'08-'10 models had a ton of updates that are worth spending a little extra dough for.
-IAC unit eliminates the need for TPS resets. (a huge plus!)
-New oil pump & cams #3, #4 (drive oil pump)
-New flywheel & front primary sprocket
-More efficient oil cooler
-Auxiliary plug for heated grips
-CKP sensor eliminates static timing
And updates also include (but can be fitted on '03-'07);
-New pivot shaft
-Pistons to allow for higher redline
-Headgasket
