So, tired of the oil going into air cleaner box on my V7 III, going to add a catch bottle. Do you think it needs to have an exhaust port, hose or filter? Or can it just blow into a small bottle with only no outlet in case of pressure build up. I was using a Magnum tuning bottle, but it is too big. I'm planning on a small bottle about the size of a front master cylinder. And yes, I regularly keep oil level constant with 1750 ml, so not too much.
