Fork oil quantiies - different per leg?

OM says

427 cc right leg
298 cc left leg

IS this right? Legs look the same (although I guess left leg has brake system on it).

Fluid recommended is a 7.5 weight. I'm planning on changing to a 5 weight.

Does anyone know if there are any drain screws on the bottom of the legs? I can't see any so I'm assuming I'll have to suck the old oil out.

Sorry to say but I think drain screws dissapeared back in the 80s.
Different oil quantities are because one fork does compression only and the other rebound only, can't remember which did which off the top of my head.
If you are going by quantity and not an oil level measurement then I think you would be better off pulling the fork legs off the bike and drain as much old oil out as you can, then refill with those quantities. If you suck the old oil out you will probably have some left in the bottom and end up with too much oil.

Let us know what difference the 5 weight makes when you do it.
