Terry, also with 8:1's it will take a lot of amps (torque) to pull the wheels up. Jumping from 12.44:1 to 8's kills your low end torque and most of the guys pulling the wheels up are pushing much more than 500 amps. I wouldn't worry, you're losing mph when they pop up....but, I does look cool! Do you spin the wheels pretty good? If so a taller tire may give you a wheelie. If the power is there the small tire will break lose, larger tire will have more traction and lift it up. Reverse??? Spin your axle around and drive in reverse!! Just undo the 1/2 speed cable!
