It still needs to off gas, the rest of line is for the condensation and other liquids. You are right, probably not all the nessesary, but I do like the idea of the negative pressure extracting gases from the case but allowing the condensation or fluid oil to escape rather than recirculate into the intake. |

I fabbed a stainless catch can with two fitting on top and a drain plug on the bottom, mounted it to the left of the oil cooler when your looking at the front of the bike, then breather hose into catch, breather hose out to a HD crankcase breather filter. used automotive smog line fittings for making 90 degree angles. came out clean and very functional. |

I did mine about a year ago. At first with breather filter tee'd off half way down and run out by the swingarm but the filter started getting spooge in it. I rerouted a single tube down the left front of the bike down into the hole in the fairing. No breather filter. Runs great. Not a lot of spooge. Much better running engine at low RPMs. A great mod. I wouldn't plug the end of the hose though. Quite a bit of gases coming out of that. |

After being suspicious of it making any difference, I did it as a temporary test. I it does run smoother. I say try it. If you don't like it, change it back. No catch can or filter. |

I was about to do this mod and noticed a HUGE amount of oil/spoog around the valve on top of the cylinder head. I hadn't really noticed anything but as I looked there is crap running all the way down the heads, on the cables running through there and it is on the bottom of engine case. Is this a normal part of the blowback? Or are those valves not fitting correctly? Front valve has some spoog but not nearly as bad as back. thx for any input Brad |

check to be sure the pcv is seated. |

thx rwcfrank. I can lift it up very easily with fingers, until it hits the metal bracket above it. That is the only thing preventing it from coming off when I pull on it. it moves side to side like it doesn't fit. I will take pictures tomorrow in the light if that helps explain better. what do i need to do to seat it? Never had a spot of oil in 15k miles until now and has run all over back of engine. That being said, any suggestions on cleaning spoog off. simple green or something stronger? pressure washer? Thx |

Pauley2000, I have not been ignoring your question but I was on a short motorcycle trip Friday afternoon through Saturday evening. I rode to a motorcycle show in Milwaukee,WI and put 630 more miles on the bike. The night before I left, I updated my breather mod using Andymnelson's recommendation. The bike does actually seem to run better at low RPM's with the original breather mod and I am quite satisfied with it now. I think it runs well enough that I will not pursue any more updates to it. I got just slightly over 50 MPG on one tank of gas on this trip and averaged 44 MPG. Also, no more hot oil fumes with the last update, thanks to Andymnelson! One thing that does concern me is that I am only getting a very small amount of condensation in my catch can which consists of a foot long piece of clear vinyl tubing with a petcock in the end of it. Some of you report a lot of spooge but I have almost none, so far, and I'm not sure why. Thanks. Original filter location:

Got done with reroute yesterday, went on 400 mile ride through the Washington Cascades, checked hose at every other gas stop and only had maybe one drop of oil each time? Some videos show quite a bit more after just 30 miles? 09 XB12XT. |

Just did mine last night. OMG! I cannot believe I didn't do this mod from the git go! Bottom end suddenly started to prove itself. Much smoother operation, less buzz, more power. This is one of the oldest tricks in the book, but I didn't see this dramatic of a difference in the past. I run amsoil and synthetics do not burn as readily as fossil oils. So there is a well tuned computer trying to figure out the burn. No issue now. Highly recommend this mod. |

I did it a few days ago, and I noticed a difference, even after changing to an Erik Buell Racing ECM a couple of days before. I have a stock '08 XT, and it is now a completely different bike. It runs so much better now that I may not add the 9 primary. Maybe... |

Stupid question, but after spending the morning riding to various parts and hardware stores (sunny and 80, the ride was sooo tough!) I cannot find brass 3/8 tees. I worked in auto parts for years (20+ years ago), and there used to be drawers of the things to dig through- now they couldn't even find 'em in plastic- WTF??? Anyway, where are folks here finding the (preferred) brass Tees? Thanks! -Mike |

I used the plastic ones, had to buy the multi pack to get one. Only a couple of bucks tho. The plastic ones are fine- they are meant for under hood temps. |

Rarebird, I found my brass tees in the plumbing dept. of my local ACE Hardware store. They were not cheap but I know it is done as well as possible. Andymnelson may be right though, plastic would probably work just fine. Most everything else in that area of our bikes is plastic anyway. Plastic tees can also be found in almost any hardware store's plumbing section. Thanks. |

I found a brass tee that looked like they cast it as light as possible. If you get a heavy one dremel the tar out of it before you put it on, or you will always know that you are lugging around that extra weight. |

Ace, NAPA, Autozone and Schucks to find all parts for re reoute...aparently brass fittings are hard to come by nowadays. |

I was in a Sears Hardware store today, and saw the Tee`s for 3 bucks and change. Maybe a plumbing supply house would have them also. |
