Got the Q4 & Power Bomb with all the carb / airbox mods. If you think its good now try changing the gearing to 13/45 and you will experience a new level of performance bliss!

By far, the gearing change was one of the most noticeable improvements to the off-road performance of this bike. You could probably even go 13/46 or 13/48 but you might be cutting into the street worthiness.
