Happily the 2013 comes with a separate oil drain plug. Well yes we still need to clean the filter screen where the PITA oil vapor scavenge return hose barb fitting is, but it doest really need to be done every oil change.
OK so on the 2013 TXC310R, I leave the OEM hose arrangement for the valve cover breather hose as is into the "catch tank" (frame center section).
I leave(left) the breather box /catch tank (frame center section) oil drain return line down to the oil pan barb fitting in place, this is a nice touch for oil blow by, upside down bike spillage and oil vapor condensed to be re entered into the pan (unlike my 2011 TE310 in which I eliminated the return line and installed a TC250 oil drain plug and an auto motive vacuum plug off cap with a ziptie onto the frame center hose barb.).
(So) My only real change to the TXC310R oil vapor/breather system is that I removed the air intake boot line and ran it down to the front of engine behind the skid plate upper mount with a K&N crank case breather filter ziptied on (same as my 2011 TE310).
And, I had a nice perfectly sized solid alloy machined rod stock plug in my misc parts drawer that went into the intake boot bung (that sounds weird) with some 1211 threebond and an added ziptie for security(same as my 2011 TE310).
I dont like having crankcase oily vapor hot air entering my intake, I think clean "cool" freshly TwinAir filtered intake air is better for both performance and to keep all that oily vapor filled fouling air out of the intake tract.
Engine can still breath its crank pressures and suctions as engineered but without moving that air into the induction system (the volume of the frame center/catch tank also allows for good unrestricted air movement).
PS nice coincidental thing, the down run hi point hose to the K&N filter is the perfect length, no cutting needed.
