Default Where do they go!

I'm working on an F4i engine and we are trying to hook up the lubrication system (oil connections) and there are two hoses that we have no idea where they go to. We have a service manual but it does not show where the hoses go or what they attach to. they are located directly below the fuel injectors. here are some pictures we took.

I'm not familiar with those connections. Judging by the picture, they go into the head below the intake stacks... but this isn't a 2-stroke and doesn't use oil to lubricate the cylinders... so that doesn't look right to me...

thats kinda what we thought except oil is spitting out of the hoses when the engine cranks. and those hoses are present on all of the engines I have seen for sale on E-bay. is there another component that runs on oil somewhere else on a typical bike? Also I was looking on-line and students from MIT's formula SAE team were talking about an oil de-aeration cylinder that helps remove air from the oil which makes sense because we didn't get oil spitting out of the hose on the left. this is a pic off from an ebay page and you can see the hoses there as well.

Here's more info (it's not really bike-specific, but there's pics on page 5 or 6 i think)

Those look like the air intake vacuum hoses. The should go to the underside of the airbox and I think should be one on each side of the air box.

wait... could those hoses be running to the air cleaner that sits on top of the throttle bodies?

Just by looking at the picture, I think those also go to the airbox on each side
