Kuryakyn do not do a specific hypercharger for your year of bike, you need to buy just the HC from Kuryakyn and then get the bike specific adapter, not to sure on which yours is but would suggest its the EVO not the twin cam

You have an EVO but before you commit to the hypercharger http://www.hdtalking.com/fuel_and_ca..._kuryakyn.html

I don't know how true it is but it is something to think about
