That seems excessive to me. Is this better, the same or worse than after the conversion? I would get some longer hose and point it down by the Kickstand, but I would put a catch can at the end so you don't get oil mist over your rear brake and or/tire.... | ||

Since I converted to syn3, this solution is no longer working.  The oil mists right through the filter. I think I'm going back to the stock setup and run it back into the carb. | ||

JQ, pretty much the routing I took. I just left it slightly longer and curled it under the lower rail and tied it there(pointing out and away). Mine finally puked the other day whilst out flogging it on a cool day. | ||

Az - I tried the same setup as you. I even ran the filter up to the back of the tail section. It never quite dripping/misting. Finally ordered the XB rocker covers last weekend. | ||

I run my deal unfiltered. With the oil/gauze filters, it seemed every time the thing got wet it flung a mist of oil all over things. I think the other key is how you channel the flow of oil/gases/water. My setup has been flawless thus far...not even a drop has ever come out the breather tube, even though the "catch tube" always accumulates some nastiness. Az, try running a much longer hose to the filter (still pointing up), then "T" your catch tube directly down instead of across...basically flipping the "T" 90 degrees. That's what has worked for me. Keeping the catch tube longer helps too. Those XB rockers sure are stinkin' ugly! | ||

Rick, thanks for the suggestion. I never even considered lengthening the tubes. I'll give it a shot and see what happens. | ||

After trying bunches of stuff and having every pair of pants I own with a spot of Mobil 1 on them *somewhere*, I now just tee off the breathers, run a long piece of tubing around the *front* of the engine right around the back of the oil filter mount point, and all the way back through the shock mounting eye so it terminates back close to the exhaust outlet. With that long a line, I don't think not having a filter will hurt anything. The whole setup is more or less invisible on the bike, the drops stay off me. In theory a catastrophic failure could result in oiling down the rear tire, but if there is enough pressure to blow out that much oil out the breathers, it will probably blow out the crank seal and put tranny fluid all over the back tire anyway. I would either do that, or just route the stupid thing back into the carb again. Its a continual PITA to do anything else... | ||

I run 2 separate lines from the breathers, up along the frame, down to a catch "can" tie wrapped to the battery strap (M2). I'm currently using a clear Coke bottle, no filter, and the 16 oz. volume seems to let the gunk settle out without spraying anything. I've only got a few teaspoons out of the motor in 1500 miles. Everone asks about the Coke bottle, and "crankcase ventalation" seems to satisfy them. My buds laugh at it as I am a hardcore Coke drinker. edited by aesquire on October 30, 2003 | ||

My simple breather is a very large fuel filter (input and output side by side on the top) that I plumbed a drain into. Works pretty good, has it's own integral filter built into it, and it installs cleanly with only nywraps. After every ride I drain about a teaspoon of spooge out. | ||

Does anybody have an American Sport Bike catch can mounted to a tuber? I purchased one used on here but can't really figure where to mount it. Did you drill holes? Tony | ||
| Steveford |
I've mounted a couple on the rear fender by the license plate which does entail drilling holes in the huge, ugly hunk of plastic. If you run the line through a hole drilled through the fender, it'll make the installation look almost professional. | ||

Country, There is TONS of stuff here in the archive regarding the brather system in the Evo motors. In a nut shell, what Al said earlier is true regarding routing anything up. The Force, Devonator, etc. all route up. If you look at the way the umbrella valve in the head works there is no way for any spewage to go but out. When you route either or both breathers up, the spooge will collect and puddle at the lowest point(s). When enough preassure builds it blows it all out the breather hose leaving a big mess. The hot setup these days is to replace the upper and middle rocker box covers with units from the XB. Check out this link to see how it was done on my S2. My M2 is done the same way. The XB covers use a PCV valve out the top. I get very little dripage out of either bike unlike before the change over. http://www.badweatherbikers.com/buell/messages/47623/55910.html?1083251044 Good luck! Brad | ||

Bluz. After thinking about it for awhile, I know that I can take both breathers down with the same 'T' you used on your rockerbox replacement. That way everything will be going DOWN. I will have to figure out a way to locate the "filter" in an inconspicuous place, but that shouldn't be tooo hard. thanks again. | ||

I took bits and pieces from the existing stock hoses and fabbed a system that runs down all the way to a catch can mounted on the left side, underneath the tail section. I use a huge fuel filter as a catch can. I cut the top of the filter housing off and glued a small K&N oil breather on and drilled a drain hole in the bottom. The whole set-up costs less than $5, is totally hidden by the bodywork, and works great. It even looks stock because the white filter housing matches the white brake fluid reservoir on the opposite side. I'll post some pics soon... | ||

Socal, I mounted the American Sportbike catchcan on my 01 M-2 by using one of those rubber covered pinch clamps. I think its 5/8in from Lows, clamp it around tale section down tubes and put a 1/4-20 thru the clamp and the bracket on the can. | ||

Country, I did just what you are describing, and have goo on the right knee of every pair of pants I own to this day  Use the T, run it all downhill, and just get a long piece of tubing and route it around the front then bottom of the engine, all the way back to near the shock. I run it through the shock eye, and cable tied it there. Put a filter there if you want, but I don't think its necessary. That would even be a decent area to rig an invisible catch can. Yes, in theory, if you have some sort of massive engine failure of some sort, or way overfill the oil, it could burp onto your rear tire. But the same is true if your oil filter spins off (been there, done that) your primary crank seal fails (been there, done that) or your primary cover gasket fails (been there, done that). | ||
| Country |
Thanks Reepicheep, that will probably do the trick. I just couldn't visualize what needed to be done. | ||
| Socal |
Wman - that's not a bad idea. I'll give that a try. | ||

