KYB Shock Oil Change | Yamaha YZ125/YZ250

In this video I show how I change the fluid in a KYB shock. However this most likely works for most dirt bike and street bike shocks. The shock I'm working on is very similar on the Yamaha wr250/450, yz250/450, and yz125.

I forgot to mention that you should always fill up your shock with nitrogen, the air shown in the video is just for testing purposes. Your local dealer or motorcycle shop should be able to do that for a small fee.

Hello!
very good video!
tell me something, what pressure do you put in the pre-assembly? I'm not talking about the pressure after it's done!

[@DirtPrimeADV]

U should have enough pressure for the bladder to take it’s shape. 10 psi should be enough (I went as far as 25) but I don’t recommend going that high as I have no knowledge on how much pressure they can hold in a non pressurized environment

[@justintschetter2363]

What weight oil did you use and how did you like it?
