Beneli Motor Modification Style
If you are a motorcycle owner who wants to be different, so the first thought is how to spruce alias motor modifications. Then you will start shopping accessories and modifications there here. The longer the more components you replace, and without so many feel is the budget out.
Then you start realizing the function modification more than just enhance the view (pickup). Feels correct any changes cause many effects. From the psychological sense of pride you are, the function of the feeling that you feel have changed. Also in terms of cost, is immeasurable hepeng you spend. The result, the motor you may be more beautiful, but can also even nasty. Function, motor is controlled more easily and much faster, but can also even vice versa: more wild and more weight.
If the negative aspects of these functions appear in more, that means you should begin to evaluate the function of the modifications you make. What is correct way, the components, to modify the workshop. If you are still not the style, you must evaluate, and finishing a model modifications. So you can be a flow, less you shop carefully, or you also may be less serious.
Speaking of the speech is a matter of technology. Use the appropriate components, quality, and maximum work will help the overall motor performance. While talking a matter of appearance, speech is a matter of taste. Modification the only way you know the translation of which will give satisfaction. Modification only component that gives you the good that will maximize motor performance. And, only modification the piawai which will give you feedback as well as the correct concept exist according to a draft budget and agreed upon.
Compression Ratio Modification Style
To increase the power or motor power engine which is called a standard tune up, need to grown the changes on a few things:
1. Improve / increase comparison of compression.
2. Ported to improve the IN and EX importation of fuel to be smoothly and properly.
3. Change the duration, as Noken Lift.
4. Changing the ignition (if allowed in the race).
5. Changing the ratio of the Close Ratio.
6. Carburetor settings.
Compression
Improving the comparative compression (CR = Compretion Ratio) is the way that early adopted by the mechanics to increase engine power. However, to enhance comparison of compression needs to several factors, among others:
1. Fuel used.
2. Quality piston is used.
HOW raise Compression:
1. Changing the piston with a model racing.
2. Juxtapose deck clearance.
3. Head lathe.
4. Teralis Head.
5. Piston block and a lathe.
HOW reduce Compression:
1. Merimer dome at the head.
2. Deepen HOLES the valve on the piston.
3. Piston lathe.
BENEFITS USING HIGH Compression:
1. Increased engine power.
2. Final gear to be heavy.
3. Power from the engine feels lap top to bottom.
LOSS USING HIGH Compression:
1. Machine becomes hot quickly.
2. Engine break into large and coarse.
3. When the calculation of compression is not appropriate, often detonation.
To find out / calculate comparison compression (CR) of one engine, we need to know the first volume of the cylinder will be done.
EXEMPLARY MACHINE ON JUPITER Z O / S 100
Or D Bore: 52 mm = 5.2 Cm
Stroke 54 mm = 5.4 Cm
= 0.785 x 5.22 X 5.42
= 114.62 cc
≈ 115 cc
EXEMPLARY ON JUPITER Z O / S 100
Volume of space with measured fuel buret through plug is 14.55 c
Volume room so toasty 14.55 cc - 0.7 cc = 13.85
(0.7 cc volume space is plug)
How to determine how many cc fuel fill space that we must use the comparison of compression that is we want our to course.example comparison compression 1: 14 is the volume of space fuel?
That means that if we want the comparison of compression 1: 14, the contents space must be roasted 8.84 cc.
4 Stroke Engine Modification Style
1. If point A touches the trigger, the valve began to open up and will be full after a head protrusion (point B).
2. After passing through the peak, the valve back down and closed the meeting after point C.
3. From A to C and then rising and then back to B is called the duration Noken as.
4. Highest Lift determine bulge Max.
5. The form of the surface bulge profile and determine the acceleration of valve closure by the form of the surface profile prominent.
Lift MAX
How to determine the Max Lift the motor racing:
In theory for standard motor, Lift Max is 23% of the diameter in the valve. Then, for the motor racing circuit is not very long, Max Lift approximately 29% - 31% of the diameter in the valve. To race with the long circuit, Max Lift can be studied up to 35% of the diameter of the valve.
Duration
How to calculate the duration of several ways:
1. Duration is calculated after the 1.27 mm valve lift on the valve setting of 0 (zerro).
2. Duration is calculated at the time the valve starts to open the valve on the 0.10 mm.
To facilitate the creation, we will use the second way. Before we want to determine the length of numbers, we must first know how LC (lobe center) on Noken as we will modify.
To know the LC, we must install Noken as the engine and measure with a protractor mounted on the crutch as the left / magnet.
For example:
LC TO JUPITER Z: 103
We want the duration of 310 degrees.
How many degrees in the open and close in degrees?
To Search for a calculation in close:
310 - 180 - 52 = 78
That means that for LC 103 IF WE want duration duration is 301 FIGURES:
IN OPEN BEFORE 52 tma
CLOSE IN 78 AFTER TMB
For the duration of motor racing is ideally 29 - 33.
Max lift for the duration of motor racing is ideally:
7.5 mm - 8.3 mm
Benefits of using a high lift and duration of:
- Power engine to be very large
- Engine is very good on lap top
Loss using a high lift and duration of:
- On lap down less good
- Per the valve does not become a lasting
- Floating valve / float valve when the pear is not strong
- Holes the valve on the piston must be in
HOW hone CAM
- The Base Circle digrinda approximately 18 to meet the desired lift
- Then followed by hone the ram to determine the duration
- Hone the flank lift to determine O / L and form the profile
- Try Kem in the hone with a flat and smooth to ensure that the rocker arm and reducing fixed durable floating.
