Triumph daytona 675 strange cold problem?

its winter here and reguarly around 30 to 40 degrees f. my bike will only start if i put a space heater near the starter and warm up the crank case other wise it just clicks once and the electronic fuel injector resets and pumps another pump, its not like the starter is clicking like they do when the batery is dead. and its not even trying to turn over the engine it just clicks and resets and doesnt alow me to attempt to start again until some fan shuts of. i used to think it was because the batterys voltage was low so i bought a tricle charger and it seemed to help but still happened so i had the bat checked and it turned out to have one bad cell so i replaced it and thought my problems wer solved but now its happening more often. if i heat it up and start it and run it it starts again and again no problem but if left to long in the cold it has problems. also iv noticed that when it does attemp to start it needs the throttle pulled allitle bit even though its fuel injected wich is strange. and when it does attempt to start it seems to be taking longer than usual like the engne cranks over quite a few times before actualy fireing up? any one expirience the cold problem? is it just the cold or is it somthing bigger? thank you
