Dunno but my 5l Rover has 2X 50cl plastic orange cartons and they only show a mm or so after a run and the Rover was built with "wide"
clearances. Whatever fits I guess 1l sounds awful big.
You'd be surprised how quickly the sales people at B&Q try and assist you after ignoring you for the past 15 minutes when you try and start a

If you are into racing as in more then just a track day (MSA wise), I think you need minimum of 1 litre, otherwise what ever you can fit.

Found it in the Sprints hill climb and drag section
10.3.5. Oil Systems – Catch tank capacity – minimum
one litre.

If a bike looses mmore than a litre, then its probably going to be followed by the the pistons exiting the block, so 1 litre is more than enough IMO.
In RGB we are all supposed to run 2l, but most cars don't have them this large and its very unusual to have anything in them after a race
anyway.

Wow if you are into Circuit racing as MK9R mentions in section Q we have:
9.9.2. Have any engine oil tank breather or overflow
tube venting into atmosphere, led into catch tanks
which have a minimum capacity of 2 litres. For engine
capacities in excess of 2 litres the catch tank capacity
should be 3 litres.

Yeah it states 2 litres, but 95% of us have smaller and never get picked up at the scruitineers

A 1 litre bottle (aluminium drink bottle from Millets or equivalent) come nicely made in a choice of colours and is about £2 and easy to modify.
My engine is 15years old and has already had a life and I have only accumulated 2mm of stuff in there (oil and water by the looks of it).
How does a crankcase breather work with a dry sump? Do you have a valve to keep the crankcase pressures below atmospheric for the bhp gain, or is that
a bad idea?

Some connect the breather to one of the scavenge inputs on the pump.
