I know there is a whole bulletin just on the breather reroute but pics of how you guys did yours would be greatly appreciated. | ||

Thank you very much very helpful. | ||

Poppin, how do you have your K&N attached to the bar? I see zip ties going around the filter, but can see behind it. Is there some sort of bracket? | ||
| Poppinsexz |
No bracket, I just wrapped two zips loosely around the breather and bar, then I put another set around the zips between the breather and bar to act as a spacer. then tightened everything up. Holds up great. Hard to see but if you look at the back of the breather you can just make out the lock of a zip tie between the breather and the bar Hope that makes sense. | ||

I ended up doing about the same routing on my 12. As to the K&N, I took a short piece of left over breather tubing, and ran the zip tie over the frame tube, into the hose, over the K&N tube, and back through the hose. Makes a nice stand-off. | ||

That billet catch can is so nice. Looks like an OEM part. I've still got to get some armor for my knees before I get the can. Thanks for the pics. I'm going to down load them so they don't get lost. My only thought is; maybe hiding the filter up in the beast, let it vent in the cooling air that goes out the fan/rear of engine. | ||
| Poppinsexz |
I thought about hiding it too, but decided that I didn't want to deconstruct the machine any further, plus less hose = less weight, I also thought about airflow restriction and that it will need cleaned from time to time. The catch can came from American Sport Bike It does look OEM but it's a little pricey | ||
| Boney95 |
Poppin, thanks bro! You were clear in your description. | ||
| Poppinsexz |
No prob, good luck and take some pics when you get it done | ||
| Boney95 |
This is where I currently have it located. But I think I want to show it off a bit.  | ||
| Poppinsexz |
Thats a neat spot. well hidden. Some may not like it. but I like the look of it mounted on the side. | ||

Rather mechanical looking, but it works for me...   | ||
| Jraice |
For those of you doing an open system (no catch can). Two questions: 1: Did you have a filter or just a single tube open to the air? 2: Where did you vent it to prevent it from getting near the rear tire? | ||
| Krueger08xb12s |
Is it just me or does everyone else have super-smelling exhaust vapors from their rerouted air-filter? | ||
| Poppinsexz |
I haven't noticed any smell from mine. BTW nice use of a fuel filter. Jraise, Open to the air might also let it suck in dirt. | ||
| Jraice |
I know open tube has be done before... I think the general idea was that an oil lined tube that is several feet long wouldnt be able to suck air up, it would get trapped and also some people said harleys were done this way for many years in the past. | ||
| Poppinsexz |
All vehicles had this set-up many years ago; however they weren't at the performance and tolerance levels that we are today, and engine life was relatively short as compared to today’s expectations. Anytime a piston is going up in the cylinder it is creating a low-pressure area in the crankcase that will draw in air through the breather. So the potential for dirt entry is greatly increased without a breather. | ||

What is the purpose of the reroute? | ||
| Cyclenut80 |
I run an open tube setup on my bike and my reasoning for this comes from my off road experience. I have had several dirtbikes and three and four wheelers that run an open breather setup. I figure if an engine can survive in an offroad environment constantly exposed to dust and dirt then my XB will be fine. On top of that all the diesels in the concrete trucks I drive at work are open breathers and they live in quite possibly one of the worst environments on dusty dirty job sites. Not trying to flame anyone or start any issues just my opinion. BTW, my tube (with no filter) runs down near the left footpeg like Boney's setup and I have had no issues at all with it. | ||
| Poppinsexz |
Superman, Combustion gases that leak by the rings and into the crankcase are normally directed into the intake. These gases take up space that would normally be used by more fuel and air. The reroute takes those gases out of the engine, supposed to improve idle and engine response. | ||
| Poppinsexz |
Cyclenut, All the 4 wheelers I have worked on have the breather plumed into the intake like Buell's As for your trucks, are you sure that there isn't a filter in the elbow/canister where the breather tube comes out of the valve covers. I know all Cat engines have a filter there. The tube can be misleading as there will be some oil coming out and the canister doesn't look like a filter. In any event what are you saving, $5 on a 10,000 bike? Since 75%-85% of all failures are caused by some form of contamination, I think I'll run the filter. | ||

here's mine  | ||
| Andymnelson |
For these setups to work properly, the filter needs to be higher than the catch can- otherwise the filter and tube leading to it can fill with oil/gunk and not drain back into the can. | ||
| Gunut75 |
After I did my reroute, my exhaust STANKED. If the bike is in the shop, and I stand next to it while running, it's almost noxious! Burnz me eyez!  It's only while the bike is running the enrichment system on cold starts though! | ||
| Thrux181 |
Blacklightning, other than the filter and the hoses, what are the other parts you used in your set up? | ||
| Boney95 |
Andy, just as long as you have the elbow that connects to the catch can pointed upwards. All the gunk and water should only be able to enter the vent tube when the catch can is completely full, thus overflowing into the vent tube. | ||

Help! I just did re-route, used Ejiii's setup http://www.badweatherbikers.com/buell/messages/327 77/115730.html?1116461979 with the breather inside, under the airbox tucked in with the hoses (thanks!) - BUT - Now the bike skips and misses lots worse than the slight unevenness I had at low speeds before. I've taken it out on two smooth highway-type rides 1/2 hr. each so far, thinking it needed to adjust to good, fresh air only, but this didn't change anything - in fact, near the end of today's ride, coming back into town, I even got a little worried that it would just sputter to a stop... I must have messed up some other system. Any ideas? Sorry no pic's, until I tear her back open to fix. | ||

Tank Vent hose pinched? Crankcase hose pinched maybe? Check and make sure the stack (I think thats what that big black plastic funnel thingy is called) attached to the throttle body didnt come loose. Those are just a few ideas I can think of. |
