Carbs are smoother as the fuel is gravity fed not forced in like on the injector models. I have had a (00) and an (04) bike and I can say that performance wise there is not much difference. I think I might even prefer the carbs over the injection system but as I ride in winter the new bike is a little better in the cold.
If your happy with your bike then keep it, you wont get anything more than a slighly better looking bike by getting a pointy with EFI.
