andy m Posted October 13, 2011 Report Share Posted October 13, 2011 Put some new fork seals in the Fantic 200 t/s. Have they got as std some tube/ spacer above the spring?? I have some 4" pieces in mine, fitted the seals, 2 in ea leg ??(this may not help??) and 200cc of 10 grade oil. They seem a little stiff now, may be okay after a trial but may have had spacers due to springs being worn ?? What have others found in their forks when stripped ?? Thanks..

treevor Posted October 14, 2011 Report Share Posted October 14, 2011 Mine had a 2" preload on them but I remove it and put power steering fluid in. That made them much softer and more responsive, I added 1/2" spacers to get the 'sag' set up right Quote Link to comment Share on other sites More sharing options...
b40rt Posted October 14, 2011 Report Share Posted October 14, 2011 (edited) Think they are the same Marzocchi forks as the SWM, if so :- 2 seals per leg approx 50mm spacer above springs. I use 220ml tqf per leg. (But Woody recommends 200 & he's usually right) If when putting the fork caps on you dont have to compress the spring by approx 30mm the springs may be past their best, I got a pair of 35mm springs from Bultaco for approx £27 delivered.

andy m Posted October 23, 2011 Author Report Share Posted October 23, 2011 First trial today since doing forks, as I said new seals 200cc oil but when going over step or pick up front end quickly they clunk on the rebound?? springs shot ?? Any ideas?? Quote Link to comment Share on other sites More sharing options...
b40rt Posted October 23, 2011 Report Share Posted October 23, 2011 As before Quote Link to comment Share on other sites More sharing options...
andy m Posted October 23, 2011 Author Report Share Posted October 23, 2011 As before I did have to compress them by over 30mm but with the bigger spacers they must be shot. Is there a free length measurement for them ?? or best to get some anyway. Checked the Bultaco site they don't list them . Quote Link to comment Share on other sites More sharing options...

Checked the Bultaco site they don't list them . 30mm sounds ok if standard spacers, 220ml should stop them topping out. http://www.ebay.co.uk/itm/Fork-Springs-Trials-Motocross-Bultaco-Montesa-Pre-65-/220870238985?pt=UK_Motorcycle_Parts&hash=item336ce46309#ht_500wt_969 Edited October 23, 2011 by B40RT Quote Link to comment Share on other sites More sharing options...
