huh, that is a cool idea! Never thought of that. When I make my breather box, I'm probably just going to do a two piece deal. Then join the two pieces with more CF and resin. Or atleast that is how my brother-in-law told me he made the fuselage for a project in his aero. enginneering class in college. Did you put any thing in the middle of the box. Don't the ducati ones have some type of netting to catch the oil and the box has a downward slant back to the engine so caught oil can go back to where it came?
strati - bike is moving along nicely and this looking great!

What else do you have to do besides assembly when all the parts make it back to you?
