From Keiku's Page:

"During his own private training, Keiku energized his body and life force with Cosmic Energy, an exotic energy accessed by the Helixian Clan, which he uses as an alternative to Chakra. Using this energy, Keiku can power techniques that would normally require chakra"

He can use these techniques because Cosmic Energy can be used to power techniques that normally require chakra.

Also:" Using Color Course Change, Keiku has backup reserves of chakra stored in physical clones of his original body, allowing him to fight for extended long periods of time. To clarify, he can actively use the chakra of these 'extra bodies', including the natural energy stored within them, as after all, they are physical clones of him, without having to switch to another body through use of the Physical Clone Technique."
