Trust me youl know when you do it you cant take it out and do it because you need the spring in to put the nutt back in the bottom .
Secondly you cant take off the top bit without getting it back on which will then lead to taking out the whole thing which means taking out the bottom screw = loosing all your oil again!
we are just going to screw it all up and where the bleed screw or air screw what ever it is we are going to syringe it in that way ... which goes through so i wouldnt bother taking anything out apart from the nut at the bottom , maybe you will have to loosen the top nut so all the oil comes out but dont take everything out theres no point..plus you have to move your bars back .
