recently installed one of those polished catch can jobs from American Sportbike, it's mounted on the left side. All is well except I've noticed that some (fuel smelling) type mist is escaping from the element and getting on the fuel filter/lines/bike frame. Opened up the catch can and it was dry. Normal? Any way to prevent this? | ||

The vapor will always need to escape. If you could figure out a way to condense out the vapor, perhaps it would stay put in the catch can. Try to route the hose into the cold air in front instead of between the cylinders? Maybe a metal hose would help to cool it? I'm just throwing out ideas here. I gave up with filters, catch containers and all and just dumped it to the street in front of the rear tire. I hope you have better luck than me, though I gave up without much of a struggle since my catch can was home made. (empty drygas bottle) | ||

I kinda just figured that this was, and is, the case as it relates to the vapors getting out. Think I might try a small pot scrubber in the bottom of the catch-can. My theory is that as the vented particles enter the catch can they'll collect in the scrubber mesh & condense (at least somewhat) instead of being forced directly into the element and all over the bike. Maybe a pressure regulator would reduce the outflowing particle momentum as well? Too bad I never got into chemistry, otherwise I might know of some sort of bonding agent that I could add and aid in keeping the stuff from coming out the element. Since you routed yours out onto the ground, do you ever notice any build-up on your bike or tire? ever worry about puke affecting tire traction? | ||

"Think I might try a small pot scrubber in the bottom of the catch-can." Check out my $5 fabricated catch-can in the Breather section of the KV. It's at the very bottom of the thread. http://www.badweatherbikers.com/buell/messages/3842/128427.html?1116420688 It works great with no oil mist working it's way out at all. I've further improved the set-up by converting to XB rocker covers and PCV valves running to the catch-can. It eliminated the clumsy routing along the frame rails and cleaned up the right side pretty good. | ||

I'll second that. I put the XB rocker covers on my X1 and routed to a catch "bottle" in my case on the right side, next to the battery. There is more space on the right side next to the battery and the can fit there perfectly. See my profile photo & you can see it. The can/bottle I have doesn't look very nice, but works like a charm. The XB covers definitely make the routing of the lines much easier. If I made the hoses a little longer, I probably could have even hidden them better up tight under the tank. | ||

so the pot scrubber works, great! Someday I'll go with the xb covers for the sake of cosmetics. Currently tho my set-up doesn't look bad at all to me. Assuming I can cure the mist exiting the catch can it'll be good enough for me. For the record, I have my rear head vent attached via tube over the top of my forcewinder to the forward head vent, which then exits into a 2nd tube which is routed down below the forcewinder elbow, between the heads to the catch can on the other side. It looks really clean. The set-up results in a net downhill line of about one inch. But, the last portion of the tube connecting to the catch can between the heads ascends about an inch. I have pics, but just need to bring my camera to work so I can post it. will do soon enough if anyone is interested. | ||

I have the vents through banjo fittings at the heads. The hoses then go to a 90degree T that is tucked behind the frame tubes. I'll post a pic of the routing when I get home. As for the dribbling tube in front of the tire, it doesn't affect traction at all. Bear in mind that we're talking about a drop per five miles, you know? The DJ catchcan looks sweet and I bet it doesn't dribble at all with the scrubber. I might try another catchcan this summer. | ||

It doesn't dribble or mist at all. Seems like when I installed the XB rocker covers, spooge production went down and the constituents seem to be mostly water. | ||

I've got the billet catch can from American Sport Bike as well. I used to have it mounted between the cylinders on the left side, right behind the ignition switch. i didn't like the fact that it could block some cooling so I re-located it down in front of the engine and attached it to the front shock mount. So far its been working great! No mess and real easy to drain. Here's a pic of the catch can installed.  | ||

There's that damn bike again!! Boing  | ||

Buellfighter, You have a PM. Hodakaguy | ||

here's my set-up:     | ||

That's the cleanest, most compact installation I've seen yet. Very cool. | ||
| Buellgler |
Dj, thanks for the props. There's about 1/4 inch clearance between the catch can feed line and the head cooling fins. My first attempt wasn't so good, I cut my line barely short, about 1/2 in. shorter than what's on the bike now. The first line was tight against the intake manifold and forward head. Weird. In the flesh it looks almost factory what with the catch can mounting position and all. Your pot scrubber trick works great, all the juice stays outta sight which is what I want. Thought I was going to be able to claim credit for that idea, but hey, great minds think alike right? | ||
| Djkaplan |
I'm pretty sure I stole that idea from somewhere... | ||

here's another variation on home-brewed -- lil filter on the top is a model airplane engine air filter  | ||

for the filter element in mine i use a stainless steel pot scrubber called "chore boy" i think...heres the link to when i did the breather and catch can set up on my heads,, kinda fun.. food for thought.. look if you want.. use the archive link at the top of the page to get to the beginning of the post.. latter, aaomy http://www.badweatherbikers.com/buell/messages/47623/114374.html | ||
| Buellgler |
I bow to your skills Aaomy. Here I sit on the other side of the country thinking I'm cool for swapping my rocker gaskets and then shoved a few rubber tubes together. you on the other hand made that custom venting system. I still stress over puting in too much oil! Big props...bet your bike runs perfectly as well. (Message edited by buellgler on March 22, 2006) | ||

Buellgler Where did you get those banjo bolts? I would like to do the same setup on my bike. I can only find ones with one 3/8th nipples not two. Thanks Al | ||
| Buellgler |
I got it locally from a chopper shop. Dug it up in their random parts bin. But I'll be seeing them in a few days and will try to find a source for ya. | ||
| Raceautobody |
That would be great Al |
