I always build mine this way:
- fill oil untill about halfway
- push piston up making sure it doesn't come out of the oil
- pull down slowly(!) so the air bubbles rise up from under the piston
- Fill to about 3mm from top
- push piston all the way up keeping it in the oil
- fill up with oil so that it's flush with the top of the shock
- put two drops into the cap
- assemble quickly 
- see how it feels and if it's too stiff undo the cap about 1.5 turns and push the shaft in to bleed the excess oil out
Job done.
Haven't tried the bleeder caps yet but the old ones work fine too. |
I have an even easier and quicker way than that.
With the piston down, fill the body so that the oil is just reaching the top of the body, with a concave meniscus (the oil looks like a bowl). Stroke the shaft up and down to get rid of any big bubbles and top up if necessary. Moisten the cap with a drop of oil so it makes a good seal, screw it on, job done.
A correctly built shock will not stiffen up as you compress it, and may have a tiny squeak of air at full compression. It will probably rebound about half the stroke, slowly - this is normal because the air tries to recover its normal pressure.
If it stiffens up under compression - too much oil. If it has a big squeak and you can feel a dead spot at the top of the stroke - too much air. If it tries to suck the piston in from full extension - too little air.
