Why do you hear an apical beat in systole?
The systole is when the left ventricle contracts and produces a stroke volume that is felt as a pulse. This is part of the measurement of a blood pressure reading. The reason you hear the 'lubb' sound is because the ventricle contractions are stronger than the atrial contractions. The 'dupp' sound is when the ventricles relax, so the sound is softer. Both sounds, or small upward blips on the sphygmomometer dial is due to the closing of, first, the atrioventricular valves for systole, and then the closing of the pulmonary semilunar valves for the diastole.
Caffeine is a stimulant which will cause an increase in heart rate. This increase should just be temporary, like the increase during exercise. Usually with an increase in HR, there is an increase in BP. As for severely increase, it shouldn't but it will depend on how much caffeine your talking about. Its always best to ask the pediatrician.

How do you adjust the intake valves on a 1992 Yamaha PW80 and where are these valves located?
The truth of it is, if you don't know where they are located you should not be "adjusting" them. It is a delicate process that, when done incorrectly, can lead to terrible damage. A valve adjustment by a qualified mechanic should cost you no more than around 40 bucks if you're willing to wait in line. I don't intend to sound like I'm cutting you off at the knees, it's just that this is "how it is".
new answer : actually a pw 50 & 80 are 2 stroke it doesn't have normal valves it has reed valves between the head and carb. they are nonadjustable
Yes. Correct. The PW50 and PW80 are 2 strokes and do not have valves in their engines. Their only valve is the reed valve between the carburettor and intake and cant be adjusted.

What is the proper way of computing your heart rate?
The easiest and fastest way is to find a pulse point on your body and measure it using a watch or clock for 30 or 60 seconds. The easiest pulse point for you to measure yourself is on the thumb side of your wrist. Gently place your index, middle, and ring finger over this area until you feel your pulse. Using a watch or clock count the pulsating sensation you feel for 30 seconds and multiple that number by 2, or count for a full minute or 60 seconds. This measurement is known as your bpm (beats per minute) or your heart rate per minute/resting heart rate. It is also essential that you take your measurement in a resting state to get the correct results.
What part of the heart act like a dam which control blood flow in the heart?
