2-Speed Adjustment

Although pre-set at the factory, the two-speed can be

adjusted to shift at the point that suits you best. Under normal

circumstances, it should shift well before the engine reaches

maximum power. The actual distance traveled will vary with the

gear ratio and tune of the engine. Tightening the adjustment

screw (turning to the right/clockwise) will make the two-speed

shift later. Loosening the adjustment screw (turning to the left/

counterclockwise) will make the two-speed shift later. Follow

these simple instructions:

1. Place the rear of the chassis on a block so the wheels can

turn freely.

2. Remove the plug at the top right hand side (looking from

the back toward the front) of the transmission case. You

will see the 2-Speed mechanism through the access hole

(Photo 1).

3. Roll the spur gear forward until you can see the hex of the

black setscrew in the inner rotating hub as seen in photo

2 and skip to Step #5. If the adjustment setscrew is not

visible continue on with Step #4.

4. Hold the spur gear and turn the wheels forward slowly

stopping when you can see the hex of the black setscrew.

5. Insert a 5/64-inch hex wrench into the setscrew.

6. Turn the setscrew ½ turn clockwise to make it shift later.

Turn the setscrew ½ turn counterclockwise to make it shift

sooner.

7. Replace the rubber plug.
