Without any modifications or extra parts use a 78 spur to the biggest pinion possible. ae will have a 72 and 75 spur out soon. A lot of people use a slipper eliminator or combine older parts to use standard spurs and use around 65-69 spur to a 32-36 pinion.

Go that way really fast... if something gets in your way... TURN!

I was running the Slipper eliminator from the link above. I ran a 69/35 gearing and it really brought the 17.5 motor to life.
