Need to recharge the rear shock on an 1985 XR200. need to know the nitrogen pressure

The gas shock uses an extremely high pressure depending on the shock anywhere from 145psi to upwards of 200psi, they can be extremely dangerous causing serious injury or even death, so unless you have done this type of work before, I would get a professional to do the work.

This is not air shock it is a nitrogen filled shock that is charged with up to 300psi.It should be charged by a shop that does this

between 150-175 psi is normal range but should check in your owners manual it should list that information there or contact your local Yamaha dealership.

180 psi nitrogen. Your local suzuki dealer should b able to do this 4 u very cheaply.

You can change it. Im looking for the correct amount to do it myself. I already pulled mine apart and bought a rebuild kit for it. Comes with a new nitrogen bladder, o rings for the seal, and a few other necessary items. Just remember to measure where the jam nuts holding your spring is so you can put it back in the correct location. As for the nitrogen i heard 150 psi. I'm fortunate to work at an offroad racing shop so i'm just gonna fill mine with nitrogen there, but i dont think you should get charged too much at a regular bike shop. Rockymountainatv.com has the rebuild kit. You will need the seals atleast. If i find anything else out i'll let you know. Hope this helps.
