What pipe are the you running? The Gnarly signs off early but provides lots of bottom. Other than that, jetting as usual can have a big effect as can tired reeds. Might be worth checking base gaskets - often people go thin for bottom end. It's a fairly well balanced engine and if there's no faults should provide plenty of top but you can apply a whole load of tweaks to adjust the power characteristics - pipe, reeds, jetting, base gaskets, flywheel, timing, PV cover, end can etc. Naturally check for faults first. I'm not the best person to advise on this though as I don't need top end for my riding.
