Hello This is my breather mod on my XB12Ss.

I'm not using my airfitler box, so i made a hole in the bottomplate. The both tubes stick 1 inch in the pvc pipe, so the oily stuff can't go back in the tubes.

think i'm gona need to do this mode...

my airbox was full of oil...

 

[short lived x]

quesion.... i went to do the breather mod, and i found dried oil on top of the motor, any ideas?

 

[nativeXb12Rbuell]

I had the same problem short lived X .
Mine was caused by a leak that was from where the hose ataches to rear PCV valve with the plastic zip tie , it was very lose causing the oil mist to get blown out all over the rocker box cover . what a mess (like in your pic).


see here about half way down the page, discription and pics of it & my breather mod,
and I used steel hose clamps to keep it from leaking in the future

i have this problem also, still haven't got round to installing breather re-route so just clean up all the oil every could weeks.

this is the catch can that im using for the breather reroute. soon to be doing the air box delete.

Just did the breather mod, had a lot of fun putting it together, but after riding it around I wasn't really able to tell the difference.

 

[nativeXb12Rbuell]

looks good and pretty , I like the catch can alot.
(I used the same fuel filter for catch can and painted it black with see thru Buell letters see my profile for pics or back on page 9 of this thread)

only thing is the Brass and copper wont stay pretty for very long.[up]


does it still stutter or something?? What??

 

[Loki]

Mine stills stutters but not as much. :\

 

[fbfrider]

I rode around for a while today and had a good bit of moisture in there; mostly clear h2o, no oil. I like the bling bling, its a real eye catcher. Thanks for the props nativexb12rbuell, there's nothing that Simple Green can't handle. Still haven't noticed much difference in the bike; for some reason the throttle body seems like it sounds louder. Anyone else notice that?

Here is my wacky breather thing thing.

Its a Moroso breather for a car or truck chopped in half and re-welded.

 

[Loki]

Isnt that alittle ummm.... Big? Your bike doesnt puke, it just drips.

 

[Jobe Zeebuh]

^^^The good thing is if I forget to empty it once and a while its ok. Also, the filter will last forever and never get clogged. Plus to me it look kinda cool and unique. I think those small filters look silly.

09Buellxb12. Nice stealth catch can! Thats craftsmanship and ingenuity right there. Did you make that or is it a part off something?

Finally got around to mod the breathers:

Took an hour, cost $25 or so, siliconed all the fittings, looped off the airbox holes, re-routed trans breather tube down by swingarm,,,

but after riding it around I wasn't really able to tell the difference.

Thats good! If your bike is properly maintained you shouldn't see much of a difference at all.

If your bike is properly maintained you shouldn't see much of a difference at all.

Not true unless you think everyone that noticed a difference isn't doing proper maint. I for one, am relentless about proper maint. on mine and noticed a reduction in airbox coughs & low RPM stutters. Proper Maint. no doubt has some weight, but there's much more to it than that; including where you live, climate, seasonal, mapping, etc.

Edit: 07Bolt, you'll probably end up with drippage on the swingarm - nothing you can't wipe off though. I routed mine longer and zip tied under the footpeg - almost no drippage on swingarm.

some of the runoff would contain oil residue so you wouldn't want to get any on your tyre...

would be best to have a canister to collect the gunk.
