Is there any differance between a 2003 and a 2005 636 motor??? I have a 2005 but I have the chance to pick up a 2003 motor with less then 1000 miles on it super cheap as a spare just wondering if they were the same or what the differances were.
I beleieve the 03' and 05' share the same cases and external dimensions, but the 05' has the cams from the 03' race kit, and it also has different fuel injection and throttle body assembly. I also think the 05' frame might be different, or it might just be the anodized black that's throwing me off, either way it's worth lokking into.
