     Cataract2 |
I opened up my airbox to see if the snorkel had been left in when I got the race kit installed. It was not. (Another point for the dealership) While I was in there I noticed a small amount of oil inside of the area where the air filter is. There were two small rubber pipes coming up and it was on the bottom one of the left. Is this normal or do I have an intake leak? | ||

It's normal. | ||

What causes it? | ||
| Rocketsprink |
crankcase breathing system. that's right out of the service manual I'm looking at. | ||

Ok, is there anything I can do to stop it? Kinda don't like seeing it but that's just me. | ||

Not really. It's an emissions thing, but you MIGHT be able to relocate the breather. I THINK American Sport Bike sells something for that, but it is normal. I just wipe it out every once in a while. You aren't saying it's like a quart of oil, so I personally wouldn't worry. Just ride! | ||

Relocate the breather hoses into a puke can of some sort. It's a mix of condensed water and oil vapor. American Sport Bike might have something or you could mount a Jaz can (it has a cool drain) but the catch cans have their own problems and tend to just re-locate the mess. | ||

Absolutely normal. I spent years putzing with this on my Cyclone, and am relieved to now just leave it be on the XB. They don't blow nearly as much oil out as the tubers did. Just ignore them and ride the bike. | ||

It's normal. The breathers are basically like pcv valves in cars. I rerouted mine to a catch "tube" of clear plastic, instead of a catch can. I did it because the way I look at it, you have: 1. hot air introduced into the intake through those 2 tubes, 2. dirty oil clogging up your filter unnecessarily, and 3. the oily mess that you described. It surely can't hurt to eliminate all that. I have pictures of mine somewhere. I can post them if you want. Mike. | ||

I kinda like the fact that it pushes a little oil into the intake. Guaranteed top ring lubrication  | ||

This is a pic of the rerouted hose before routing it through the frame. I routed it to end up behind the left footpeg bracket where the fuel vent hose also exits. I used clear tubing on the end so I could see what was accumulating:  This was how I solved the problem of the open breather hose inlets in the airbox baseplate:  What I have found is that I get about an inch of liquid in the collector tube after about 200 miles of riding or so. Most of the liquid is clear with no particlar odor so I think it is mostly water. I get only a thin, broken film of dirty oil on top of the water. Now all I need is to put a filter on the tee to keep oil from spewing onto the swingarm! Mike.  (Message edited by xb9er on December 02, 2004) |
