Spoiler:

At that time, Kyuubi's chakra was in the picture, helping him gathering extra chakra and healing him. Right now, it is different, he is either not using it or not using it a lot.

There is also the case of going to extreme with the jutsu, doing something he hasn't done before, or forcing something in the way he hasn't forced before.
