Any Suggestions on engine?

I have a pit pro 125rr but im thinkin of gettin a pitpro 140 or 150, if i dont end up doing that i will just get a new engine so i was wondering what engine is the one to go for. I want something with insane power i've heard of some engines like the GPX 160CC, YX 160CC.

dont know if youll ever get 'insane' power, but ive got the yx 150 and thats not too bad an engine, i havent had any problems with it yet.

what are the lifan engine's like compared to gpx and yx engines

iv heard the lifans go pretty good but i use to have a yx 150 and that was pretty damn quick on the dirt and pretty psycho on the hard stuff it would pick up the front from second to third and if you give it enough it will do it into fourth to.
