Oh good point hahaha. I didn't really think about that lol.if you plug the other tube end then it will just come out the filter screen.........ask me how i know?
The other thought is a small bottle strapped to the spine (below the seat), then the tube from the motor feeds the bottle and the bottle has the filter breather on top, that way the oil gets trapped in the bottle
I like the bottle idea, however I don't have a lot of room left in the middle of the bike anymore due to all the wires and tubes. But you have given me some good ideas to go off of. I might try and see if I can get a hump in the tube from the headers so it drains back down into the engine, or I might end up just routing it so the oil drains out past the side of the rear tire. But something to catch the oil might be the best option.
Thanks for all the help Kam!
