2. Locate the power valve cover. The power valve cover is located on the left side of the engine, just below the cylinder head.
3. Remove the power valve cover. There are two bolts that hold the power valve cover in place. Once you have removed the bolts, you can lift the cover off of the engine.
4. Inspect the power valve. The power valve is a metal plate with a series of holes in it. These holes allow air to flow into the engine. The size of the holes determines how much air flows into the engine, which in turn affects the engine's power output.
5. Adjust the power valve. If you want to increase the engine's power output, you can enlarge the holes in the power valve. If you want to decrease the engine's power output, you can make the holes smaller.
6. Reinstall the power valve cover. Once you have adjusted the power valve, you can reinstall the power valve cover. Be sure to tighten the bolts securely.
