If you want to increase low-end torque to launch a heavy bike from a stop, or top-end horsepower for HARLEY-DAVIDSON CAMSgreater top speed, choosing the appropriate cam configuration will help you achieve the desired Nevertheless, these variables are critical in determining not only an engine's maximum power output but also the shape of its power curve. In the quest for maximum power output, many-too-many Harley owners choose a late closing, high-rpm cam for their engine. The camshaft uses lobes (called cams) that push against the valves to open them as the camshaft rotates; springs on the valves return them to their closed position. What is the camshaft, what does it do and how can it be modified. It turns out that there is a direct relationship between the shape of the cam lobes and the way the engine performs in different speed ranges. During closing arguments in the trial challenging NYPD policies with respect to Terry stops, District Judge Shira Scheindlin said she was "intrigued" by the idea of police using body cams for all stops. The key parts of any camshaft are the lobes. If the intake is not open for sufficiently long a time or the exhaust valves open early much of the power from the engine will be gone. If you want to increase low-end torque to launch a heavy bike from a stop, or top-end horsepower for greater top speed, choosing the appropriate cam configuration will help you achieve the desired performance results. Duration is the amount of time a valve is opened and is measured in crankshaft degrees. Fast road cams (Sports camshafts). Here are Mikuni North America gave me a nice guide that I have used in cam choices for a long time. As the camshaft spins, the lobes open and close the intake and exhaust valves in time with the motion of the piston. Using the highest lift, longest duration cams, are not always your best choice. Even though in some combinations they can work very, very well, using them with components that are not designed to compliment the cam can often disappoint. Of course A while back, I submitted an op- ed to the New York Times on officer-mounted cameras. It was rejected, but I got a nice email from them saying that they were close to accepting it, but it lacked a sufficient opinion. But keep in mind that the Nevertheless, these variables are critical in determining not only an engine's maximum power output but also the shape of its power curve.
