For a new engine (break-in setting), the high speed needle needs to be set as rich as possible.

Turn the high speed needle 1/4 turn counterclockwise from initial setting (2.5 turns from fully

closed). Repeat step 17b. Keep doing this until the engine stalls at full throttle, then turn the high

speed needle 1/4 turn clockwise. Run the car in an open parking lot with this rich engine setting for

at least 5 tanks of fuel to complete the break-in process. It is normal for a new engine to stall during

this due to the rich setting. When it does, just restart the engine. After break-in, follow the ENGINE

SETTING procedure to set the carburetor for normal operations.

ENGINE SETTING

Due to different fuel formula, operating elevation, humidity . . . etc., the engine may/may not

operate properly at initial setting. Please follow the following procedure to achieve proper

carburetor setting. Do not perform this procedure until the engine has been properly broken in.

a. Start the engine.

b. With a running engine, run the bike back and forth in a straight line (full throttle achieved in each

pass) in an open parking lot. Repeat and note the sound of the exhaust. Do not hold the throttle

open with the bike of the ground as this may cause the con rod to break.

c. If the exhaust does not reach a high pitch note, turn the high speed needle (long needle,

extending from carburetor body, pointing up) 1/4 turn clockwise, and repeat step 17b.

d. Repeat step 17c until the engine reaches optimum setting (turning in the high speed needle will

no longer have an effect at full throttle and turning out the needle will cause the engine's full

throttle rpm to drop a little). For normal operations, turn the high speed needle 1/4 turn

counterclockwise from the optimum setting.

e. To set the idle, turn the idle screw in (higher rpm) or out (lower rpm). Basically, the idle needs to

be set at the lowest possible point before the engine stalls.

f. To set the low speed needle (inside the throttle lever), the engine needs to be broken in and high

speed needle needs to be set first.

g. Repeating step 17b every 10 seconds (1 second full throttle and 10 seconds idle). If the engine

rpm at idle drops after a few seconds and stalls, then turn in the low speed needle (clockwise)

1/4 turn. If the engine rpm stays the same or goes up at idle, then turn out the low speed needle

(counterclockwise) 1/4 turn.

h. Keep repeating step 17g until the engine rpm drops (goes to idle rpm, then drops a few more

rpm after a few seconds) but does not stall.

ENGINE BREAK-IN

a. Hold the transmitter with one hand, finger on throttle.

b. With the other hand hold the bike. And then give it throttle while you push the bike a little. The

motorbike goes away in a straight line. Then you reach for the steering control and the fun begins.

c. When cornering, slow down the speed to make the turn easier then re-apply the power on the way out

of the curve.

d. If the bike falls due to loss of balance, the side guard wire will support and prevent the body from

scraping.

e. To continue the motorbike's running, technically give it a slightly more throttle to help the motorbike

back to the balanced running.(Note: Do not give the throttle too much as this will create a spin.)

OPERATION TIPS

1. Always turn off the radio system and unplug the battery pack when not using the bike. Remove the

battery pack when storing the bike

2. Ensure the bike is cleaned down before the bike is stored for any period of time.

3. Ensure all fuel is removed from the fuel tank before bike is stored away.
