Check engine tune. i.e. cylinder compressions, spark plugs. ignition timing, carburetters.
Using a suitable Allen key, remove the blanking plug (1, Fig. 76) from the gearcase.

Run the engine until it reaches normal operating temperature.
Chock the wheels and apply hand- and foot- brakes.
Select "D"; pressure gauge should read 3.85 to 5.3 kgf/cm2 (55 to 75 lbf./in2) at idling speed.
Increase engine speed by 500 rev/min, gauge should read 5.3 to 8.1 kgf/cm2 (75 to 115 lbf./in2).
There must be a difference of 1.4to 1.76 kgf/cm2 (20 to 25 lbf./in2) in the two readings taken.
The lower figure must not exceed 5.3 kgf/cm2 (75 lbf./in2).
If above readings are not obtained, proceed as follows.
WARNING: Engine must be switched off and selector lever in "N" before carrying out adjustment.
