2004 R6 body....will a 2005 R6 Engine work?

I have a 2004 r6 and I'm having compression issues with my current engine so I was going to purchase a 2005 motor and put it in place of the bad motor. Will it work or will I have problems?

Thank you

it's the same bike. however, there were 2 changes to the 05 that will require you use parts from your 04. the 05 has larger throttle bodies and required a different map in the ecu. just swap your system to the 05 motor. you will need the intake boots from the 04 too. if you try to use the 05 throttle bodies you will need a 05 map and the air filter housing boots to fit the 05 throttle bodies.
so those 2 things is all you will need to change around.
