Three Ways to Increase Energy Of Motorcycle with Bore Up
So far, not least among motorcycle owners who improve energy with Bore up their mounts. How, by changing the piston size for the volume of fuel and air are sprayed into ?combustion chamber getting bigger.
As a result, the more perfect combustion with a high compression ratio. This method was chosen many modifiers and motorcycle owners. The reason, in addition to practical, cost to be incurred is also cheaper.
Only, not a few others who do not get results as expected. In addition to energy does not increase dramatically, also holds the potential danger.
“Power is increased, but only 20-30 percent. However, if the right way, power can be increased by 50-70 percent. In addition, if not actually damaged the right engine,” said Setyawan, mechanical Cloud Motor, Panjang street, Kebon Jeruk, West Jakarta Tuesday (15 / 3).
So what should be considered? Step what to do? Here are tips from Setyawan.
1. Make sure the diameter of the cylinder in accordance
One thing that must be considered before doing the bore-up is to ensure maximum diameter of the cylinder when enlarged. Bore up techniques are of two kinds, namely original cylinder Bore up with an enlarged diameter.
The second technique by replacing the cylinder liner. If you want to replace the cylinder liner, then need to be considered safe limits Bore up, so that no components or other parts of the machine to be sacrificed in vain for the sake of enlarging the cylinder.
“This is important because each type or brand of motorcycles have different thicknesses,” said Setyawan.
When the diameter of the cylinder is not possible to be enlarged and enforced, it is not impossible will be broken. Of course it is very dangerous.
2. Calculate return the machine capacity
After ascertaining the thickness of the cylinder which makes it possible to be enlarged, the next step is to calculate or re-cc engine capacity motorcycle engines. Do the calculations – would ask an expert or understand the engine – how big is the volume of the combustion chamber.
Then, count up how much the ability of that space when it’s done by increasing capacity. “So far, the public began adding the modifier 0.25 millimeter (mm) up to 1 mm,” explained Setyawan.
This step should be extra cautious and careful. Because if haphazard, then the capacity would be precisely sized space is too big. As a result, the combustion chamber to produce excessive heat, so that the piston jammed or broken cylinder block.
If that happens then the motor will stop suddenly when driven hard and bounced. Any engine on fire and can spread to all parts of the vehicle.
3. Calculate carefully re-heat engines and compression ratio
After these two steps done and mechanical or modifier stated okay, the next step is to calculate the ratio of heat engines and compression ratio. It means knowing exactly how much pressure in the combustion chamber than the fuel intake velocity, air turbulence, a mixture of air and fuel are ideal.
“The pressure of compression is the average effective pressure that occur in the combustion chamber just above the piston,” said Setyawan.
When the compression pressure and the pressure of an ideal heat in the engine – usually a large workshop using compression gauge measuring tool to know – is well known, and allow it to do Bore up the mechanic can do it.
The ideal size and compression level of heat for each type and brand of different motors. Manufacturers usually provide a limit by stating the size of Upper Dead Point of the level of heat combustion chamber, and include the level of compression engine in the manual.
Remember, the combustion chamber that is too large than the standard set by the factory will also not be good. In addition to wasteful also cause heat that is too high so that the piston jammed and cracked or broken cylinder block.
So far, the modifiers for motor racing in the streets often cut the head of the piston to increase compression engine. The amount varies, for two-stroke motors are usually 1-2 mm, and four-stroke motors 0.5-1mm.
