Try to pick the right parts

#1
So I am trying to pick a hop up kit for my Baja MB 165, I am just starting with the stage one kit. I am a little confused what to select for my engine type when attempting to purchase this. I have the Hensim 6.5 clone but the choices are not that specific.

GX200
Yellow, Red, & Most Clone
Blue (Lifan) 5-bolt Clone
212 Predator (Old Style with Stamped Valve Cover)
212 Predator, New Style w/Hemi Head (-$10)
GX160

Hop Up Kit, GX200, 6.5 Clones, & Predators, Stage 1
