Looking for advice/suggestions in regards to swaping out a 600 motor with a 750. I have a 2001 600 and am looking to put a 750 in there... Does it need to be an 01' 750 motor, or can I go with an 02', 03'? Is this a simple swap out, or am I looking at multiple parts beyond taking the old motor out and putting the new one in? Any help is much appreciated, thanks!
