I posted this inquiry under the KV, Engine- Breathers section, but haven't heard anything back: Anyone reroute an XB's breathers out of the airbox yet? I was wondering if there is any benefit in doing so, as I know it is a popular mod with the 1200's. | ||

The whole breather line setup on the new engine was/is supposed to negate the need to reroute the breather lines. Maybe someone needs to go look at the race bike setups and see if and how they are rerouting their breather lines. Not directly related since they are running punched-out engines, but might be something to check into none the less. | ||

ATT: Apexl *** The benifit is that you no longer pollute the intake charge with oil mist when runing the breather hose or hoses to a catch container!!!! *** Do the right thing and improve the product.. In buelling BUELLISTIC and/or Hardley-Harley | ||

Apex, I will pull the bike apart today and take a look at it. Most move the breather lines because of all the oil the gets pumped back into the engine. Buell put some kind of shield in the engine that helps keep the oil down lower and not up the breather lines on the XB models. Even the blast doesn't have the shield. Someome posted a picture from the manual that shows the shield a few months back. So far I haven't found any oil in the airbox.... | ||

I found some oily residue in my breather box after about 700 miles on my XB9R. Not much, just a film that was oily to the touch. | ||

Hope this is where this belongs... I got the XB9S with the race kit installed... I hear that it needs to be "de-snorkled"... What I need to know is...how?  They didn't do it at the shop. Any help will be appreciated... | ||

The rubber hose that vents the transmission on XB's is quite long. It goes from from the back of the rear cylinder all the way to the battery tray area. I would like to shorten this hose to get it out of the way. Is there a need for such a long hose? I would imagine the vent has to do two things: vent gases out of the trans and be positioned so that water can't get in. If this hose is cut off about 3 to 4" long and positioned like an inverted "J" would that pose any potential problems? Mike. | ||

To xb9er: I'am not sure of the tranny vent tube... does it now (stock) have a section that goes vertical (back up, instead of just downward?) Guys, let me know, but I wouldn't make a "J" or a return back up from an originally down vent tube. It may negate the vent and trap liquid in the bend... }}To the rest... concerning the crankcase vent... that's simple... not only does it "vent" hot air back into your airbox, but also coats everything in an oil mist. I have spoken to Al @ American Sport Bike and he stated that there is a decrease of about 3% HP by returning this air into the airbox... and our bikes basically have 100hp -- well, that's 3 HP by just re-routing the vent tubes. Buell (and other manufactures) have done this for EPA reasons; clean air acts and he like... Just take the inner airbox off, you'll see the two breather hoses... connect with a "T" and re-route the (now) one tube to the area beneath the chin spoiler... use catch can or K&N style vent filter... and that's it. happy riding robert | ||

i ran my vent hose back to the swingarm, wedged it in a gap with the upper chain guard, the (infrequent) drip after shut down lands on the drive chain, where it is quite welcome. |
