Hi all

Struggling to find info regarding differences on the engines between the 2003 and 2006 model. Only seen guys mention that when swapping a 06 motor into a 03 frame, one needs to fit the 03 throttles on.

Can anyone advise whether there are differences between the engines?

Cylinder head ports are the biggest change.
