My YZ 250 F rear shock absorber fluid and nitro amount

The service manual just says that if it leaks any oil to replace it.

go get the wrench for it

if it has an adjustable coil shock on the back u should be able to turn the collar on the botom of the spring to tighten it up, somtime's there is a spetial too needed

this needs to be done by a professional

how do i check my oil level on my yz 250

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.
