Indonesian News One - Now the ability to change, adjust or set the motor does not belong to the people in the workshop. You can mengulik your standard bike to be much faster speed. All you need is a basic understandings of the logic of your engine working principle, and then you can create independently. Consider the following tips:
1 Piston. To modify your motor so that its speed becomes faster, you have to reduce the weight of the piston so that the motor power increases because of energy lost to counter the weight of the piston. To reduce the weight of the piston, you can cut the bottom of the piston, the magnitude of the cut is already certain (sure) and each bike is not the same.
2 Cylinder Head. In the process of modification of your motor, fuel compression space will determine the power generated. In principle, the higher the compression the greater fuel generated power. To enhance the combustion chamber compression can be done by reducing the volume of the combustion chamber. In general motorcycles, this is done by grinding the cylinder head so that the combustion chamber is reduced and increased compression.
4 Electrical System. Electric power to the motor kebyakan 6 volts. Tagangan can be converted to 12 volts by changing the electrical system. With a voltage of 12 volts, the lights become brighter, horn becomes harder and spark plugs become larger.
5. Rocker Arm. Rocker arm or sleeve valve pounder also serves to forward movement of the rod-suppressing (push rod) or from pam shaft so that the valve can open and close. Rocker arm that is both lightweight but strong. If the cuts will result in excessive rocker arm rocker arm to be easily broken.
6 Gears. Motorcycle modif done so that the speed of the motorcycle increases on the same engine power, rear gears should be replaced with a smaller diameter, if the gear is replaced with a smaller wheel Ranta course length should be reduced and tuned.
Jetting Method and Adjusting the carburetor
Because still there and even many who do not know about the carburetor jetting, I try to review more complete.
Done by setting the carburetor adjustment on:
1 The size of the pilot jet
2 The size of the main jet
The position of the jet needle clip 3
4 Setting the air openings
5. Settings stationary
At 3/4 throttle to full the role is main jet and pilot jet. So that would add top speed, replace the pilot jet and main jet. Just buy the pilot jet and main jet with new larger size, continues to plug replaces the old one. Dratnya same size, which is different from an aperture in the middle. So there is no problem of mutually MJ / PJ origin speknya indeed make the same carburetor (Mikuni).
For economical settings, there is an optimum or wasteful in the position of the clip and stationary setting. Not on screw air openings. Air screw is only used to arrange for complete combustion (spark plugs red brick).
So the first set MJ, PJ and clip position. Standard clip position is the middle. If it's OS 150-200 continues want economical, can clip up to the second position from the top. If the highest, worry too economical. If economical, easy to overheat the block and piston-rings can be stuck when using that speeding. Unless using that ibu2 made to doang market, so-so tuned economical consumables .
Furthermore, adjusting the air openings to the gasoline-air mixture optimum result. The sign is the optimum mix of red brick plug color (almost perfect combustion).
Way of setting the air openings:
1 round stationary screw clockwise until the high stasionernya. Spekrup rotate clockwise causes the stationary needle jet lifted. Just by opening the gas, open the gas causes the needle jet lifted. Why should high first? Since the air openings will be closed later discharged, if the needle jet is not quite lifted the engine so dead. So the needle jet should be quite lifted first.
Stationary screw. Clockwise rotation causes the higher stationary. Rotation in the opposite direction caused the idling / stationary lower.
2 Turn the screw clockwise air openings to enter the fixed (closed). During playing, idling / stationary will decrease. When the engine so dead, open the air screw 2 turn, back to the first step and add langsamnya.
Turn the screw clockwise air openings to enter the fixed
3 Turn the screw counterclockwise air aperture (opening), slowly. Observe stasionernya sound (sound exhaust / engine), stationary will increase as the air screw slowly opened. Play continues slowly, and stop when stationary does not want to ride anymore. Then turn the screw clockwise air openings as much as 1/4 round.
Turn the screw counterclockwise air aperture (opening)
Round 4 stationary screw counterclockwise until stasionernya down. Choose a suitable stationary.
Stationary enough / high responsive but cause engine fuel consumption,
less stationary / low lead gasoline efficient but less so resposif (less
power). It's finished his carburetor jetting.
If you have opened many stationary screw or until they run out but do
not want to idle its turun2, it means that the needle hanging. Usually caused throttle cable setting is too wasteful.
Cables can be set to a responsive gas (high idling and wasteful), or for economical (idling almost dead and economical)
