hey guys does anyone know how to regas your rear shock absorber.
how many psi, can you use air instead of nitro and how much are new ones just incase?
cheers.

 

I doubt that air instead of nitrogen would be good, might even be unsafe. Nitrogen is an inert gas. Air can contain anything and everything reactive.

 

The stock nitrogen pressure is about 150 psi. The "how" to fill it involves a high pressure nitrogen bottle with a filler hose, closeable fitting, and guage. Just take it to decent motorcycle shop that has the bottle. It's usually an inexpensive service from most shops. You can use air instead of nitrogen. It's not as stable in different temps and air is not as "dry" as nitrogen. The shock piggyback and bladder like a dry environment.

 

Many car tires are now filled with nitrogen. If you cant find a bike shop that can handle it maybe an auto service center. I would stick with the nitrogen, one way or another.

 

Question: Why do you need to add nitrogen? Did you release what was in there or do you just think it's low? If you didn't release the pressure but feel that it's low, it may be a good time for some shock maintenance........disassembly, clean, and fresh fluid. Maybe even revalve it.

cheers guys just been having a bit of trouble when coming into corners and over some big braking bumps and the rear is bottoming out.
guess i should have asked what the causes are first.

 

If you are like me and weigh around 200lbs, than that is kinda of normal on the KLX. Kawasaki built the KLX towards lighter folks. A heavier spring will be the best solution towards the problem. The shock only controls how the spring reacts, which is to not create a bouncy ride.

 

Yeah, there could be a combination of issues on your KLX. Depending on how much time is on your KLX, as Brewster suggested you could need a shock service. Also depending on your riding style and your outfitted rider weight, the 5.8 spring might be on the light side for your needs. I revalved my rear shock and went to a 6.0 spring with excellent results. If you need shock service, it would be a good opportunity to get it revalved at the same time. It's a fairly amazing transformation that's worth the money.

 

thanks for your input guys.
much appreciated.
