I had to read that about 4 times to work out what you're saying, but I think I've worked it out. I don't have the answer 100% correct, but I know GMP knows the answer.
Basically, you're asking which nipple goes where for the rubber tubes which run from the cylinder. The one of the left hand side is the drain for the powervalve. The one at the top on the right hand side powervalve cover is the vent for the clutch and gearbox. I believe the larger hole'd nipple goes on the right hand side (but thats just from memory).
