Due to request for info on how I re-routed my breather tubes, I took some pics to post and thought I would lay out some simple instructions on how to do it. Materials: 6' 3/8" fuel line (black stuff at your local auto parts store) 2 tees for 3/8" line Hose clamps Breather filter (custom parts section of auto parts store) Zip ties Steps: 1. Remove seat, air box, filter and base 2. Pull breather tubes from base and connect them to a tee (I had to trim one of mine shorter for a better fit). I also used hose clamps to ensure they stayed but could probably leave them off as its a snug fit onto the T already. 3. Take ~6" piece of 3/8" hose and run each end UP from the bottom of the base to plug each hole. Makes a U shape under the base plate. 4. I ran hose out under the seat where I placed another T. One Tube comes out of T and runs out the rear right of bike and is attached to breather filter, which is zip tied to rear brake line. Other tube runs down out back of bike and is zip tied between in the space between the muffler and the left foot peg. http://www.peterbiltofidaho.com/images/uly/under_s eat.jpg http://www.peterbiltofidaho.com/images/uly/filter. jpg http://www.peterbiltofidaho.com/images/uly/bottom. jpg I placed a bolt in bottom of drain tube to periodically drain spooge out though there are custom catch cans you can buy or make. I took the simple route. Bike definitely runs better with a noticeable decrease in stutter on line. A simple mod that I did with the 06 air box mod to get the non-combustible gases out of the air box, not to mention no more oil being shot into the airbox, which is what I found when I first took the airbox off. | ||

Why is the T'd breather hose (as well as the breather filter) necessary? In your set-up, wouldn't the spooge run down the filter/breather hose and into the filter thanks PS 'Nuke the Whales' (Message edited by johnboy777 on November 30, 2008) | ||

Here is James Laugesen's explanation: The breathers allow the engine to breath (so everything can move without imploding itself, basically  ) and vent blow-by gasses (gas which escapes past the valves, seals, rings, etc). The blow-by gasses are fed back into the air-box, so they are re-burnt and expelled through the exhaust (or collected in a cat, for example). Unfortunately the blow-by gasses don’t burn very well, and displace oxygen, reducing the engines potential power. So re-routed the breathers out of the air-box will give a performance increase. This link was helpful: http://jl.sg/articles/2007/08/04/06-open-air-box-a nd-breather-mod His is even more simple than mine; I collected guidance from several Buell sites on the web about rerouting the lines and went with what I thought would be a better solution (looks better too IMO).

In your set-up, wouldn't the spoong run down the filter/breather hose and into the filter] Spoog would most likely follow the most direct route and gravity. The breather line angles off and up before going down to the filter. No evidence of spoog there. I could have also just ran the filter to the back of the under seat by the tail light but then you couldn't see the trick looking filter. What fun is that? | ||

After all the oily spooge in my intake ports, I've done the breather re-route as well. Don't tell anyone, but my diesel car has the same mod. I figure at 50 mpg I make up for environmental damage. Interestingly, the Uly and my car get very similar mileage, both town and highway. | ||

Its not environmentally damaging if you drain into something and properly dispose of the spooge.  | ||

Froggy Posted on Sunday, November 30, 2008 Its not environmentally damaging if you drain into something and properly dispose of the spooge. Yes it is; unburned hydrocarbons are released to the atmosphere... BADDDDDD! | ||

Well I got a carbon canister on my bike so that makes up for it | ||

I'd like to think that I was doing my part to help warm up the planet, to make our winters a little milder here in Ohio  | ||

Thanks Armymedic, this is how I will do mine as well. You saved me a few bucks! | ||

I added the American Twin catch-can and find spooge collecting there all the time. I drain it every oil change in amazement to find what has collected there. It is vented to a filter then atmosphere also. Care must be taken to not have any low points in the head vent tubes where spooge will liquidify and prevent air flow. The rear routing of the vent tube shown here is a great addition. Thanks. ~jammer | ||

