Crankcase breather connection to twin carb setup

Hi Guys - I’m building a Pembleton 3 wheeler with a Dyane engine and twin Honda carb setup. I have refitted the Reniflard crankcase breather / filler due to oil leaks/ crankcase pressure issues. I know on the original single carb setup there was a connection to the air filter. I intend to connect the the twin carbs at each individual air filter ( with hoses each half the crosssectional area of the connection on the breather. Would this affect operation? Would I require non returns in each limb? If so any suggestions would be greatly appreciated. I’m just trying to preempt any problems?

In addition has any one tuned these Keihin VB30 carbs (Honda). What mods did you do to the carbs besides the Pembleton manual suggestions? I understand there is a Honda carb guru called George Stephenson, who isn’t active at present on the Pembleton forum. Hopefully he is active on this site. Again any assistance appreciated? Cheers Steve

When the gasses leave the reniflard I would just run the pipe down to a small collecting bottle also in the same pipe I would fit one of steve parishes non return valves …
