    i dropped off my forks to Krooz Tune this arvo. both seals are rooted and they need a good servicing. the right leg has ZERO oil left in it. :dry:

    i only let them get so bad due to lack of funds. and im getting them fixed as the left is leaking onto my disc and giving me some puckering moments upon braking :laugh:

    while i was there, i asked them if the could put some bleeders in. they said NO. they reckon they are shit and let moisture into the forks as they suck air in upon rebound.

    the only good ones are the factory KTM ones i was told and these are bloody pricey :(

    do you lot run them and if so what has been your experiences…

    and remember…this IS in the tech thread :P

    I have a set mate. Put them on the Sherco for while and found they sucked more air then they released. Thought it might have been the thread not sealing properly so put them on the Husky and they did the same thing. Now they are just a bit of bling sitting on the bench. I just get the screw driver out mid ride now.

    the 400 has them and i quite regularly press them to release the built up air,, there is a diffence in the volume of air depending on the terrain,,cant complain about them. B)

    My set cost $85 and are guaranteed to not suck air, I had three different brands before I got a set that didnt. I was happy using a screw driver like Mal just that I got my set for free. Boony you should only bleed your forks when the are fully extended. Even if your bleeders are sucking air Boony conventional forks will put up with it where USD’s wont.

    I would say Menace unless you buy real good ones just bleed them with a screw driver

    (cant believe you wrote that about the tech thread it would be only you or your twin Boony that would derail it :P )

    I have fitted them and seem to have much more air when I press them now than when I just undid the screw. After reading your question I am wondering if the air is getting sucked in like you were told!

    sorry forgot to mention the bit about releasing the air whilst the forks are fully extended, i just pull the bike up on the stand and then press the buttons.

    What problems could be caused by the bleeders sucking air?

    #179071

    Hey Nickj

    I think it may be that the added pressure puts more stress on the seals. This would explain why USD forks suffer more. If this is the case I will take them off my bike.

    Do you think the air that’s being sucked in and pressurizing the fork would effect front end handling?

    In a heart beat ;)

    If the fork is sucking in more than it builds up without bleeders fitted then it could affect the fork. Someone here will know more then me though.

    Anyone?

    That could explain why after fitting the bleeders last weekend I rode for 2 hours to a rocky hill climb and struggled with the front end the whole way up ?

    Or maybe I was just riding sh#t that day!

    Either I think I have lost faith in them now, back to the screws for Saturdays ride !

    I’ve got them on the WR to try and stop the problem of leaking fork seals by letting some pressure out. Cant say if they let in air, but the problem of leaking fork seals has reduced. (not stopped, crappy USD forks)

    Do you guys with conventional forks blow seals very often?
