How much nitrogen on rear shock ?

Hello everybody

I hesitate to prepare my suspension by a professionnal.
But for the moment maybe I would just rehabilitate my rear shock absorber
I make supermoto on track only.
I have already remade my fork last year

For the shock I can't find how much need for nitrogen inside?

If someone have already make a rehabilitation and have advice it's could be great

Great ride and happy new year for all

From internet so no guarantee...
"The 650R rear shock can accept pressures up to 250psi in the desert - I run 200 with the 10.5kg spring bc the spring is too strong for me but the 200 helps reduce the rebound. Otherwise I would use 230 if I weighed 30lbs more. Obviously low oil viscosity contributes to the leak. "
Happ New Year

Thanks for your quickly answer and your search
I had found nothing on Google... I had make a bad search, sorry

On your bike Mauser you have the OEM parts ?

I forget to tell my weight, I am 80 kg for 1 meter 80

Someone on this very forum mentions a book value of 142P.S.I.
IIRC, I put 150 P.SI. in mine when I rebuilt it

Thank your for the link
You have put the nitrogen you or a professionnal ?

I had found this on Google

Maybe 200 for SM and track ?
300 is to much :O

I've found the information on the shop manual.
The rear shock need :

981 kPa (1O kgf/cm2) of nitrogen
So 142 PSI

For the oil they said 'fork oil' ...
Fork capacity : 637 cm3
Fork level : 120 mm

I've found an other technical file.
They said SAE 5W.
I've put 10W, but for a harder suspension maybe 20W no ?
Kayaba is apparently very good. A guy who work for Ohlins had said this on a forum like a lot of members.
