Here's a home-made catch can made out of Tygon (F4040) tubing, K&N filter, 3/8" barb tee, 6 small clamps, 2 medium clamps, 3 zip-ties, and a spare bolt for the end plug:  I'll have to wait until spring to see if it works. | ||

Looks like it should work just fine. The tubing looks like it's full of antifreeze...nuclear green. | ||

So is this hooked up to one of the overflow tubes? Where is that little filter attached to? | ||

YIKES!  | ||

He hooked both of his crank case vents to the tube coming down. the filter is to allow pressure to vent after gravity catches the solids in the tube. Similar in intent to my norris performance catch can, but far less expensive. nice work. I can see doing somthing similar on the race bike. It seemed like a shame to add the weight of the catch can after we worked so hard to remove weight. Looks like you've done the re-engineering for us. Thanks Donutclub! | ||

I actually got the idea from my old RS125. It used a clear plastic tube for the rear brake reservoir. The tubing is actually yellow in color, it just looks green in the picture. The Tygon tubing is UV, ozone, fuel, and hydrocarbon resistant, hence it will stay flexible and not harden over time. The filter is attached to a 90° bend 3/8" hose. It's the hose that is removed from the rear PCV valve when installing the open air box kit. | ||

Looks kind of korny to me.  Is that the redneck version? My opinion, if you can spend ten grand on a bike you can spend a little more then 10 bucks on a catch can design. | ||

Im still trying to figure out why to the whole catch can thing? Engine oil is changed a 5k some prob at 3k and at tempature the water will vent right, so this is to solve a problem that really exists or just to add a trinket ? MDM | ||

It helps to catch small amounts of water that would otherwise go into the intake. | ||

...........the small amounts of water that would otherwise go into the intake......and burn off harmlessly?  | ||

The dyno tells the tale. Al at American Sport Bike has the dyno charts to prove the value of removing the crank case vents from the air box. Think about it, warm oily moist air is vented directly into your air box. Making you intake air moist, less dense, and oily. That's the main reason. A cleaner air box is just a side benefit, but no one will make you put one on. | ||

I have been running a catch can/ That set up for all last summer...and I can tell ya this ,that the junk that collects and goes out them vents I wd. NOT want it to go inside my motor...Its a EPA thing with all manufactures and they can`t let that go in the air so they burn it off inside the engine.... And its not just water by no means... And yo make it even simlier one does not neede a filter I just upsized the hose where you wd. put a filter and bend it around the shape say like a bananna ,as long as you keep the can/empty hose drained you need not worry...
