dave dix Posted October 20, 2006 Report Share Posted October 20, 2006 Hi, does anyone know the min-max air pressure to pump up my 59n mono 1987 250? It has the air valves fitted to the top of the forks, thanks Dave Quote Link to comment Share on other sites More sharing options...
paioli Posted October 20, 2006 Report Share Posted October 20, 2006 air valves there to let excess air out as they often tend to blow themselves up try fully extending the forks and pressing the valves befor every trial ! Quote Link to comment Share on other sites More sharing options...
dave dix Posted October 21, 2006 Author Report Share Posted October 21, 2006 I see , i thought they were air-assisted forks. Dave Quote Link to comment Share on other sites More sharing options...
pat Posted October 31, 2006 Report Share Posted October 31, 2006 (edited) Hello, Im searching for spring data for TY250R. 1. Spring constant Nm/mm? Have rebuilt the forks, Im almost satisfied with the performance, but just little bit harder would be perfect. Guess new stock springs solves the problem. What W-oil are you using, manual says something about engine oil W10/30??????????? I have tested hudraulic W5 to W15, in worse case I have to look at the cartridge for more rebound. Please help, Pat Edited October 31, 2006 by Pat Quote Link to comment Share on other sites More sharing options...
paioli Posted October 31, 2006 Report Share Posted October 31, 2006 repsol 10/30 in gearbox , forks try inch longer spacers you can make these out of an old pair of renthals, 7 1/2 weight oil , try 280cc in each leg then if need be, top up by 10cc until your happy, try the spacers first .

pat Posted November 1, 2006 Report Share Posted November 1, 2006 (edited) Paioli, Thanks! I cut 20-30mm, each side of the Renthal bar when I bought the bike. 7.5 oil sounds perfect in my ears. Pat Edited November 1, 2006 by Pat Quote Link to comment Share on other sites More sharing options...
