Radiator to throttle body hoses?

So i'm in the middle of putting my 03 r6 back together after swapping engines, but I've run into a small problem. In the top right corner of the radiator there are three nipples for hoses, I know the top one goes to the coolant reservoir, and according to the service manual, the bottom two are throttle body hoses, but I don't know where they would connect to on the throttle bodies. I've searched all over the internet but i can't find anything.

Re: Radiator to throttle body hoses?

If the design is similar enough to mine, those hoses run to the auto-choke, which is attached to the throttle body. See attached photos. You'll need another post before you can see forum links and photos. (there's a dedicated thread for reaching a 5 post count and if it gets deleted, just create another) I don't think it matters which hose is at the top or bottom, but as apart of any first time teardown, I take a myriad of photos and sometimes mark things. Routing, and making sure that this or that isn't laying on hot this or potentially wet that; or chafing against something is very important on a motorcycle.
