it does look too small .. thanks Dr_C
the thread says they were using it up to 540cc
FWIW this is my breather filter on my 700, car fuel filter, quite restrictive and the ID of the fittings is 8mm
I don't have any problems with excess pressures but i have 2 reed valves between the main crank cavity and the gearbox. where there are 2x 8mm holes in total.
on my "new" engined 628 there is so little blowby it is hard to discern any outward flow at all even at 7 - 8000 rpm, it also has the 2 reed valves.
