SETTING SHEET

ADJUSTING THE SHIFT POINT

The M-27 2-speed transmission allows the car to have more
punch out of the corners and higher top speed.
We offer many different pinion and spur gear combinations
which can be used for different tracks.

* Adjust the engine before adjusting the clutch shift timing.
Adjust the engine as per engine instruction manual.

1. Once the engine adjustment have been completed, proceed to adjustment
of the clutch shift timing.
(Using a 2mm allen wrench to adjustment the clutch cam.)

Note:
Clockwise--------Shift timing will become slower.
Anticlockwise---Shift timing will become quicker.

2. Adjust the clutch shift timing for your track conditions with 4x4mm set screw.
As you tighten (Clockwise) the 4x4mm set screw , the shift timing will become
slower.
As you loosen (Anticlockwise ) the 4x4mm set screw, the shift timing will
become quicker.

3. Set the shift timing to the track conditions while the car is running.

* Use a 2mm allen wrench to
