If your bike isn't starting because it's 55F, which unless the converter is off is 12c, changing it to injection isn't going to help, there's a bigger issue there. Carbs, EFI, shouldn't matter, at that temp (which is warmer than what I'd leave to go to work in when I had my carb 250) I had to use the choke for about 2 minutes until the bike warmed up and then it was sweet. I never had any issues starting.

tl:dr: If it's not starting even with choke at that temperature, there is a bigger issue then EFI v Carb.

e: take it to a shop and get it tuned and checked out with that money instead, and then spend the leftover $500 - $600 on other poo poo.
