does any one know how much fork fluid to put in A 98 husaberg FE 600 with WP suspention, I put in my new seal and cant find my book that tells me this, it is probably the same as the ktm's.

i'm not sure about your bike but for it to be as close as possible find a bike with the same size forks (dia) as yours and use that level. If the KTM's fork is the same size use that measurement.

Thats my advice or call JN innovations in hayward, ca and ask them if your nice they'll tell you
