So I am attempting to find a no maintanance solution to the infamous oil blowby issue. I have tried multiple solutions over the past 12 years. 1. Currently I have a forcewinder intake and then run a blowby tube down to the ground. Unfortuantely, it is messy and I am not crazy about oil landing on my rear tire. 2. I know that the stock version just ran it into the air cleaner, but the way that worked it would pool and drip, and that was annoying. 3. I had a catch can under the tail section but I would forget to drain it and it ended up dripping oil on the rear brake... that was not good. So here is what I am thinking of trying now. What if I tapped a hole into the Forcewinder elbow, added a fitting, and connected my tube to that? Is there a reason why this would not work? Would that direct of a connection cause the bike to try and suck air/oil from the heads constantly? Has anyone tried this? Dear Throbing Brain of Badweb, give my your feedback. Thanks | ||

Sounds more or less the same as the stock setup. Just be careful of the tube running up hill as it could cause oil to pool and block the line. | ||

why not tap the oil tank and run the breatherline back to it. Lol | ||
| Koz5150 |
Well, I thought of that too. I didn't know if running the line back to the oil tank would cause a pressure issue anywhere. | ||

Pretty sure Dueller was kidding there. You do not want the oil/water/air mixture that is the spooge coming from the crankcase vent to go into your oil tank. Burn it by sucking it in to the engine, as OEMs do, or route it to a catch can. | ||

I don't believe there is a cure other than to fit the XB rocker covers and go that way. I might do it myself one day - but I don't thrash the bike like I use to - which is about the best prevention I've come across so far. Rocket in England | ||

How bout putting a catch can in a spot where you see it and not forget to drain it? | ||

I'm thinking about getting a forcewinder setup with the built in tubes that recirculate the blow-by into the intake, whereafter the engine burns it up. Won't this take care of the problem? I keep reading about this dreaded splooge and am wondering why the recirc system won't function just like any car's normal EGR system (i.e. just fine). | ||
| Hootowl |
EGR is not the same as PCV. | ||

Sorry, my bad. I meant PCV. | ||

I have an X1 with a Forcewinder. It was already fitted before I purchased it. Originally it too feed the blowby tube back into the air cleaner and it would on occasions drip some spooge onto the exhaust. I didn’t fancy directing the tube to the ground and potentially messing my garage or some friend’s driveway or worse my rear tyre. So I: - purchased a second hand XB catchcan - attached it to the left hand side vertical frame next to horn on the left-hand side of the bike - used a sintered metal breather that screwed directly into the catch can - disconnected the Forcewinder blowby tube at the existing connection joint (towards the front of the bike) - attached a some good quality fuel line and ran it all downhill and between the cylinders to the catch can on the left of the bike. - purchased the right angle/threaded brass fitting to connect the hose to the catchcan - The line is loosely zip tied to the underside of the intake and this keeps it in place and away from the cylinders - Plugged the hole in the Forcewinder air cleaner with a plastic plug made on my dad’s lathe so it perfectly fitted the hole. 15,000km later and everything is OK. I like having it on the left-hand side as you can easily drain it to either a container or straight onto the ground without getting any mess on the bike. The black XB catchcan is less noticeable and blends into the bike more than some other options. The rubber hose between the cylinders is still as new and shows no signs of moving or any heat damage etc. I don’t get too much spooge in the catchcan these days as I check my oil regularly and keep it at the halfway mark on the dipstick. Anything over halfway and it just spits it out until it settles again at the halfway mark. Cheers | ||

I just run mine stock. Keep an eye on oil levels, as noted above any overfill will simply get spat out. Carb bikes, I lengthen the breather hose so it is inside the carb throat but not touching any moving parts. I get zero drippage because it all goes in the intake. It also lubricates my slide and throttle plate. Remember, fuel is a "dry" liquid as far as lubrication goes. And there are moving parts in a carburetor (and an efi throttle body). If people want to reinvent the wheel and make more work for themselves by using a catch can or oiling their rear tire, that's their call. Stock works just fine for me on all my engines - Buells, mowers, gas cars, and diesel trucks. | ||

No matter how may breathers(rocker arms, crank case, and transmission), IF YOU PUT TOO MUCH OIL IN THE OIL SYSTEM THE ENGINE WILL "PUKE IT OUT" AND/OR "WEEP IT OUT" !!! OIL SYSTEM Class 101, if you want a copy, just PM me ... | ||

Ausx1er, Could you post a picture of your line routing? I have a similar setup but the line rubs on the fins of the engine. Just curious how you accomplished this without the line running uphill or rubbing. Maybe it's because my mounting point for the can is farther forward that yours? I have a Pegasus racing can which doesn't fit on the vertical bar with the breather on top. | ||

No matter how may breathers(rocker arms, crank case, and transmission), IF YOU PUT TOO MUCH OIL IN THE OIL SYSTEM THE ENGINE WILL "PUKE IT OUT" AND/OR "WEEP IT OUT" !!! Absolutely my findings. Having the Metmachex tank I can squeeze over 3 ltr's but over the years I've experimented back to bang on two quarts. Anymore increases rhe risk of blow out dramatically. Rocket in England | ||

A photo as requested. Not the best but you get the idea. It is downhill, helped by mounting the can as low as possible. You can't see much from the other side. I lined up the can so the hose goes straight through the middle without curving and it's zip tied on the other side so it doesn't touch the fins. It all seems to work. But like others have said check oil when hot after a ride don't fill past half way and the catchcan is not really needed. Having said that I like no longer having to put up with the odd drop of spooge dripping from the Forcewinder and sizzling on the exhaust.  | ||

2001 S3T ... This is my final solution for puking. 1) XB Rocker Covers 2) Breather lines run along the left frame tube, tee to join both lines just back from the rear head. 3) Single line follows left frame tube to a 2nd tee, continuing straight through the tee to a Red Bull can tie wrapped behind the license plate holder. 4) Clear line running down from the second tee to a spot just above the oil tank drain. This line is plugged with a bolt. The theory is that the stuff coming out of the PCV valves is pumped as a vapor out these tubes. The hose running into the Red Bull can provides an open line so no back pressure exists. The down tube collects any liquid that condenses out of the vapor. After a few rides, I pull the bolt out of the down tube and drain the liquid accumulated there. There might be 1-2 inches in a 3/8" tube. The Red Bull can takes the place of a breather filter which I always found to be the messiest part. Hope this makes some sense. Barry Hollister, CA | ||

So here is what I built. I found a small brass pipe fitting and tapped a hole in the bottom of my Forcewinder intake.  I then filed down the fittingt o make the airflow path smooth.  Finally I put it all back together.  | ||

I know your main question was how to get away from the catch can but... I installed XB rocker boxes with a catch can- doesnt seem to create as much water/oil mix as before but still some. I can get away with a few rides before draining but try and drain it after i get home from every ride.  this got me to thinking though....I have a filter on the outlet of the catchcan and once in a while lets some mist out.. maybe ill lose the filter and then the hose from the catch can back to my air filter.

I was thinking of doing this as well since the PCV vapors seem to condense on my catch can filter and make a mess. | ||

I turned my road draft tube into a show. I replaced the rubber tubing with clear neoprene so I can watch the baby puke marching out on a cold morning  (Also, the rubber tube rubbed through and I had neoprene on the shelf) |