Here's something interesting from BUELListic.... he sent me the pics and I scanned them. This is what he was talking about for machining a mounting hole in the stock covers and then using the XB breathers. front head....  rear head....  | ||
| Buellistic |
BUELLers: Any questions about the XB breathers in the stock valve covers feel free to PING me for answers ljenne73c@verizon.net ... In BUELLing LaFayette | ||
| Bluelightning |
Buellistic, Did you leave the umbrella valve in you stock rocker boxes? Did you drill out the drain hole of left it stock? | ||
| Bluzm2 |
Blue, No need for the umbrella valve as you plug the external breather hole with a bolt instead of the hollow breather bolt. Same goes for the drain back hole. When you use XB covers, you don't even use the middle rocker box segment. Same results, just using old parts vs new XB covers. | ||
| Bluelightning |
So basically, you just drill a hole in the top of the stock cover, remove the umbrella valve, and plug the breather hole? Sounds easy enough, but does it work as well as the XB covers? I have seen Jose's S-3 with the XB heads and they work great. No oil/puke just a little water condensation. Much cleaner than my stock configuration. | ||
| Buellistic |
BUELLers: Have a 97S3T !!! Only Removed PN17597-97Y ROCKER COVER,outer... Drilled the proper size hole for a tight fit of PN17606-00Y GROMMET,pvc valve(and PVC VALVE)... Did not remove PN26856-89 VALVE,umbrealla as it will no longer work when you put a propper size bolt in head breather hole to hold PN29365-96Y SUPPORT,air cleaner(carb/air cleaner bracket)... You will have to remove a little off the bottom of each PN17607-00Y PVC VALVE so it will go all the way into the GROMMET... There is plenty of OIL/AIR seperator left on the PVC VALVE and it still will do its job... The oil drain hole modifcation was to help stop the oil pukeing out the OEM breathers... In fact someone made a KIT for this... "i" did this modifcation and was never pleased with it although it did HELP... The BLAST/XB PVC VALVE is the "FIX"!!! Could not see spending the "BIg $$$$" when my modifacation does the same thing!!! Cleaned the parts, put the PN17354-89 GASKET,rocker cover-upper and PN17358-84A GASKET, rocker cover-inner in the FREEZER for 2 hours, put together TORQUEing cover allen screws to THE PROPER TORQUE... An added thing "i" did after sealing with "YAMAHABON 04" was to use safty wire over the tops of the PVC VALVEs to make sure the YAMAHABON seal would hold better(less chance of weeping)... If you check the BLASTs and XBs you will find they do weep... Know there will be other "QUESTIONs" so feel free to ask??? In BUELLing LaFayette | ||

I have a 2000 M2 and I tried all kinds of things to deal with the breather issue and now I have it as taken care of as possible. Yes, I put the XB rocker boxes on the bike. I was happy to spend the cash because to the discerning Bueller, they see that and go "pretty cool". I have the hoses running all down hill and mounting to a Sel-Motion catch can that is mounted on the front exhaust bracket next to the voltage regulator. This set up works pretty good. I still get puke but much much less. Now it's mostly water. I was at American Sport Bike the other week and Al snapped some pic's of it. If I had a digital I would post it here. I am no expert but like I said, I have tried alot of different things on this bike and this works best for me. My advice is to do what you have to do to get those breather lines to run downhill. | ||
| Socal |
Lgpch, I'd like to see those pictures. Could you get Al to post them on here? Sounds like a nice set-up. Tony | ||
| Al_lighton |
Here's the one I took...  | ||
| Lgpch |
By the way, Al is one cool dude!!! He has been a big help to me with some paint issues I have had. I didn't even contact him and here is a with one of the pictures he took and he posted it for you. Al, I am in your debt for all the good advice you have given me. If you ever need specialized surf rescue services or a part milled or whatever. CALL ME!!!  Paul | ||
| Socal |
Thanks one cool dude Al! Lgpch - is that clear tubing running to the can? | ||

Hello again from China, guys. I just got my Buell ’98 Buell S1W White Lightning back running again. The return oil line grommet had detached from the oil tank, and oil was leaking profusely from this separated “L” fitting. After this happened I switched the lower drain line fitting with the upper fitting that had separated. This got the oil tank functional again. We put the bike back together & started it and the oil tank filler cap actually blew straight up into the air, (after starting the bike). So we then figured (myself & the local Harley shop), there was a problem in that the pressure was not venting in the oil system. So, I then ordered an oil tank (from American Sport Bikes). I also had them send me a set of four (4) braided steel brake lines. I had the local Harley shop install all this, but they have really limited experience with Buells. They were still concerned that there was a possible blocked oil vent that was causing this high pressure. Also, they said they have concerns about the oil pump. When they gave me the bike., the mechanic kept the American Sport Bike oil tank filler cap cracked open as to vent the oil pressure. What they said there was that the high pressure in the oil tank could have caused the oil line to separate from the oil tank in the first place. That this problem still may exist. In which case, I would expect that one of my braided steel oil lines may now blow off. Any of this sound familiar ? |
