These aren't like i-phones where you just download the latest update, if you want the most upgraded OE Buell, find a 2010 model. Otherwise ride your bad ass Buell as much as you can and leave the Facebook 'but what IF!!' drama in the computer . IMHO.
But to answer your question. Yes, you can update the drive gear (the pump is a whole other deal) and put in the later crank. For the same cost you could sell yours and spend the difference on an '08-up that has every 'upgrade' you are asking about and more.
OR, since the cranks out, call Hammer Performance about a 1640 kit!
