great write up from Scudman.
there are about 5 threads related to fork oil
I am playing with my suspension and such and so learning about suspension fluid.
for my particular case:
Pregen ninja 250 with newgen ninja 250 suspension modded.
.75 kg/mm springs
recommended weight is 15wt from racetech ( I 'll call em again and see if they tell me their oil's viscosity and properties)
though our forks do not get got, I read it is recommended to get fluid with a index (which indicates its resistance to change it properties at higher working temperatures) of greater than 150.
also probably ordering a fork rebuild kit, not sure yet..
Wondering how you bike gurus can share some light on for oil info..
Race tech says they use Spectro Oil and Bel-ray oil is the closest in properties to it.
