Taller gearing will only help you in a long track, where you can "use" it, as soon as you are runing a track where you cant stretch that second gear, you are putting more gas in your engine than what the engine is actually using, or "working". the same goes for short gearing on a long track, youll be on the throttle a longer time since the engine "stops pulling" half way through the track.

you need the right gearing for your track, your engine AND!!! the setup you have in it; pipe, fuel, plug, compression, restrictor, etc.
