The banshee makes a decent amount of power out of the box, If you want a good performer, mabee spend a little on the suspension & the bike itself....get the power to the ground, a good set of tires, A-arms, widened rear and a set of shocks will make a drastic improvement. Im the engine department a lghtened flywheel, 28-30mm carbs, V3's or carbon reeds and modded cages, air filter, decked stock or cool head for added compression, a fresh top end, and advanced timing will also make a huge differance.
