DR650SE Rear Shock Gas Pressure
 

Just got a 2005 DR for my partner which has very little/no rebound damping in the rear shock. It is less than 4000mls old and appears to be in good condition. No evidence of oil leaks at all. It has a schrader valve under the remote reservoir. What goes into this? Is it just air or is it nitrogen or something similar? Does anyone know what pressure the gas should be at? I am thinking that if the gas bladder is empty it will effect the rebound damping as the oil will also not be under pressure. This is only a hunch cos I think I am venturing in the land of knowing very little of what I am talking about (not unusual).
Thanks

There's no rebound adjustment on this shock.

Sorry, no info regarding pressure.

Its Nitrogen and its on around +/-150 PSI, take care what you do, also the bladder can be broken.
Send the shock to an specialist to give a good service. Oil, gas, seals, bushes change.

If you don’t find anyone there, I have a good one here not far from me…hehehe:D
Catch you later on Skype.

You can check this yourself by putting a tyre pressure gauge on the valve or even just push on the centre of the valve to see if air comes out. Nitrogen is the prefered gas but you can use compressed air just like inflating a car tyre,in fact I used to use air in my shock on my motocrosser when racing in Saudi, nitrogen not being readily available. You can inflate yourself, it is just like putting air in a car tyre BUT you must have a gauge to check the pressure and the supply Must be regulated as with a compressor.
I have fitted a bladder in my rear shock but I had the use of workshop equipment and it was not an easy job.

Ta for the info
 

cheers for the advice guys. I will check it has pressure in it with a low volume high pressure mountain bike shock pump. will fill it with air if it has no gas in it to see if the damping starts to work, then send it off to a shock builder to repair and charge with nitrogen. oh and it does have adjustable damping! Javier why dont you come over for a holiday and you could sort out the shock while you are here! weather is really nice up here in the north of england at the moment. LOL
suerte
