General engine theory question pertaining to my scooter. I'm asking here because you guys are smarter. When I deleted my airbox I lost the connector for the PCV line that runs from my valve cover to the airbox intake pre-carb. Most people just run it up high and forget about it or use a catch can. I happen to have a spare vacuum connector sitting on my intake manifold POST-carb. Is there any engineering reason why I couldn't just go ahead and run the PCV into the intake manifold? Could it cause air mixture issues? Is there a reason not to do this?

Pre-carb is always atmospheric pressure (well OK really slight vacuum), post-carb is going to be under vacuum when the throttle closes. It'll vacuum up the the crankcase and you'll get a blue smokescreen. It'll be neato!

I assume you've put some kind of pancake filter or something on it? Why can't you just fit a takeoff to the underside of that for the breather?
