Last summer when I first installed my catch can I would open the drain valve every time I filled the tank and would typically get 3 or 4 drops of water. Then fall came and the weather changed. Now I can get a tablespoon of water after riding only 50 miles and by the time I've gone through a tank of gas the catch can is so gooped up inside it won't drain at all. It's getting to be a real pain having to remove the cover and clean it out after every tank. I've even tried just leaving the valve open all the time and it doesn't make any difference. This picture is after only 140 miles.  | ||

Looks like a lot of condensation in your oil. Take it out for a long distance ride where the engine can get hot and stay hot for an extended period of time. That should get all the water out of your oil. btw that white goop in your picture is what happens when water and oil combine. Don't worry - it's normal. Every time the engine is run and then shut off, water condenses in the oil as it cools. | ||

Use a different catch can,  | ||

thats what it looks like when it cools rapidly no worries its just water and oil mixing from condensation. Your primary can do that as well especially if you powerwash it alot. | ||

good reason to put the stock breather back; that's what it's for. | ||

that's why i use a air compressor type catch can...see through, toolless drainage. and not spewing that crap back into my engine. mine also fills very quickly, btw. | ||

Hey Gary - mine does the same thing, but not that often. Usually a couple of cleanouts throughout the riding season (3-4 months). Mine doesn't get as bad as your photos until 400-500 miles. I'd try some of the tips listed in the above posts as see if that helps. Peace of mind knowing some of that crap isn't being ingested by the engine. | ||

I am very familiar with what happens when water and oil mix. I just don't understand why there is so much after so little time. A couple weeks ago I went on a 200 mile ride with Growl. I cleaned it out before we left. Most of the time was spent at 70+ mph. When I got home I opened it up again. It was probably twice as full as the above picture. I'm leaning towards just eliminating the can and running an open hose out the bottom. Isn't that what the factory did in the old days? | ||

That's why I don't open those things up. BTW, isn't that foam generated after the venting and not in the engine? If so, it's not a problem. If I found that in oil I was draining, I'd be panicking. | ||

Definitely something of a PITA, but on the other hand, if you didn't have the catch can, that stuff would be going into the engine. And thanks for the heads-up. I have the same setup on mine, so now I know. | ||

climate can also have alot to do with it and location of the can the faster the vapor cools the more condensation you will get I believe. | ||

PS if you are gonna just run a line out put an old school pcv valve on it so it doesn't go compressor on ya and don't vent that in front of a tire  | ||

I have a home made catch can and have never seen anything like that, but a friends Ducati had similar issues, he changed oil brands and that helped. Better solution is to go for longer rides and get that oil temp up their for a while so that the moisture can evaporate. If it was my bike, I would do an oil change. That may be overkill, but I would feel better. | ||

but a friends Ducati has similar issues, he changed oil brands and that helped What kind of oil are you using? If someone else has the same gooping and runs the same brand oil, ... ? Info could help to see it some brands are more susceptible to gooping ... | ||

"PS if you are gonna just run a line out put an old school pcv valve on it so it doesn't go compressor on ya" Brumbear, what do you mean by that? | ||

}I just don't understand why there is so much after so little time. Did you over fill on your last oil change? | ||
| Garyz28 |
Oil is HD synthetic. Filled about half way up into the x's on the dipstick. btw, winter is when we get our highest humidity here in California. I suspect that does have something to do with it. | ||

I'm too cheap to buy a trick cast catch can, which I consider to be superfluous. So, I just ran the hose down to the bottom of the chin fairing and let spooge drop where it may. Road Draft Tubes were used for years (cars and motorcycles) without any adverse affect to vehicle operation. Pollution... now that's another story. | ||

when a motor starts some times it will suck air in faster than pump it out the pcv stops that I had to do it on my old 45CI flat head but I really don't know if would apply to a modern engine. I was just fooling around mostly |
