PSI in the PAR chamber over the SFA Chamber.

    Do 95 in the SFA and 130 in the PAR and see where you go from there.

    a)turn rebound to + side
    b)if this doesn't work, check your oil levels
    This shouldn't have anything to do with air pressure if I understand correctly that you are harshly TOPPING out not BOTTOMING out. Bottoming harshly would require proper air settings, likely more oil, and proper compression settings.

    Marz only recomends that you not let the PAR pressure drop below the SFA. They state in their ATA set up guide to start PAR 30 psi above the SFA and decrease the PAR closer to the SFA or equal to it without going below it to have a less pogressive ride.

    I think I know what you're talking about.

    If the bike if just sitting still under its own weight and you lift the front wheel off the ground, do the lowers seem to drop a fraction of an inch and then make a slight "klunk"?
    .
    If this is what you're talking about, it is normal. Sort of. Not all do it, but mine did and also my 888 WC does it and many other Marzocchi's that I have had in the past have done it, but not all. If this describes the problem you're having and nothing is actually loose, then it's nothing to worry about.

    ^^^^ Do you own a shock pump?????? Check your pressures. Thats what everybody is illuding too when their talking about PAR and SFA pressure. You haven't said what you have the fork set at. If everything is set properly then you have a problem. My 888 SL only makes a nice hissing noise as it rebounds, and is super smooth.

    ^^^^^ Bingo!!!!!!!!!! Don't ride that fork untill it has the air setup right. We're not talking about a coil fork with air assist here. We're talking a about an air sprung fork. The RC2 side has no spring what so ever. Hopefully your air cartridge wasn't damaged.

    Good luck. Read that ATA set up guide I posted and remember subtract about 40 or 50 PSI off of their (marz's) recomended air pressures.

    The air pressure in your fork has nothing to do with it topping out.
    Most likely ther isnt enough oil in the damper leg. Check your oil levels and maybe apply som more rebound damping.

    Air springs have a positive and negative air chamber. If there is not enough pressure in the negative air chamber, it does top out. So... Yes, air pressure would affect whether or not it tops out.

    Oil levels are probably off too... that's common for Marzocchi.
