I changed mine just before going to WVBR V. I did it mostly because the hoses were feeling gooey and rotted. I noticed no difference in performance.
On that note, those who have noticed a difference in performance, I have a question for you. Did you look closely at where the hoses were originally routed? As the owner of an '06 with a crazy amount of wiring problems over the years, there were two places the wires on my bike were compromised by the original hoses.
One was on the front hose where it crossed the injector wires. With heat and vibration it had worn them to bare wires. The rear hose laid on and compromised the ETS wire pressing it into another wire.
Is it possible that relieving the pressure on the wires the hoses laid on or rubbed is making your engine run smoother?
It is something I changed the original routing under the box for a few years ago. |

A lot of folks never drove cars of the '60s so they don't know what the total noxious fumes from an engine can be. Prior to Positive Crank Case Ventilation being around a hot running engine could leave you breathless. Of course that included a carburetor venting raw gas before charcoal cannisters and later recycling fuel vapors.
I owned many old 283s and 327s that simply had a vented oil filler cap and a drain hose off the back of the block that hung down by the transmission. Spooge was the same then, but rings did not seal as well, there was lead in the gas, and everybody's garage floor had an oil spot no matter how sealed up the engine was. No leaks, but a wet spot none the less.
Do you recall, or did you read about SMOG in the cities of the World? That bit of oil spooge stink was part of it. As well as the fuel tank vent. And the non catalyzed exhaust. The weak spark of points systems did not help much either.
I'm thinking about letting the spooge drip onto the very back of the muffler in front of the rear tire. That will evaporate the water and should burn off the minute amount of the oil. If it stinks, as in not hot enough to burn it off cleanly or efficiently, I will probably put it back in the airbox. I have been thinking about letting it drip into the exhaust flow inside the pipe. |

That hose off the back of the engine was actually metal and was called a "breather tube". The end was cut at an angle with the idea that the wind under the car at speed created a slight vacuum, helping to pull the vapors out of the engine.
And no, Vern isn't the only old fart here. |

Now I'm thinking I may change mine back to stock, after all.

I returned the breather on my 08 XT back to stock and went for a 220 mile ride yesterday. I have to admit, I think I could feel just a very slight surging at a cruising speed of 55-60 mph, which it used to do when brand new. I really had to pay attention to notice it and still am not sure. Maybe I got some bad gasoline?
Otherwise, nothing else changed. It seemed to run just as good or better around town and acceleration seemed even stronger, but maybe I was just imagining that.
The best part of returning to stock? No hot oil fumes at all. None. I think I will leave it as is. Thanks, great discussion guys. |

I ran my breather tube down the front to the top of the exhaust, it leaves a small oily spot on the exhaust can but doesn't drip to the floor. Not smelling any fumes. But certainly getting steadier running at the off idle RPMs that I run at in first gear on tricky sections of dirt roads. |

We might finally have a cure for the dreaded Uly exhaust rust! |
