Gsxr K1 600 Engine swap to K1 750

Hi gixxer maniacs.
I'm gonna swap my old,well served 2001 600engine with a fresh one off K1 750.
Got the engine already in my garage and I can see already there is priming servo on the right hand side of the throttle bodies.

The question is does anyone done this swap before?
Do I need any extra harness or sensors etc before I plug all this in and go for a wheelie?

Thanks
Adis

Bodies and wiring came with the 750 so it's all there.
Yes.So what witch ecu?On one site it says that 600 won't be compatible on the other one it will.I have power commander as well (currently with map for 600 but will upload new one for 750)

What about the air box?Different inlet diameter?

Priming servo I meant throttle servo
I can see there is different one with a small computer (servo itself) on that 750
I don't have that on my 600engine.

You need a 750 ECU - there are more differences than just fueling.

And yes, the 750 intakes are larger.

Just checked in haynes manual and the air box inlets are the same for 600 and 750 K1/K2 .1000cc K1-K2 are different size.

(SVS they are more longer then larger I can see but the diameter is the same)
Anyway thanks a lot with ecu suggestion.
Ride safe

Got ecu today trough the post.
2more days and Im gonna start playing with all that.
Any other suggestions what should I keep my eye on?
The only thing what bothering me is all loom/wiring the same?
As I said before Ive got the whole engine complete with throttle bodies (I cleaned them and they are already fitted) also all electric came with them.
In my opinion all the rest of connectors,plugs,cables etc should be the same (I mean for example coil plug connectors and stuff like that)

Thanks
Adi

Tried airbox today and SVS you was right.There is a difference.
Sorry mate I'm giving back your right.
Off a 600c are slightly smaller intakes.
