Take two
Cozz, I ran 1/4" 90 degree elbows from both breather bolts behind A/F next to front pushrod tube, venting side by side out of frame tube below oil filter. I cut both lines below frame at an angle to draw crankcase vapor out of tubes at speed. No sludge in lines after a year of riding. Yes two separate 1/4" vent tubes side by side out the bottom, no catch can or filters. I used zip ties at all clean connections. It is subtle.

I had weed whacker fuel line but the neoprene hose the local h/w store offer might be a better fit.......guess I pick up some 3 -4 feet.......1/4 inch the way to go I guess.

This cost me a little more than I expected, the k&n a/f I got on flea bay was over sized not allowing me to install the breather bolts, so this one cost me 8 bucks for the hose an clamps, then bust out retail for the right filter! (its an se 1 throttle body).

Rockey, what I did is ran a straight 3/4" piece if hose from the breather bolt to a 3/16" plastic 90 degree barbed fitting pointed down. That routed my hoses straight down and close in and away from metal cover. I used the small zip ties at the connections (4) and trimmed off excess. Clean set up. I did this about a year ago, no leaks and don't even notice the rubber lines. I did route mine forward along the pushrod tube down through the frame.

I am going to do the breather mod this weekend to my Ventilator. I am using brass push-on hose barbed fittings that I ordered from McMaster-Carr part # 91465K11 and push on hose # 5283K31. With this setup you do not need hose clamps. But you have to use that fitting and hose combination. We use these in the plastic injection mold industry all the time on our molds. The hose does NOT come off, in fact you have to cut them off for removal.
