I fabbed up my own oil catch can yesterday. I think it looks pretty decent. It is held on with zip-ties right now, but I will be looking for a nicer clamp when I can.
It is. I threaded holes in for the barbed adapters, and the drain petcock, and used JB Weld on them to keep them in there. JB welded the end caps on too. I think it should hold up fine, time will tell.
Ok I have been looking for info about a catch can.Is that to stop from oiling your air filter? If so is there an after market one ? I just checked my air filter and there is some oil on the filter.have 32000 km on the bike
deal on catch cans is to channel the oil laden crankcase vapors out of air inlet. it seems to carbon up the throttle valve , intake valves, the iac and whatever else is in the path of this stuff. can is a place for crap to drop out of air flow and where you can put a rag under it to drain. you will be amazed as to how much condensation will drain out each week. that's the next deal is cleaning the hoses twice a year for maintenance. here in hi humidity the oil vapor will blend with water in air and virtually plug off the hoses in a yellow goo. I try to stay away from the s word guys. makes me shiver. anyway, for the first mod I did to mine, this was the best. it cleaned up the fueling tremendously and funny in that I'm running a uni filter that needs oiling now. Mine is homemade, blends in well and almost troublefree.
I'll continue my role as resident badweb defender of what I acknowledge is probably the wrong answer here.
I did the breather reroute on my M2. About 6 times. It moved the oily mist and smell to many different parts of my clothing, left a lot of marks on my garage, driveway, and parking places at work, and generally caused a lot of futzing and wasted time. On the XB's, there is also a speculation that some of the throttle body shaft failures may be aggravated by a lack of lubrication that the spooge could provide them when being sucked into the intake. So those are the reasons to just leave it as it left the factory.
The reasons for running a catch can are reasonable too. My Uly, at 30k miles, had significant carbon buildup when I pulled the heads. And Al Lighton (who I absolutely trust) says he can see the performance difference on the dyno from getting that hot oily air out of the intake.
I'll keep running mine into the intake, it's a simpler path to one of two imperfect results. Others choose the catch can, it is a less simple path to a possibly better result.
Plastic and heat usually does not end well. Don't worry about condensation. The outside air has plenty. Your motor swallows hundreds of gallons in a lifetime. Usually the vent line is under a vacuum. Any restriction puts a load on gaskets. Yes, it may run better, but there is a trade off. I agree with Reepicheep, it's not worth the messy smell....
I have a similar one on the 06 I just bought. It seems to leak a bit of oil when running high or sustained high Rpms. Enough oils to get on your pants/boots and a very small but noticeable drop in oil on the stick. Previous owner had the oil changed shortly before I bought it so perhaps the bike is seeking its natural level still... Anyone have experience with these?
I live in Minnesota, so it's getting to be cold riding now, and upon start up and initial running the Rpms will idle around 1100. But after riding for a bit, especially in cold weather, it will sometimes idle higher around 2000 Rpms...
Is this a fix that can be done with just the idle screw, or do I need to do a tps reset? Unsure if the breather/catch has anything to do with that, bike runs terrific, just trying to make sure it's tiptop.

jamfan, Has your "new" Uly done this since you've owned it? Probably needs TPS reset. Probably not related to breather/vent. For more input, on this, start a new thread.
I did the breather re-route on my last lightning and I plan to do it again on my Uly at some point. The only downside I see to it is the drops of oil in my garage. Otherwise it seems to run a bit better with the re-route
Reepicheep what about running a catch can ,instead of a vent on top you run it back into the air intake?That way you remove some of the oil and you wont have the stink of oil on your pants.
Question two, has anyone thought of making an adapter to drain the catch can oil back into the swingarm, like maybe through the dipstick hole? It is crankcase oil after all.
"Question two, has anyone thought of making an adapter to drain the catch can oil back into the swingarm, like maybe through the dipstick hole? It is crankcase oil after all."
would not advice to do so, with a healthy engine about 95% off the fluid in the catch can is condense from the hot air cooling in the hoses, not advisable to put water in your oil tank
I made mine with a fuel filter in line to stop dust and stuff that might get sucked back in and ran the outlet hose under the center of the swing arm to drip on the top rear of the muffler.
My theory is that when it is hot enough to vent off vapors, the muffler will be hot enough to evaporate it. And so far it does with no mess.
My suggestion for emptying the $plooge can is: Run plumbing from the dump valve into the muffler. Do not dump while engine is running. Just drain it into the muffler prior to taking a ride. The heat will cook it down and eliminate it without fouling the engine with it. You won't have to carry it to the trash can.
I don't know why people work so hard to put a filter on these things. It's impossible for anything to go into the engine with the PCVs and in evolution bikes, the umbrella valves. Air and vapor only come out. That's why I gave up on my X1 breather and just ran a tube to the exhaust outlet. The baby-snot goes out to the street and not to my right foot as it used to.
My X1 is on the second breather hose now since a dealership didn't know what to do with respect to routing it and it burned on the rear header. The only replacement hose I had in the garage was clear neoprene. It's actually fun to watch it condense out on a cold day and work its way down.
