Camshaft can be referred as the heart of engine since it controls the admission of mixture of air and fuel. Therefore, the shape of camshaft consists of many important aspects that should be concerned by the engineers which are lift, duration, lob separation angle, overlap and etc. Each of the parameter that we change will give a big transformation to the torque and horsepower. The purposes of this study are to compare different camshaft profile design and also to study the effect of the camshaft profile on the torque and horsepower of the engine. For this project I will use Yamaha LC 135 motorcycle to run dyno. Three types of camshaft will be used to obtain torque and horsepower result, the camshaft used is standard camshaft, low camshaft and high camshaft. Before dynamometer test were conducted, the motorcycle must be in good condition to avoid from inaccurate result. So the wear and tear part must be change, then can proceed with dynamometer test. The overall highest result for torque is standard camshaft and for horsepower is high camshaft. From that we can know that different characteristic of camshaft lobe can generate different torque and power at certain RPM. Therefore, the characteristic of camshaft determine how long the valve will open and this related with entering of air fuel mixture into combustion chamber. At low rpm the shorter time valve opening is sufficient for efficient combustion to occur since the movement of piston is slow while at high rpm there will need a longer time to open the valve for efficient combustion to occur as the piston and other part moving faster.
