eastanglianbiker Posted March 12, 2013 Share Posted March 12, 2013 can you see any sign of oil leaking out of the forks where the seals might of blown that would make it sit lower/sink when st on Quote Link to comment Share on other sites More sharing options...
jal123ddd Posted March 12, 2013 Author Share Posted March 12, 2013 hi there thanks for a reply on i can not see any oil leak or could you say i may need to bleed the old oil and put new in but thinking of after puting the question up i was haveing trouble with the front break and i have adjusted the arm on the drum by riseing it a fuw notches up which the break works a lot better and have only seen it since then Quote Link to comment Share on other sites More sharing options...
eastanglianbiker Posted March 12, 2013 Share Posted March 12, 2013 mgiht be the brake is working better then as that will pull the forks down/make the front end dive more if brake is gripping harder have you ever checked fork oil levels or changed it that might help and use slightly heavier oil in them Quote Link to comment Share on other sites More sharing options...
