    Breather Location when running K&N Pods

    So for the last 12+ years I've run a small K&N filter on the end of an elongated breather hose routed back through the frame to the under seat area. It sits above the battery in a spray paint can lid that is fixed to a bracket attached to the old airbox mounting.... It has a rag underneath it which I change out when I remember, usually at oil change time as it doesn't collect a lot of oil.

    Anyway I thought I'd see what other people did as I'm currently working in that area..... show me what you've got!

    similar set up ... have a hoseclamp around frame crossbar under rear of tank ... with a pvc cap attached to hoseclamp excess-tab dangling down. Breather tube to the right length that sits inside.
    One bike has k&n on end of tube
    One just has tube into pvc cap.
    Never noticed any difference.
    Haven't noticed any need for rag.

      Long time no see!

      That location will probably suit my plans better so that's one option at least! Thanks mate.

          Maybe overkill but I put a 300ml catch can under the seat, it was $25 off Amazon and just fit.

            Do you “catch” much?

              There's a dipstick and I've checked after a couple 30 minute rides since I put it on, no oil is registering yet.

                On my latest GS1000 it has Ramair foam filters. On the end of the breather pipe I put a plastic T piece and a hole in insides of filters. The T ends are pushed into foam and any fumes from breather will get sucked into engine and reburned, hopefully.

                  You can also go "old school", even though it's VERY environmentally UN-friendly.

                  Just put a longer hose on the fitting at the top of the engine, run it along the upper frame tube (hidden) and run it to below the swingarm pivot. Cut an angle on the end so that it creates a bit of vacuum to promote vapor movement.

                  It's not really as un-friendly as it sounds, though. Your little filters on the end of a shorter hose only catch liquids, not vapor. There is some mesh at the engine end of the hose that should catch all the liquid in the first place, so it should ALL be vapor. It's just a matter of having one last place for the vapors to condense before hitting the atmosphere.

                    Where are you guys buying your PCV caps? I just ran a tube out the back of the bike but wouldn't mind capping it just for peace of mind.

                        Yeah I understand a longer hose is also an option... My does not breathe heavy by any means and the wire mesh is inside the breather plate.

                              A PCV (positive crankcase ventilation) cap is an automotive part, why would Home Despot sell them? Are you thinking PVC instead?

                              As for my question, never mind. I went on amazon and found they are far more generic than I realized. Pretty much any of them will work and solve my problem...
