Quick Coleman BT200X Gambler 500 Build

Can I ask about your breather hoses? Are any or all running on check valves by chance? Do you let your crankcase breathe in as well as out?
No check valves I have 2 crankcase lines venting to the valve cover and then a vent from the valve cover to the atmosphere. Almost zero oil escapes the engine this way. I used to run a catch can and even after a 100 mile enduro race it only had a few drops of oil in it so now I just run that line to the atmosphere a few drops of oil out of that line is no big deal
