HELP!

I have an 07 speed triple with 6K on the odometer. Recently ive seen coolant draining out of the down tube. So, I drained all the coolant, along with the brownish gunk in the resivoir tank. I ran water through the system till all I saw draining was water. Then filled it up with the appropriate coolant/water mixture. 1 minute after the bike is on, new coolant started to drain out of the drain tube...what the heck!? Can one of the hoses on the resevior tank be clogged or what? I got no $ to bring it to dealer, and rather fix it myslef anyway. ANY help would be greatly appreciated.
Thanks in advance
