Obviously not a high demand for the part, or it is not cost effective for NRHS to market the butane lighter - barf bucket thingie-ma-bobber.

I want you guys to make one of these that is affordable and easily installed. All the work you do and you don't have this. I am miffed. How many housands of posts are necessary before you guys figure out that you can make some money with a product that is both functional and keeps our beloved bikes clean. I want it for 60 bucks and not 100. http://i21.ebayimg.com/04/i/07/96/c5/d8_1.JPG

This is similar to the M20 air oil Separator for aircraft, it is fed from the crankcase vent and has two output lines, one for air & water and the other feeds into the low pressure oil return line to return oil to the crankcase. This design is not a catch can but a return mechanism, so nothing to drain or empty (they are very slick).

It let me run the full 8 qts of oil in a lycoming engine rather than the 6 qts that you usually have to run. (Lycs blow out the top two qts without an air oil separator). I would certainly spring for one on my bike.

http://www.m-20turbos.com/breather.htm

The M20 product is priced for the aviation market (makes Harley look like pikers) and is too large to comfortably mount on a bike, but a snazzy (like that word?) aftermarket unit would be great...

Here is a cutaway of the M20...

OK... forgive me for being mechanically uneducated, but I truly do not understand what this device is...

Is this some sort of fuel filter to the carb, or something from the petcock?

Is this an oil catcher from a breather kit to catch the oil blow-by?

I have the oil that drips from my breather setup onto my garage floor, but I simply put a section of the Sunday newspaper on the floor every week... so what's the big deal?

added benefit of using these is that they breather very freely unlike some of the other breathers on the market. can prevent seal blowouts. and leaks.

Now THAT could be made cheaply, sold for well under $60, doesn't look bad, no moving parts to break, and solves the drippage problem.

Confused89

22nd October 2006, 03:34

It might just be me but I have several questions about how exactly this device works. Lets start from the begining.
Device is used as a "catch can" for oil that comes out of the breather ports on the heads. Excess oil flows into device through fitting on top. The filter is there for what? Does it return oil to the engine? If so how does it do it? And if it does how exactly can it do it if it has a vent aka the filter on the top of it. You said you have to drain it every so often. That means all of the oil does not return to the engine. I have a very good grasp on fluid power and how it works but as of right now I can not see how it can return the oil to the engine if it has a vent on it unless it is mounted at a higher elevation that the breather ports. Someone please explain all of this to me.

lagerdrinker

22nd October 2006, 03:41

confused, oil doesnt return to engine. it just holds the vapors and breathes through the filter.

DustyJacket

22nd October 2006, 03:46

The oil sits in the catch can. The filter makes sure the air vented to the atmosphere has no oil in it.

Joe Dirt

22nd October 2006, 13:59

It works great! The breather filter is from the import tuner section of Autozone, and is $10. The cap on the bottom is a heater by-pass cap. The "T" and the fitting on the bottom are from the hardware store. Using a collection hose instead of a catch can has a few advantages. The hose could be zip-tied to a frame tube or something, and you can vary the size and length depending on the volume you need. It can be run to a very easy place to drain it from. The hoses support the "T" fitting and breather, so there is no need for any mounting brackets. You just have to remember to drain it before the hose fills up to the breather. ;)

Not ALL.

The HurricanFlow from NRHSperformance does not, as well as some others. That is why you have to get a carb support bracket.

The H-D aircleaners do, though.

Well, yeah... I guess that was my assumption... don't you have to order the bracket seperate, or like does the Hurricane come with that ready to install in the kit? I figured without a seperate breather kit, all ac units using the stock H-D bolts would route the oil vapors back into the carb.

Obviously I don't know for sure, as the only personal experience I have is with the stock ac and my current Ness BS.

Always more for me to learn... :o

I can only answer for the HurricaneFlow A/C - you have to buy the carb bracket and some sort of breather. The sell an install kit with both or you can buy ala' carte. (The web site mentions it doesn't install w/the breather bolts)

Other A/Cs will be different one way or another......

Run the lines from the heads UP to a breather/filter. That way all the oil residue runs back down into the heads, not on the ground or below the engine where it needs collected.

Problem solved. End of thread.

And you may not want that going back into your oil supply. Breather catch cans collect a bit of watery, foamy goop, an oil/water emulsion from condensation in the breather offgas. Not a good lubricant.
If it was to drain back in almost immediately, would it be so bad? Most of the goop you see is a result of the oil sitting in your filter thingy for a few weeks, isn't it?

the mist/vapors contain alot of blowby. unburnt fuel, byproducts of combustion...
an enigine filled properly and in good condition wont have much loss. the only things that this device does differently is it keeps oil mist out of intake and off floor. youd be losing that oil anyway. just top oil between changes.

gwcrim

23rd October 2006, 17:15

Yeah, but it's just the same oil that's in your engine. No worse or better. Just in vapor form.

Keeping it out of the intake is the first priority. That stuff gums up the exhaust valves and pits the seats. Keeping it off the floor/bike is second. No need to spend $$$$. I just figured if you could let it drain back into the heads, you'd have the perfect solution.

Or have I been smoking too much crack?

nah, what you are saying makes sence. but the vapor form is directly the exhaust blowby and carries the most contaminants. why not just vent it out and remove it from engine? oil isnt like water where it will boil and steam, its very stable and has higher boiling point. the vapors are carrying the crap out of the engine if you let them.

