You don't need to rebuild every time you change the oil. I only rebuild mine when they start leaking from the shaft seals, Otherwise if i'm just changing oil, just drain and refill. As for how often the oil needs replacing, it depends how much and how serious you race? Maybe every gallon or so?

I bleed mine a little different to the vid... Once i've filled the shocks with oil and got all the air bubbles out from behind the piston, i install 2 bottom spring retainers on the end of the shock shaft and push the shaft in till it bottoms on the second retainer. Then i top up the oil to just bellow level with the top of the shock body and install the shock cap with bladder installed by winding it on 2 turns. Then hold the shock at an angle with the bleed hole at the top and slowly turn the shock body into the cap. As you tighten the shock body into the cap, you will have a small amount of oil and some air bubbles coming out of the bleed hole. Once the cap is tight, remove the spring retainers and pust the shock shaft in till the ball end bottoms on the shock body. When you let go of the shaft, it should self extend about 10-15mm (1/2 inch). This will give you a rebound of about 30%.

There are many different ways people bleed their shocks. This is how i find to be the most consistant for me. The aim is to get your shock rebounds balanced left to right.

Hope this helps!......
