Derbi atlantis "tuning"

Few days ago, I bought a Derbi atlantis just for fun, and because it was cheap. Only 300 euros. But now, I want to make it go faster. I was thinking of this kind of set:

Yasuni C21 racing
Clutch bell stage6
Malossi delta clutch (107mm)
Variomatik Malossi MHR 2008
Carburettor kit Malossi 19mm
Malossi MHR racing 70cc cylinder
+ some springs and stuff for setup

Is that a good set, or should I change something?
