you need these gears for the tornado 2 speeds: http://www.clermontmotorsports.com/s...le-gear/Detail and http://www.clermontmotorsports.com/s...le-gear/Detail .

if you want the single speed, get this, i have it in one of my tornado's: http://www.clermontmotorsports.com/s...als/Categories its a direct fit and everything is included to do the swap.

for some reason, the 2 speed dont shift all the time, i have replaced my shifter a few times already on my 2 speed redcats
