I tied my vents to a “T” inside the air box. Then ran a single hose over the trans, along the frame, and secured to the rear tie down loop under the RT axle. This vents ALL the vapor out under the rear and away from the bottom of trike.
With the hose draining at the floorboard I was still getting a “mist” of oil on the bottom of bike even running 1/2 qt low. Not a dripping mist, but a fine coating that was bothersome.
Now, nothing on bike, well a very small amount on RT rear frame next to exhaust and that can be wiped off with a Kleenex every couple weeks.
