Hi,
We have the first section of the oil breather sorted (VANs supplied rubber hose) and have a number of options with the remain length AL, rubber, combination of the two.
What are the pros/cons of putting the breather exit in trail, vertically down, should it be straight cut, angled, should it finish behind the cowl lip?
Are we aiming for a positive pressure in the crankcase or a slight vacuum? Any performance gains one way or the other?
Trying to understand the function as well as the installation,
Carl
