I thought this looks pretty good. Is it Ok to have it exposed like this The ones I have seen are all tucked behind the oil cooler mount  | ||

Oops , I talking about the breather filter. | ||

Here is a pic of Zoedogg's. You'll be good. Hope you don't mind Zoe.  | ||

I would think you would not want to have a positive pressure on your vent. Where it is sitting it could have the opposite of the intended effect of venting crank case pressure. | ||

So for the uninformed in the room -- me -- what is the point of that attachment and why would changing the angle change it's function? Is this a retrofit/upgrade to an existing mechanism or an aftermarket add-on like a RSS or the like that can improve the function of an XB? Also, if it is venting pressure from the crank case does it drip oil or need cleaning? I've seen them before but never really knew what they were for. Oh, and how difficult is the install and who makes/sells the parts. Thanks! | ||

dynamicpress I think diablo is concerned with incoming air potentially pressurizing that hose and not allowing ventilation. This could very well be possible. easy fix is to run the hose to the other side of the can and FWIW mine is vented below the catch can. the filter just keeps it from sucking stuff back in to the can. Retrition: kinda surprised you dont know with all your other comments.... haha, seriously, you do have some comments. This is a common "harley" mod to reroute crankcase gases out of the intake tract and to atmosphere. The catch can part collects all the gooo and moisture that would normally go through your throttle body and allows you to collect it and then drain it when you want. Not sure if this really does anything AT ALL (read horse power, reliability) but its common when you have an open air box | ||

Yeah, I get the raw mechanics of the thing but I wasn't sure if there was a benefit, a concrete one that is, or if it was more of a preference/simplifying thing -- is it like putting on steel braided brake lines or is it more of a line re-route to lessen binding. Both are worthwhile but one is more a refinement of the existing setup. I'm pretty knowledgeable about metrics and things with 4 wheels but I only have a year or so with this Harley V-twin engine and Buell design -- wish I would have found these brilliant bikes sooner, I'm in love. Thanks for explaining Tbowdre, I think I'll be putting that mod on the back burner since open airboxes and Washington State don't mix so well. Thanks a bunch!

It prevents coaking on the throttle body that results in a sticky throttle. Thats why I did my catch can mod. | ||

After seeing some of the crap that has come out of my catch can I don't know how anyone would want that crap going into their bike's intake. BTW you can make a catch can out of a couple of brass or plastic hose fittings and a filter for the vent. do a search for budget catch can and several variations on the theme should come up. There is no reason to delay. Oh yeah, Al at American Sport Bike did a test some years back that showed 1-2rwhp gains from adding a catch can. | ||

Hook us up with a link if you would Diablo...I didn't find anything useful. | ||

how difficult is the install? sounds like a worthwhile thing to do maybe. | ||

I'd say 30min to those who havn't done it before. It's easy. Todd the XB breather system doesn't have a suction to the catch can or at all, they use a one way volve on both rocker covers. I also don't use a filter on my catch can vent, no real reason other than I didn't want to pay for one. (Message edited by WantXbr on May 27, 2008) | ||

catch can install instructions. http://www.kdfab.com/catch%20can%20instructions.ht m Note Line #3: You don't need to disconnect the servo motor just simply remove it with the foam and set it on the area where your seat is supposed to be. Note #11:If you don't have the plastic plugs you can use 1/2 inch long 3/8" piece of hose instead. Just put the small piece of hose in the airbox base and then insert a bolt into the middle of the hose. Make sure its a tight fit use sealer if you'd like but be sure you install the bolt from the bottom of the base so incase the bolt does come out in will fall down to the motor and not through your intake. | ||

Anyone else want to advise me on my placement of the filter ?  | ||
| Diablobrian |
A lot of this has been covered many times before on threads like this one: http://www.badweatherbikers.com/buell/messages/327 77/217555.html where I posted a nice pic of a super cheap catch can, hp gains, placement of cans, and to a lesser extent filters, reason for filters etc. Hope it helps. I did a search for "catch can cheap" | ||

sry to be such a du-mass, but what does that do? **i have not read the thread yet, just saw pics, so if its aready been said here, my bad (Message edited by ochoa0042 on May 28, 2008) | ||

From what I've read... For emissions reasons, the oily watery vapor gunk that comes off of the cylinder heads "crankcase gasses" is rerouted back into your air intake. This 'cruddy' vapor mixing with your clean intake air has been linked to low RPM stumbling and gunking up the throttle body - all for the sake of cleaner emissions. This mod reroutes the breather lines from your air intake and into a user mounted catch can (an in-line breather/air filter is usually mounted too). The amount of splooge collected depends on your climate and riding style, but just periodically drain the catch can and be delighted that this stuff is no longer going into your engine's air intake! | ||

Umm if anyone thinks this is wrong or I might be messing something up PLEASE tell me but here it is I have NO catch can just re-routed breathers to filter was planning to get catch can but when i didn't see anything coming out of the filter I just thought it would be ok as is .... comments ,concerns,something .....please!  | ||

may be not a big deal at all.. if ya dont mind spooooooooge all over the front of your bike. other wise it will show up. yes it will show up... moisture, oil, sludge, byproducts of combustion, heat, breakdown products of oil and and and a catch can is nice to collect it all and drain when ever you feel like it- while fueling up, sitting in the garage, parking lot at work. |
