how to made a good torque

L = (850 x ET) / MAX RPM - 3

L = length of exhaust pipe that will be made
ET = Exhaust Timing, when the exhaust valve starts to open before the BDP (bottom dead point)
MAX RPM = RPM (radians per minute / spin machine) that you wanted to get the peak of power

example:

My motor starts when the discharge opening 80 degrees before the BDP, then the calculation is
L = (850 x 260) / 12,000-3
L = 19.1 inches = 485 mm

Then find the calculation for the exhaust pipe diameter required =
D = sqrt (CC / ((L + 3) x 25)) x 2.1

D is the diameter of the pipe the desired
CC is a cylinder capacity
L is the length of the exhaust

Then the diameter of the exhaust pipe for my bike is:
D = sqrt (171 / ((19.1 + 3) x 25)) x 2.1
D = 29 mm

formula above is an excerpt from the book A.A. Graham Bell, the numbers 260 from the number ex plus 180 degree opening

Vc = ( pi x (D ²) x S )/ 4

Vc (volume cylinder / CC)
pi = 3.14
D = diameter of the bore / piston
s = stroke / step on the piston (units are centimeters). example: satria F 150 stroke's 4.88 just like a shogun 110.

example:

my motoride stroke is 61,4mm and bore 58.40mm

Vc= (3.14 x (6.10²) x 5,84))/4
Vc= 170,6 cc

Blood flow is the key to preventing premature ejaculation. "The point is to maintain blood flow," says Ayoob. "To do so, he must have low blood pressure and arteries are not clogged," he was quoted as saying of Revolution Health. Here are seven super foods which, according to Ayoob can make healthy sperm: Salmon Salmon would like omega 3, which can lower high cholesterol levels (bad) in the body. This fish also contains man