PS 'Nuke the Whales'  I almost spit my coffee all over my laptop. Thats FUNNY! | ||

I ran my hose along the left side and it ends behind the left passenger peg. It's actually wire tied to the fuel overflow hose. The filters are cute but there is no way any dirty air would ever get all the way up to your heads so why use one? Oh, they look cool. Ok, I'll buy that. I've alway set my HD's up this way and it does help the Buell run smoother. Our engines are so lean that anything that doesn't burn makes it worse. | ||

Hi Tootal, Did you just run 1 open hose to this location from the stock hoses tee'd together or run the same as Armymedic, i.e. 2 tees but with an open hose instead of the filter? Thanks | ||
| Treadmarks |
I ran the AZZ valve from drag specialties before switching to a drummer catch can.  It will let the spooge out and keep water/dust from going in. | ||

Did you just run 1 open hose to this location from the stock hoses tee'd together or run the same as Armymedic, i.e. 2 tees but with an open hose instead of the filter? I just ran one hose,(polyurethane because it's thinner), and it may drip while I'm riding but I don't see anything on the bike and no drops on the floor either. What comes out is pretty minimal. I guess I should be thankful for that! | ||

Went ahead and ordered the 07 inner airbox for my 06. I do like to tinker but I also like to be able to put the bike back to stock (especially when it comes time to sell it. Next I'll pick up the parts listed above by Armymedic. Thanks for the list | ||

Would there be anyone willing to gather these parts and send them to me small fee via paypal? I am stationed in Belgium for the next couple of years and besides the French to English language barrier I don't know if parts stores would even have the correct size hoses. | ||
| Midnightrider |
Keith Anything for a fire dawg! I plan to pick the parts up Saturday. It'll be no problem to pick up 2 of everything. PM me with your address. And do you want/need the updated inner airbox (07 and later) or do you just need these parts Materials: 6' 3/8" fuel line (black stuff at your local auto parts store) 2 tees for 3/8" line Hose clamps Breather filter (custom parts section of auto parts store) Zip ties | ||

Just one word of caution, although it shouldn't apply to motorcycles... I own a Volkswagon TDI (diesel) and the the crankcase vent ("breather tubes") also were ran into the intake manifold. Many of us rerouted this overboard as well. The oily vapor was mixing with the sooty exhaust from the EGR and plugging up the intake manifold. The concern we have in cold climates is that what comes out of these vents is oil and WATER vapor. Some guys in the northern climates had theirs freeze up and raised havoc on their engines. I live in CT and have 262,000 miles on mine and have run it in very cold weather (0*). BUT this is on a diesel engine, not an air cooled twin. I don't think this is a concern here unless you ride in very low temps. | ||

Thanks a lot Midnight. I only need the parts you listed as I have a 2008. I will pm you my address. When you add up what I owe you just pm me the amount and your paypal addy. Thanks | ||

Well I did Armymedic's breather hose re-route today and took a few pictures. After pulling the air box, etc. off I removed the front stock air hose. I bought a random length of 3/8" air hose from Harbor Freight last weekend for about $4 to use for the hose.  I relocated the short hose from the right under the wiring and T'd at this point.  I then cut another short length of hose and slipped on the 2nd T. i branch goes to the filter from here and the other to the drain line.  This is a picture of the drain line capped with a 3/8" bolt. I ran it inside of the passenger's mount held by 1 small tie passed through the bracket for the fuel overflow and another to hold it in place. You can't see it from the outside.  I bought a stainless filter at Autozone and with this I also needed a 3/8" to 3/8" hose coupler so add that to your list of parts.  .. and this is the way the filter looks installed.  | ||

Sorry about the small pictures in my post so here's another attempt. Well I did Armymedic's breather hose re-route today and took a few pictures.

I was also planning to cap the two airbox holes with rubber and steel fender washers but my 1/4" bolts need to be 3/4" long and all I had were 1/2" long. This will be a job for later today. I used a loop of 6" long hose like Armymedic did.  | ||
