Hi Ian
A lot of head scratching has gone into where to put things and I needed to use every space with the strut brace, brake bias valve, Accusump extra fuse boxes, FI regulator etc. 1L is the typical minimum for track day scrutineers. I think I have 1.17L but will actually measure it with some water later today.
Using an old beer or coke tin is no longer well thought of. I have used old gear oil plastic bottles and cycle drink bottles with plumbing fittings before, but decided doing it neatly might be better all round. Lots of oil catch tanks for sale, but they are sized too small for the VX. The VX has a BIG breather needing 22mm ID pipe where as the 2000 Carb only needs 19mm. With 19mm I would have used A/N 12 fittings and could buy a cheap round catch tank that would not fit very neatly next to the battery.
I would have gone with 2x 45% outlets, but wanted to be sure to clear the Accusump.
NB Oil catch Tanks need to be higher than the breather so oil vapour condensates and drain back as much as possible. Inside my tank it is not straight through. The pipes cross so the vapour does not just blow straight through.
