KDX 200 Rear shock psi?

[ButcherToolz]

Hi all,

When I bought my bike the guy said he likes to ride with the rear shock soft however I want it stiff. Currently it feels way to soft (but not busted).

I pumped up my front shocks fine however the back shock has the little steel cannister attached with a valve and I attempted to pump it up a little but it wasn't doing anything.

Any ideas on the pressure it should be at?

Cheers in advance.

I use 140 psi in mine but depending on the track I can go to 180 depends what you want the back end to do !!!

I thought the KDX has seperate compression and rebound adjustment so you shouldn't need to pressurise that at all.

there should be one dial at the top of the shock and one at the bottom to do the adjustments

I assume he is talking about bladder pressure .

It's ment to be filled with nitrogen! I don't think you should be touching the pressure. Get a bike shop to charge it up for you! You can adjust the dampening with the adjustment screw on the side of that "little steel canister" this controls the ride hardness quite a lot!

Unless the rear shock has high speed and low speed damping , adjusting those screws will only change the low shaft speed behaviour of the shock , noticeable over shallow widly spaced whoops . accelarating /deaccelarating etc .
I didnt read ..( no it failed to register) ....that you tried to use air?? air CAN BE used to rebuild the shock ONLY ..u can ride it if you want but airs ability to handle heat is limited and the pressure will build up ...and the very least the valve /seals will pop ....Dont go there girlfriend !!!
Take the shock to a dealer, get the oil and bladder refilled ...IF there is no bladder pressure ,,,then the seals will need to be looked at ..like my shock !!!
The valves on the front forks are to release built up gas pressure ,,, I do mine after every race ...
The oil and its level will make a big difference ,,,I use ATF in the gearbox , front and rear shocks (the gearbox oil is ONLY good for one race )

They really are a good bike ,,,hope you enjoy it

It should be charged with nitrogen, if you pump it up with air it will mix with the oil and the shock will go rock hard after about 5mins riding, take it to a bike shop, its about $30 to get them recharged, and they will tell you if its worth doing or not

I used to have a kdx250 which started doin the pogo styles on the woops due to seal breaking. Cost $250 for a service, new seals, oil, bump stop etc. The bike was like new to ride afterwards tho!! Worth the effort!
Ohh how I hope I don't have to do that to my Ohlins shock on my TM, guessing that'll cost a whole lot more!
