Good grief I'm slow![img]i/expressions/face-icon-small-blush.gif[/img] I just figured out why you are asking this question[img]i/expressions/face-icon-small-wink.gif[/img]
I think breather capacity has more to do with how much blow-by you have, not displacement.
A 650 that needs rings will need more breather capacity than a new 800..............or a 720 that gets out of round due to insufficient cylinder wall thickness and bracing will require one hell of a breather to keep oil lines from popping off eventually.[img]i/expressions/face-icon-small-wink.gif[/img]
My $0.02

Does any one see a problem with running the crankcase vent tube to the intake tube (between air box and Carb)? Like the stock carburetor slide breather line.
Thanks

All of my stock bores blow oil out the vent like crazy. I have had a catch can on all of them, but it still made a mess. So now I just run a line up and over the radiator and back down below the machine.
Our two brand new engines both blow oil out like crazy. I think it has as much to do with the bumps as the blowby. IMO!
