Rear Shock Gas Pressure

Since I have my swingarm off, I thought I'd have the rear shock pressure checked. With only 6k miles the shock shows no signs of wear but after 15 years I assume there may be a loss of pressure.

Anyone know the appropriate nitrogen pressure? Can any moto shop check/refill?

Any good shop with suspension specialist can service/rebuild the shock. Worth checking the spring rate too and getting it all setup for your weight

Just had My OEM shock re-gassed on my 312r and it's around 150- 160psi or 10-10.5 Bar. And Yep, you'll need a complete service as I did. My bike has done 27000 Klm.
As a side note for those with a 312r.....I was looking at replacing my OEM shock but in the meantime I thought I'd take it to a Suspension Tech and he re-built and serviced it for me, replacing the hydraulic preload adjuster as it was faulty(very common problem with the OEM shock)with a manual adjuster. Haven't put it to the test as yet but I can feel the difference pushing down on the back of the bike. Track Day coming soon though.
Point is, the OEM shock is of reasonable quality and they can be completely pulled apart and re-built/modified which in my case cost $200 as apposed to upwards of $1500 to replace. At my current skill level the bike was handling OK though a couple of 'Get Offs' had me focusing on suspension which is very interesting and influences so much of the bikes performance.
Sorry, diverting a little but the dark art of suspension is enlightening to say the least.....

Thanks for the info guys. I ended up taking it to Road & Track Cycles, a race shop, here in San Antonio. After some discussion (not me pressing the matter), mainly that it was fine, they found it a "little low" and gave it a shot of charge for free. I was happy as a peach.
