Kuryakyn Hypercharger Kit for 2007 -Present Sportsters
Normally, replacing a stock air cleaner with a Hypercharger will net you a 7-9 horsepower increase at the rear wheel, with no other modifications!
Add a carb recalibration kit, a good performance exhaust system (not drag pipes) and a 12-14 horsepower increase is normal.
