Title: Re Gassing rear shock
Post by: thorns on April 24, 2013, 08:49:52 PM

Could anyone tell me how to tell if the rear shock needs re gassing?
Have just redone my forks with new springs, and put a new one also on the rear also.
Just wondering if there are any tell tale signs that the shock needs regassing?

What type of valve is fitted to remote res? If it's a shreider??(car tyre type) then simply use pressure gauge. If not, take shock out, pull spring off, fully compress the shock shaft, it should rebound all the way out again (make sure your rebound setting on the shock is set to lightest.)
Or just get it serviced, you'll know for sure then.

mx shocks should be serviced every 40 hours.  more often if your a fast expert.  trail you can go a bit longer.  chances are you need it serviced

Don't put a pressure gauge on a shock.  You will lose pressure quickly!!

There is such a small volume of nitrogen in the shock that when you check the pressure it will lose quite a bit. Plus, most of the shocks are at 150+ psi (ski-doo runs them around 300) The best way to check it yourself is to take the spring off and compress the shock, it should extend itself back out fully without any sticking or goofiness. You don't need to touch the valving to do this, just remove the spring.
