so i have a 5 speed ex, but i want a 6 speed, and im tired of red lining at such low speeds!! is it possible to get different sized gears? cause ive noticed i only drop about 800 rpm when i shift, id like at least 1.5k per shift, with at least a 2k drop for 6th. i searched the forum for something like this, but it looks like im the first..... does that mean its not something you do?
