recharge rear shock
 

I need to recharge my rear shock it has no gas in it. I was thinking I should change oil in it too. What kind of oil and weight is it? How much nitrogen does it take. I heard numbers from 240-300 psi. Is there a seal kit avaible. I have nitrogen, and the shock just threads apart so I don't want to play someone to do this for me. The dealer doesn't list parts for the shock so where do I get seals from. Its not leaking oil it just has no gas left in it.

Your dealer should carry fork oil. It comes in different weights. The heavier the oil, the slower your rebound will be in relation to the spring on the shock and old settings.

If I remember correctly, it was around 275 for the rear shock. The more or less PSI that you put in there, the quicker and slower the travel of the shock is going to be.

I am not aware of any rebuild kits for the rear shock.

Remember to get ALL of the air out before you put the shock back together, or you will have a dead spot in the travel.

This is a little off the subject but you seem to know a lot about shocks. On my 04 DS650 it noses down real bad in med - large whoops. I can fly over the small ones but the others and it's like the bike is being pushed from behind forcing the nose down. what is the proper adjustment to make to correct this, and which way do I go harder or softer? Even in jumps it handles fine but these whoops are killing me. it's the only plave my riding partners can get anywhere near me and I want to change that !

The dealer told me it was "rydefx slide hi-performance lube". This is what is was called in there manual and they didn't have any anyway. What weight oil is that, I can get amsoil, fox, and many others jobber but I need to know what to get first. I understand what going lighter or heavyer will do but what is stock so I have something to compare to. How do I make sure there is no air in the shock hose and resy. Thanks for any help and info.[img]i/expressions/face-icon-small-cool.gif[/img]

I checked with the shop manual. 300 psi is the correct amount.

The shop manual does not give the weight of the oil that is in the shock.

I would start with the medium weight oil and try it out. It is only 6 bucks from RMATV. Bel-ray 15w This is what I use and am happy with it.

cain73 It sounds like your rear suspension is set up with to fast of rebound, and transfering the weight of the bike to the front. It does not sound to bad, so what ever adjustments you do, do one at a time and in small increments.

Do you have a suggestion on which I should adjust first? Is it the rebound that is too firm or is it that it's not compressing enough (need to make it softer), or how can I tell? The dealer said that I just need to adjust the front to make them firmer, but that doesn't sound right to me. It's more like the back is pushing it down not like the front being too soft. Any further suggestions ? I appreciate your input.

If the back is pushing up and transfering weight to the front. The front will nose dive on you.

With you at the back of the quad, push down on the bumber and let go very fast. If the bike sits back up (springs back real fast) then your rebound is set up fast. If you push down on the bumber, and it takes two seconds for it to come back up, the rebound is set up real slow.

If I am riding through the whoops and the back of the bike bounces side to side, the rebound is to slow. If I am riding through the whoops and the back slaps me in the butt, the rebound is set up to fast.

Hope this helps
