03+ differences?

I searched and didnt see any posts about this. Figured it would be a sticky.

I know the hydro brakes front and rear, which changed the front hubs, spindles, and the a-arm, swing arm, and frame slightly. New front hood/headlight, which probably changed the steering stem. And the carb has a different needle.
Is that pretty much it? The reason I ask is I've seen people posting 03+ motors, and 03+ seat I think it was.

It was mostly the 03+ motor that threw me off as I thought the motors were all the same?

I looked at a parts fische for a 94 and 04 and the cases, clutch components looked to be same part numbers.

One big difference with the engine is the stator and CDI, 5 wire as opposed to 4. TORS brain is in the CDI instead of under the hood. Stem is same, little modification needed to fit it.
