This is only temporary till the seat tempers over time. You open it wide open that should quit. » This message has been edited by DUNBAR on 27 August 2003 27 Aug 2003 at 11:46 pm #295027 racefanoneParticipant Sounds like you might have a loose washer washer or a washer that has came off of the stem Author Posts Viewing 2 reply threads You must be logged in to reply to this topic.
