How-To: Crank Case Breather Mod (with pics)

[driftingswiftly]

yeah, i guess i understand that, but I am kinda referring to how a lot of the tubes are run all the way to the back. why not just shorten it all up and make the collection however long you want? I'm not bashing, i am just about to do this and I would like to do it up short but don't want to be missing any reason for having it so long.

 

[bardo688]

uh noob ? (havent read the whole artical in a hurry)
What exactly does the breather mod do? get rid of the hiccup rocking in first gear?

 

[driftingswiftly]

yeah. I just did it and only used about 30" of hose. i just ran the tube down the inside of the air scoop. T'ed off the filter and continued the like about 6" form there. all near the front. Whats the deal with the filters tho? I feel like they will clog up fast...and will the wet be an issue?

bardo: Yeah, that wsa my main objective. low rpms are smoother so traffic, constant rev turns and wheelies are more predictable. I definitely notice a difference. Its nothing life changing, but it is for the better no doubt.

Drifting, did you close the end with a plug or soemthing. If so, you'll be draining fairly often.

I left mine open to drain on it's own while riding, so I ran mine all the way down and up and under the driver footpeg. Anyway, most run it down towards the bottom end for draining convenience I guess.

Mine is open right now but just bc they were out of pet-cocks. I am planning on plugging it, and have 6' for collecting...will it really fill up that fast? I am hoping to only have to drain it like every 250 miles or so.

I noticed absolutely NO difference in the way my XB runs after this mod. None what so ever, but it does drain a clear fluid out every couple hundred miles.

Thanks for the DYI instructions... followed the instructions for the re-routing and then used a catchcan + breather setup...

No difference felt during riding, but 20miles were enough to collect 2-3ml of clear liquid...

 

[driftingswiftly]

So i did the mod the other day, I do notice a bit of a difference...but I have experienced a drawback too. it might be just me, but you know how everyonce in a while when you rev it from straight idle (like at a light or maube after you first start it) and you happen to catch it at the wrong point in the cycle and it spits and boggs down bit. Well it has never stalled before when that happened, but it stalled once since the mod. I don't think its a huge deal, but any ideas? I would feel like such a tool if I reved while makin eyes at a girl at a light and my baby sputtered out under me. haha

 

[bardo688]

can you do this on an 03 xb9s

 

[Stevenc150]

All years, any Buell. [up]

Okay; somebody posted a link to a vid of draining the fluid out of one of these compressor filters. I can't find it again. Anybody able to direct me?

Also, how do you secure the reservoir to the bike?

 

[Stevenc150]

I'm assuming you're talking about a catchcan when you say reservoir - it depends on the reservoir and you're mounting location. Below is the vid:

Wavex
where did you get that catch can from?Its really cool

 

[Baal]

First, thanks for the vid link. I'd seen that one, but I'd also seen a clip of someone unscrewing and dumping the liquid out of the reservoir on the compressor filter used as a catchcan, like in wavex's picture. I'm trying to figure out how to secure/mount one like that.

Wavex and I have the same thing, its an air/oil seperator for air tools. You can get them at the hardware store for about $5.

But how do you attach it to the frame?

 

[Enforcer36]

ok so ijust did mine. i wanna know what you guys think about where i put my collector. do you think i will have any problems with it being close to the oil cooler.

this is my set up

installed

from the back side of the oil cooler

let me know what you guys think. thanks

 

[driftingswiftly]

nice, thats exactly what i did with mine except i just have a short section of hose for my catch. I really like having it out front.

 

[Enforcer36]

quick question, do i keep the filter that is inside the seperator

 

[Stevenc150]

No need to, it'll just clog up eventually. As long as you keep it drained so it doesn't overflow into the red filter, you should be golden.
