Re-route hoses

[The Tin Man]

I think the mod is great too but fuel mileage suffers a bit. I didn't use the filter and see no need too. I get very little coming out the end of the hose. Don't get me wrong, there is a little bit coming out but not enough to make my rear tire slick or anything. As a matter of fact I had mine drain right above the exhaust outlet on the muffler and when I ride the drops get blown to side of the bike.

ulyscol, thats a really good idea for the catch can that your thinking about making. Have you been able to get one made yet. If so let me know, I am interested if would like to build a extra one

I have still been thinking about doing this and have the bike somewhat apart so I figured i'd give it a shot.

After seeing what si going on and looking at poppinsexZ's pic in my opinion you can't block off the end of the hose. This is the PCV system. You can re-route it and risk getting less vacum and proably be ok but you have to have some crankcase breathing on the engine. It can not be a closed sytstem.

Here is the Catch can on the front of the oil cooler bracket

Here is the Breather.

You must have a way for air to get in and out. I would recomend at least a breather at the end of your hose.

I know its minimal and doesnt really matter, but like the tin man said above and out of curiosity, what kind of drop in MPG are you guys experiencing??

 

[poppinsexz]

Was averaging 53mpg.
Swapped to the race ecm, race muffler, K&N, and the breather mod, my only fill ups since then and I have gone to 48, and 50mpg.
Not enough to really quantify yet, could be just riding style and weather.

Nice setup poppin. That is one of the nicer ones I've seen. by the way the reason I referenceed your original pic is becuase you can clearly see the valve covers in that picture and the breathers comming off of them.

by the way. Where did you get that catch can?

 

[poppinsexz]

I got it from AmericanSportBike.com, it was a little pricey, I started to make my own but it's for the Buell so WTH. Much nicer than I would have come up with anyway.

I had understood what you were doing, I just added the pictures to show all of what I had done. I had wanted to post pictures of the can and breather when I posted the hoses the other night, however I didn't have any.

This little thread really took off...almost as much interest as the exhaust threads.

Yep, I figured we needed a starting point and people keep making it better [up]

**Buellxb needs to make stickys **

So I pulled mine apart and began doing this mod. The pics don't do justice to pliing it apart and seeing it for yourself.

My response to a few things aforementioned. PCV is not an issue here. The way it is setup is not like a car. The hoses vent the crankcase gase to the airbox where IMO there isn't enough vacum to say the hoses are under any vacum worth mentioning. Venting it elsewhere should cause any issue.

2nd there is a lot of oil that these things spew around in there. I'm really looking forward to driving it with my engine getting air and fuel (and nothing else.

Now some questions.

Do you guys think that it is worth opening up the upper airbox lid? YOu would get more air but you loose the ram air effect from mthe stock setup. Do you guys see the factory setup as a restriction? I wish we had some math wizzes to calculate the max CFM the engine can breath and the amount that can flow through that frame port.

Of course its worth doing, the factory "ram air" isnt really ram air at all. With the airbox the way it is, the air gets deflected all over inside the box, not really being "forced" in. Opening up the airbow will give you less restriction, although it wont do much except make your bike run lean without getting a proper tune. Once you mod the intake and exhaust...a tune is a must to get the benefits of your modding.

I have the race ECU and the micron pipe

 

[climberfreak]

so is this mod suppose to increase popping? lol cause damn hopefully it will clean up the more i ride it

 

[Trill]

I did this mod and drained my tube today and alot of water came out [up]

Glad this isnt going into my airbox

 

[mrdozer2you]

Go for it then [up] It should be ok...but will be better with a tune.

just performed this mod today. kind of a buell noob but i know myway around a tool box. it was an easy job to do but i really almost had adverse affects. my 12 bolt is running a little better but it also died a few times while at an idle waiting at a light.I didn't really see abything in previous posts but is this something that deserves a tps reset?

 

[Stevenc150]

....is this something that deserves a tps reset?

Nope. You did nothing more than make the air you're intake sucks in a little cleaner and keep from having oil splatter in your airbox.

I followed the directions and was happy with the results. Seems much smoother now, open airbox is next. Hope warranty isn't too sticky....
