Is it OK to route the transmission/primary overflow tube to the same catch can that the (combined) crankcase breather tubes go to? The two tubes would go into the can on opposite sides. It's a Jaz mini breather can that comes w/a filter on top. Seems like that would be enough to keep the pressures from "fighting each other". 2000 M2 | ||

I would use seprate cans why tranny can bad crank seal? | ||

The only concern I think there would be is the volume of the catch can itself - with both routed there you might want a little more room ... When (note - I didn't say 'if')that crank seal goes, a tiny catch will not hold the fluids that come pissing out of the trans vent - and will fill up and probably overflow the catch .. and depending on where you mount it- can make an even bigger mess than not routing it to a catch ... But I don't think it should be an issue, I actually plan to do it on my S1 since it does see time on the track every now and then .... | ||

I was going to do just that with the same catch can. I ended up getting a smaller can with only one inlet, so I just left the tranny vent alone. You shouldn't have a problem as long as you keep an eye on the fluid level. | ||

I am running both tranny and engine into the same catch can... sick of when the tranny puked, it puked on the back tire, and everything in the back... I have since replaced my crank seal, but, keep everything in the same catch can, now, for mess, and looks... Havent had a problem... Chase | ||

Curious where you are going to hang the Jaz catch can. Mine is mounted on left side behind the fairing lower on the front down tube. I have trouble with the filter getting saturated then dripping oil down the inside of the fairing. Thinking of moving the can back to the vertical tube on the left side. | ||

Is it OK to route the transmission/primary overflow tube to the same catch can that the (combined) crankcase breather tubes go to It's not,IMO. It is not a good idea because you have to restrict the lumen of the two crank case breathers by a 2-1 adapter and that is capable to constrain the free in and out breathing of the crank case.In other word:this may reduce power.}} Curious where you are going to hang the Jaz catch can. I added mine to the battery strap.  | ||

It's not necessary for the trans vent to have a catch can, all it does is let out air and whatever water that condenses inside (as vapor) when the transmission gets to operating temperature. If the crank seal goes and stuff does start coming out, a catch-can is just a bandaide until the seal gets fixed. I coud see a problem of spooge and water backflow into the transmission vent line, too. The outlet for the vent line is next to the starter. You'd have to mount the catch-can lower than the vent outlet to keep gravity from forcing the spooge/water mixture into the transmission, but you'd still have the pressure in the line going to the path of least resistance. Once the transmission has heated the air and vented the vapor, there is no positive pressure. And as it cools, it'll actually slowly start to suck air (and what ever else is in the line) back in. Routing both engine and transmission vent lines to the same catch-can doesn't seem worth the effort or potential trouble it might cause. | ||

But this is the way it comes from the factory, isn't it?! There are a lot of not so good things coming from the factory,isn't it? Like breaking oil pump drive gears,to lean carburation,transmission gears that can't withstand the Buell's power,oil dripping or breaking shocks,oiling crank seals,a 100% leaking cheap rocker box paper gaskets,breaking engine mounts,etc.etc. The list is almost endless. You only have to look how many recalls our tubers have had during their relatively short history. (Message edited by xldevil on August 25, 2007) | ||

"But this is the way it comes from the factory, isn't it?!" The stock two-into-one breather lines also point up instead of down, but their very short lengths and their outlet to a low pressure area makes the situation moot. A breather line vented to atmospheric pressure in a catch-can makes it a different situation, but... ...there really isn't a lot of flow from the breather lines, just a little over a long period. I think joining the lines from each head with a tee connection probably does hamper efficency when used with a catch-can, but the degradation isn't to a point where it would be a really bad idea. I've done it and I've had the rockers off a few times, and I didn't notice any spooge pools or anything unusual, but... ...a separate line from each head into the catch-can would be the most efficient way to do it, no doubt. The key in any case is to make the lines as short as possible and have them routed downward along their entire length. Using XB covers is the easiest way to do this, as Ralph and many others have done. As long as you do follow these simple rules, joining the lines should work fine. You're both right. | ||

And besides, the only one of those problems you listed that I had was the leaking shock. The other oil leaks? Hell... it's a Harley engine... I think complaining about oil leaks is like saying the fish isn't cooked enough in a sushi restaurant: you knew that coming in. Just as I got every oil leak fixed on my M2, now it's leaking from the base of the rear cylinder... groan. You forgot stator failure, btw. | ||

Daniel, I didn't have had most of the mentioned failures. I avoided them by changing those well known weak points in advance.Thanks to the BWB and B.O.R.G. What I did have was ....... a stator failure.  Ignoring that my bike's engine isn't leaking at all,I really love it for being an imperfect piece of iron in a more and more boring perfect world and for giving my the chance to work on it. I wouldn't change it for any other bike I know. P.S. I forgot the speed sensor, voltage regulator.....tbc. | ||

"I wouldn't change it for any other bike I know." 100% agreement, Ralph...  | ||

That's all? Damn you're lucky! | ||

Buells don't leak they mark their territory!   | ||
