SETTING FOR SOKBREKER SKUTIK RACING

Want to share in the scooter race? Do not just performance machine that must be addressed. Handling besutan also be important. "Because if it is baseball taken into account, it will greatly affect the concentration of the driver," said Mariasan pocket, national racer who now 'menukangi' JP Racing scooter racing team.
Talking about the handling, then the focus of concern on the part sokbreker (front and rear). How does the character fit shock absorber devices, create bulldoze small Sentul circuit? Consider the following.
Sokbreker Home
What made the manufacturer for the quasi-front, of course for driving comfort and not for racing purposes. Therefore make use of extreme racing at the track, there should be an adjustment. "What is clear quasi must be set to effect his swing harder. So when worn corners bulldoze more stable, "said driver this svelte berpostur seeded class.

At Yamaha Mio and Suzuki Spin adjustments used by adding a special oil into the tube tomorrow. Number of additional fluid is inserted about 30-50 cc. "That's for each tube, yes," explained Aldhie, from Bike.rider Shop on Jl. Kalimalang, Jaktim. Oh yes for the oil that comes into the front of the tube sokbreker either the left or right fitting size, it would be good when adding all the new oil change tomorrow (Fig.1). For how to change the oil when baseball is different from the standard oil change tomorrow.
In addition to adding the oil, there are also ways you can do. Lowering the bar high tomorrow, is also able to create effects such quasi swing so much harder (Fig.2). "At the most pretentious bar 15 mm lower. The trick to loosen the stem binder bolt pretentious, then push self up, "said this white man.
Make Honda Vario but can use the same trick with Mio and Spin, there are also other tricks which can be used. Replacing a quasi-standard with a Honda Karisma, will make the next quasi Vario harder. "Although baseball as much as when used as the standard, replace oil as well as of innate charisma still have to be increased," said Marko, call Mariasan pocket.

Rear sokbreker
Louder than the factory default should also be applied to make the application on the stern. If the condition of quasi-back is too soft, then when hitting the corner made by a lot of swing.
"Conversely, if too loud, turn out the gas when opened traction tires with asphalt path will be reduced. As a result mounts can twist out tracks, "said Marko. So to overcome this problem, the solution could be to use quasi-back aftermarket with violence as that can be set. (Fig.3). So when drivers feel a rebound tomorrow too hard, then swing as can be softened.
"It would be pretentious yahud when select the violence as a rebound in the pipe or flute can be tuned as desired drivers," said the man weighs 51 kg. Make adjustments violence as, the setting played right then swing as it would be hard. Thus even when you set the rebound on the pipe flute. Rotated right means membaut rebound harder (Fig.4).
Problem quasi aftermarket price for scooter racing, at accessory shops banderolnya $ 500 thousand to Rp 1.5 million.

4 NO MOTOR SETTING

To increase the power or engine power standard commonly referred to tune up, needs to be put the changes on several things:

   
1. Increase / raise the compression ratio.
   
2. IN or EX ported fix to fuel revenue to be smooth and good.
   
3. Changing the duration, Elevator Noken as.
   
4. Changing the ignition (if the race is allowed).
   
5. Change the ratio with Close Ratio.
   
6. Setting the carburetor.
COMPRESSION
Increasing the compression ratio (Compretion Ratio = CR) is a way of beginning to be taken by the mechanics to increase engine power. However, to increase the compression ratio to consider several factors, among others:

   
1. Fuel used.
   
2. Quality piston used.
Through increased COMPRESSION:

   
1. Replacing the piston with model racing.
   
2. Closer deck clearance.
   
3. Head lathe.
   
4. Weld Head.
   
5. Lathe Block and Piston.
HOW TO REDUCE COMPRESSION:

   
1. Merimer dome on the head.
   
2. Deepening coakan valve on the piston.
   
3. Piston lathe.
ADVANTAGES OF USING HIGH COMPRESSION:

   
1. Increased engine power.
   
2. Final gear becomes heavy.
   
3. Power engine feels from the round bottom to top.
LOSSES USING HIGH COMPRESSION:

   
1. Machine becomes hot quickly.
   
2. Engine break into a big and rough.
   
3. If the compression is not precise calculations, frequent detonation.
To calculate the compression ratio (CR) from one machine, we need to know the cylinder volume will be done.
EXAMPLES OF MACHINE JUPITER Z O / S 100
Bore or D: 52 mm = 5.2 cm
Stroke 54 mm = 5.4 cm
= 0.785 x 5.22 x 5.42
= 114.62 cc
≈ 115 cc
EXAMPLES OF JUPITER Z O / S 100
The volume of the combustion chamber through the spark plug was measured with a burette is 14.55 c
So the combustion chamber volume 14.55 cc - 0.7 cc = 13.85
(0.7 cc is Volume Space Busi)
How to determine how many cc of the contents of the combustion chamber that we must use the compression ratio we have set.
Suppose we want a compression ratio of 1: 14 what is the volume of space fuel?
That means if we want a compression ratio of 1: 14, the content must be 8.84 cc combustion chamber.
Ported
The purpose of changing the port is an attempt to enhance or improve volumetric efficiency by optimizing the flow of gas into the combustion chamber.
There are 3 factors that determine the amount of power on a machine:
1. Engine efficiency
namely how a boost in the piston torque generated by the fly wheel.
2. Thermal efficiency (heat)
ie how much fuel to be burned / heated in the cylinder to push the piston down to the TMB efficiently.
3. Volumetric Efficiency
which makes the channel / the right size for optimal gas pump.
