swapping engines in DHZ dpro from original lifan to GPX help

[I-LOVE_DIRT]

I'm thinkin about putting a new GPX engine in my dpro and thinking about doing it myself, I've previously done it with another lifan engine but unsure on the GPX..

Will I need it tuned once I've put it in or is it as simple as putting it in wiring it up, hooking up the oil cooler and giving the carby a quick adjustment and I'm ready to ride or am I missing something?

Also does anyone know if the oil coolers are simple to connect to the dpro frame or do I need to do some adjustments?
