ormplus Posted November 1, 2011 Report Share Posted November 1, 2011 since when on modern bikes do we let the air out the forks. for t/less you get puncture strips called dog turds and the tool to apply them.you will get them at any good trials dealer.

hrc1 Posted November 1, 2011 Report Share Posted November 1, 2011 GG Marzocchi forks pump up. Let air out after riding. But be gentle with the small screw. Quote Link to comment Share on other sites More sharing options...

jandyb Posted November 1, 2011 Report Share Posted November 1, 2011 You don't have to let the air out of your forks, only if you want maximum performance from them. Jon Hmm.. had Marzoccis for several years. Never ever bled them... But I guess the screw is there for a reason.. OK.. I want maximum performance, how do I bleed? Just open the screw, or is there some pumping involved? -Jan Quote Link to comment Share on other sites More sharing options...

Jon Maybe I should explain a little further. When you set the suspension damping, you want the forks to perform as consistantly and predictably as possible. Pressure buildup in the forks during operation (pressure normally the case) will alter the compression/rebound response. Fork seals, due to their design, tend to act as a one-way valve, and to a certain degree, allow air to enter the lower tube and not allow it to exit. As a consequence, your fork action will probably be a little different ("harsher", some may describe) from the cool morning to the warmer afternoon for example. There are other variables, such as fluid temperature and material thermal expansion that change fork action, but adding fork bleeders will allow you to eliminate a variable, which is usually a good idea. I run bleeders on all my forks and check them now and then, it only takes a second. Shock seals are another animal and require high pressure to seal well, per their design.

stevel Posted November 2, 2011 Report Share Posted November 2, 2011 To get back to bondy's original question, I believe the screws he is referring to are nothing to do with bleeding the forks (when did anyone last bleed their forks?) but are the suspension adjustment screws. The right side (as sat on the bike)adjusts the spring pre-load and the left side adjusts the damping. Quote Link to comment Share on other sites More sharing options...