23rd October 2006, 20:31

I like Ralphs idea of the clear hose. I might have to put one on there!:) As for the misted/blow-by oil, I'd rather not have it drain back into the engine. It isn't that much oil. It looks like a bunch when it is on the floor or the side of a bike, but it is a tiny percentage of the total volume. And, if you put a breather up high so it can drain back, you run the risk of water getting in also.;)

problem, not quite. every engine needs to breathe, if they didnt youd blow seals out all the time. running it into carb makes sence cause your lubing the top rings and cylinder wall. plus can use the breathers like the carb jets, certain situations can cause negative pressure in engine further help seals. think of a car, pcv valve in valve cover and hose goes directly into manifold. people remove the pcv and install valve cover breather and all of a sudden they blow out rear main seal...thinking specifically the mustang 5.0
chuck brought up point of keeping correct level, do that and no problem or at least minimized. correct level is middle of dipstick, not fully topped.

Take a short air cylinder like a Bimba, 3/4" piston two inch travel. remove the piston/rod and end cap. Drill out the hole in the end cap (where the rod used to stick out and thread it for 1/8"NPT. Next plumb the vent hose into the fitting at the rod end of the cylinder.(This will be the top when mounted) Thread a brass plug into the other end mount it vertically on the frame rail. screw the end cap back on and install the breather in the end cap(now the top cap!!). WALLAH !!

I've had one of these filter-topped catch cans with the drain on the bottom for about 6 months. Drain it a few times a week just out of curiosity. What I usually get is a vanilla pudding looking oil/water emulsion + a little water. It's as thick as pudding, and I usually have help it out with a small piece of wire. If I really want to get it clean, that filter on the top unscrews and some parts cleaner shot through the filter hole does the trick.
Those with the breather that goes up rather than down, must have breather lines full of this oil pudding stuff. Down and down only would seem the better idea.
My oil level is right at 1/2 way on the dip shtick. I've been thinking about taking some out just to see if there's less vented, but havn't gotten to that yet. It does seem to spooge more at high rpm, less with cruising.
I mounted it to the forward control spot on my mid-control bike. Not sure where you forward control guys would put it.
I like doing my little part to help the environment, and also knowing that when I'm cranking the throttle, oil is not spitting out to lube my back tire. Yes, I know, get some oil out of that tank. I'm gonna get to that soon.....:coffee

MakuaKane

29th December 2006, 08:24

I took off the catch-can a few days ago. Got tired of draining it. All those little tiny emulsified oil particles forming together to make a yellow fluffy sludge, then if I didn't make sure it was drained out, the sludge would make it's way up to the filter, then I'd be having a little residue on the bike just after the filter.
Initially I did it for the environment, but I realized that if I'm gonna get serious about that, I'd trade in the 65 or so horses for one real horse.
So now I've got the breather lines routed down. Never a drop of oil under the bike. Seems like a better way than slowing the airborne particles down enough for them to form sludge.

Just another harley aftermarket gimmick whose main function is to drain our wallets if you ask me . A hose works just fine for me .

Exactly. Buyer beware. I wasted my money so you won't have too. That's why I wanted to post the follow up, in case someone was looking for this little gimmick.

Just got an idea! (Did you feel the earth shake?)

Run the lines from the heads UP to a breather/filter. That way all the oil residue runs back down into the heads, not on the ground or below the engine where it needs collected.

Problem solved. End of thread.
Except it doesn't, because there're one way valves stopping it.

How does the horseshoe breather bolt by-pass from NRHS work then? It would seem to me the gas from the front cylinder would go up over the horseshoe then down, leaving oil residue at the banjo eventually pugging up the hole. The rear cylinder would drain both oil and gas thru the tube.

BTW, mine is vented down in front of the secondary belt pulley. there are 2 other hoses there already, I just zipped tied to them. Dan assured me I wouldn't be lubing my rear tire and I've yet to be able to feel anything at the tube end.

It's an alternative to having separate hoses from each breather bolt; the idea is that all the crankcase breather gasses, blowby, etc from one cylinder goes over the horseshoe and down, joins with the stuff from the other cylinder, and goes out the hose, to the catch can, or wherever it's routed. None of it goes back into the heads, unless the umbrella valves have failed.

Some folks think that having to have the stuff from one cylinder get pushed over the horseshoe isn't a good idea, that it'll restrict the flow, and prefer two separate hoses. It seems to work though.

This has been interesting. Made me go out and use the parts I bought awhile back. I like it..... Got the different bolts, and the black rubber thingies from Zanotti's

H-D can't vent the crank case to the atmosphere as the EPA will not allow it. Cars have had positive (negative pressure) crank case ventilation for years and this is sort of like that but not exactly. I wonder if the stock restrictive air cleaner provides for more negative pressure to the crank vents than a low restriction (K&N, etc.) air cleaner does and that's why bikes with stock A/Cs don't have as many problems with oil coming out of the A/C as more of it is being sucked out of the vents and into the intake. I'm no engineer, but I'd bet that a fresh and unloaded K&N filter allows for more dust damage than any damage that could be done by normal blow by gasses being sucked back in to the intake.
