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

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 !

I see , i thought they were air-assisted forks.

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

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 .

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.
