Porting helps make the overall process of burning fuel a much simpler, faster, and more effective process. When exhaust gases are able to leave the engine quickly, it helps decrease backpressure, minimizing resistance and pressure loss. Just like porting the intake port helps a larger amount of air enter a motorized bicycle engine at a much faster rate, porting the exhaust port helps the engine expel fumes at a more efficient rate, as well. This makes it easier for the fuel to combine with the air, which improves the engine’s ability to burn this fuel. Greater Fuel Efficiency Larger intake ports allow air to enter your 2-stroke engine quickly. This allows more air to be combined with the fuel within the 2-stroke engine, which means more of this mixture is burned, creating more pressure and thus more power. Here’s how: More Power If you enlarge the intake ports on your 2-stroke engine, they will be able to take in larger amounts of fresh air when the piston is compressed. Why Porting Helps Your 2-Stroke Engine Porting helps motorized bicycle engines create more power, burn fuel more efficiently, and last longer over time. This process is usually followed up by polishing, which smooths these ports to help air enter more efficiently and with less turbulence - we’ll get to that a little later. Though engines try to do this process naturally, a ported 2-stroke engine will do it more effectively. Intake ports take in air and fuel and mix them properly while the exhaust ports release fumes as efficiently as possible. The intake and exhaust ports are essential to the performance of your motorized bike. As a rule, when porting and polishing your 2-stroke engine cylinder, you’re attempting to match the size of the intake manifold and intake port, as well as the exhaust manifold and exhaust port. What Is Porting? Porting refers to the process of enlarging and shaping the intake, exhaust, and transfer ports around the cylinder of your 2-stroke engine. In this guide, we’ll talk about what porting and polishing are, and what you’ll need to properly port and polish your 2-stroke engine. The great thing about porting and polishing your motorized bicycle engine is that it’s a reasonable and inexpensive way to boost your engine’s power. While adding performance parts to a motor can increase speed, it's porting and polishing your 2-stroke bike engine that’s going to improve its performance regardless of parts. One of the best methods of improving the performance of your motorized bicycle without buying high performance upgrades is porting and polishing your 2-stroke engine.
