Honda CBR 125R 2011 wont idle when cold
 

Was wondering if any of you could help me with my problem. The bike runs fine and drives well but it just wont idle when its cold. Bought it recently and the previous owner said this problem doesnt occur when its warm outside, but when its cold it wont idle.
So far ive tried cleaning the throttle body, cleaning the air filter, checked the fuel filter, checked the battery and adjusted the idle screw. None of these things fixed the problem. I honestly dont even know what to do any more.
The oil kind of smells like gas and when i start up the bike its like i can smell some unburnt fuel, but im not sure. There is also a small crack on the sensor unit on the throttle body.

Any info would be really appreciated.
