Breather Reroute

Buellxb Forum

Help Support Buellxb Forum:

on my 2007 XB9R city X with 525 miles on it, i did the reroute and hayden breather valve set-up. i don't think it made a damn bit of difference but it sure gave me a good excuse to spend money. also gives me parking lot bragging rights as to who knows the most about buells, sexy parts hanging on bike, crankcase scavenging dynamics, on and on. LOL LOL:D
 
I did it to get rid of a lot of the residue the stock set up left on the inside of the airbox, when I got the bike a year ago. But it did seem to clear up a lot of the jerk/surge/stumble I had when I held the throttle steady at a low rpm...like when I was practicing the Box exercise from the basic rider course.
 
I am thinking I may need to do it. I went for a 100 mile ride today and everytime I would get on it at about 3500-4000rpm it would lag a bit before kicking in. Anyone use the KDFab set up

Pwrhse, did you get the hose's from there also? and air you running a small filter?
 
Thanks captain. You wer spitting a lot of oil before. I am actually found an old spray gun, that is beyond repair. Thinking about converting the canister to a catch can.
 
I got the open air kit and the catch can from American sport bike at the same time , and if I remember correct the hoses came with air kit , not the catch can . I do not run any filter , do not need it with the can , it has a an overflow that works as a vent . My bike is an 09 and I do get a little build - up after some rides . I usually check it after a few rides and the build - up is there , just not much .
 
my bike had a pretty good oil film in the air box and a lil on the air filter. I'm perdy sure its not from "excessive" blow by its only got 6.7k on it. I ride in fairly humid weather (southwest iowa southeast neb in the spring thru fall. So to avoid ne Crankcase gasses/oil goin down the intake i went ahead with it, spent 50 bucks. Dont know if it will make ne difference havent rode it yet. I figured what the hell, it couldnt hurt. Also all the harley custom intakes or Screamin Eagle intakes route the breather away from the intake charge so there might b something to it.
 
Thanks for the input guys, I am looking into a couple different catch cans right now. I will post pics onc I get it done.
 
Well this is my attempt at what I thought would look good. Opened her up and fixed it. Ran the line down in behind the oil cooler and put a T in behind there. One line runs straight down to where I have plugged it with a brass cap to drain manually and the other end has the filter on it. Clean and neat in my books. Thanks to everyone for all the posts and pictures and information, made this a lot easier. Cost me around $20.

Can you do a breather reroute and just route an open hose draining to the ground? I am wondering, since the engine breathers both suck and blow, would you be risking sucking in dirty air into the engine?
 
Yes, But your engine Blows is why you have oil in your breather base, as your engine gets more wear it get worse, A ground hose would drip could get on rear rubber bad thing. Thats why they call it (Blow by) not (Suck in ).:black_eyed: Also each rocker cover has a PVC valve,

I've had an open hose behind the left footpeg that just dumps to the ground for years (almost 30k miles). Every once and a while I'll get a tiny spot of spooge on the ground after a ride when its parked. Its mostly water vapor that condenses in the hose and mixes with a little oil residue so it always looks milky. You dont get anywhere near enough blowby while riding to affect tire performance.
