    do you bleed the air out before or after you adjust the clicker ?

    • @GRmotors
      @GRmotors  2 роки тому +1

      It doesn’t matter, you’re adjusting how open a valve is inside of the fork to allow oil flow. The air builds up on top so it doesn’t affect it in any way.

    If your settings are screwed up, how do you return to standard factory setup? I can hardly feel or hear the clicks so I have no idea where my factory setup should be to begin fine tuning. Cheers

    • @GRmotors
      @GRmotors  6 років тому

      Sometimes you can find the factory settings in the bikes owner manual or online. If you can't find them I've heard the best thing to do is turn the screw all the way in or out and then go all the way the opposite way. Like if you turned it all the way in then go all the way back out and count how many clicks you hear. Once you know the number, say it clicks ten times, then start in the middle which would be 5 and work from there. Just don't over torque the screw, once you feel resistance don't force it or you could tear it up.

    • @oo0Spyder0oo
      @oo0Spyder0oo 6 років тому +1

      Thanks a bunch, I can feel it go a little loose where it would probably be a click, sometimes it's a click and others you can't hear at all so I'm feeling my way around.
      My manual states 10 clicks out is the standard setting, it was just knowing when I had any clicks, I think I may have it ok now, feels like every third of a turn sets of a click, does this sound right?

    • @GRmotors
      @GRmotors  6 років тому +1

      Yeah that's right! Sometimes you won't hear the click but you'll feel it and yeah a 3rd of a turn is about right

      It’s probably close to where it needs to be if the suspension is stock and settings haven’t been changed. But if it’s used the first step would be to get the suspension rebuilt to make sure it’s performing correctly and then adjust from there. Woods riding typically likes soft settings and slower rebound because of how rough it is

      Just bought a used dirt bike. I've never had one before.
      But the top of my fork has two screws. One in the middle, and one off to the side. No letters or anything next to that one.
      Just looked at it again. I think it has to do with assembly. One was loose so it made me think it was an adjustment screw.

    • @GRmotors
      @GRmotors  Місяць тому

      @rossokeefe9268 May be sprung or valved too stiff for your weight. But for the clickers I would run the compression and rebound all the way in and then all the way out and see how many clicks there is. And then go half way back in. Do that on front and back and ride it like that and see what it feels like. That will get you close to stock settings.

    • @GRmotors
      @GRmotors  4 роки тому

      Yeah it’s the separate function fork. So only one fork has a spring in it and the other controls your dampening. So the one with the controls you see on top is your Compression (stiffness) adjustments, and the same fork has the rebound (how fast or slow the fork returns to extended position after you hit a bump or jump) adjustment on the bottom of it. The other fork has a blue hex nut on top, it turns. It adjusts the preload (how high or low the front of the bike sits)

    • @jettgriffith7216
      @jettgriffith7216 4 роки тому

      GR.motors so if I adjust just one side it’ll do the same for the other side? I don’t want to have my two forks on separate settings

      Ok, it probably goes by “turns” instead of “clicks”. So I would turn it two full turns and see what difference it makes and then if you can’t feel a difference go a few more turns until you are feel difference and then you can decide which way you want to go with it. Typically turning right will make it stiffer and left will make it softer
