    My SMR511 (2011) came like this brand new. The valve was just tucked up in the plastics.

    With the valve just tucked into the plastics it dribbles gas on the subframe, plastics, and silencer. Just curious from other owners if their bikes came like mine. Assuming not, can anyone tell me what the OEM routing of the hose was and where the valve typically resides?

    Also, if anyone has any good fuel catch tank solutions please post pics!

    The line would have originally been ran like this:

    On both of mine I just ran the factory hose up towards the front of the bike and then down into the skidplate pretty much down along the shock. One bike still has the vent valve and one does not. The TXC 449 had been upside down / on top of me multiple times in assorted sundry postions and I have never noticed any fuel leakage.

    I run my vented tank fumes to my air box on the clean side of the filter. This eliminates all gas fumes and keeps debris out of the fuel vents. If fuel is dribbling out of the one way valve, then it should be replaced and then re-routed to either the bottom of the bike or the air filter box.

    It looks like the hose that goes onto the valve is laying right there. Why don't you plug it back in?

    That's electrical. Not hose.

    Interesting. Any suggestions where I can find a through-panel barbed fitting to put on the airbox to attach the hose to?

    I installed this right next to the oil breather line. I get kind of whoosy from smelling gas out on the trail, so it worked for me. We have had issues in the past with dirt getting in the vent lines, but only while racing, never heard of casual riders having the issue.

    I decided to put the tank vent in the airbox on my TE449 after reading this thread but I am just going to use a valve stem off of a patched tube and some metal backed rubber washers on mine - easy and simple, already in my hands and at worst pretty much all I have to do is remove the core out of the stem and cut it off the tube. 1/4" hose fits perfectly over a valve stem as a 1/4" vacuum line from a running engine is a great way to pop beads on tubeless tires in less than ideal conditions (again after removing the core).
