Interesting discussion on the crank case breather. I never gave it a thought until I bought my Ram Air kit. What to do with the crank case breather is an old Triumph and Harley problem. On my 650s it used to run from under the engine and back along the top of the fender to the rear. On my shovel and early model Evo, the hose just hung down, creating the oil mess. With the early model Evos the vent hose went up into the intake which had a sponge substance as an air cleaner. It became an oily mess fairly quickly and had to be cleaned, which is why I changed over to a Screaming Eagle intake and routed the line to the underside of the frame in front of the swingarm. I even kept a small filter on it like the one that comes with the Ram Air kit but a lot of that stuff still gets out. Harley fixed that with vented heads, where all that dirty, lower case oily crap is routed into the heads. I know, this is the way it is done on virtually all bikes now and it is EPA compliant to feed the vented back into the engine. Apparently with Triumph, it goes into the air intake.
Hmmmmmmmm. IF I install the Ram Air, I'll initially leave the crank vent hooked up to the original air box and probably put some type of sponge filter in there to catch any oil mess. I'm sure it is probably not as bad as the old Triumphs and Harleys, especially since the tube can be tied into one of the trip K&Ns without any issue, but I'll just watch it for awhile to see how it goes. I'm sure when I open it up to do the Ram Air install I'll have some kind of blinding flash of light and think of a proper fix.
