the stock ones for the tornado are 47 42
the lightning uses 44 39

edit; also dont loosen the screw for the 2nd gear until after you tune it cause it might not be goin fast enough to engage 2nd gear
if it still doent work when you lossen shift screw be very careful cause there is a little spring in there and it WILL go flying so when you find the right spot make sure to use loctite cause the can and will vibrate out while driving hope this helps
