How many PSI of nitrogen should I have in my rear shock?

I just changed the spring and I could not find the PSI in the manual. ANyone know how much goes in there???? 2005 WR450f THANKS!

no yamaha manual will state that because no manual will tell you how to take it apart. use 150psi

i think its 145 psi but i not totally sure.I have done that with a friend last winter but i cant remember exactl. Im pretty sure someone else will have a answer.

It needs 140-150 PSI. All good numbers reported so far. WR Dave
