The decompressor lever on a Royal Enfield motorcycle is typically used to relieve the compression in the engine's cylinder when starting the bike, especially on older models with single-cylinder engines. It makes it easier to turn the engine over by reducing the force needed to rotate the engine when starting it, especially in cold conditions or when the engine has higher compression.
Here’s a quick breakdown:
-
Purpose: It temporarily reduces the compression inside the cylinder by opening the exhaust valve slightly, which allows for easier starting. This is particularly useful for older models with higher compression ratios, where manual starting could be difficult.
-
Location: The lever is usually found near the handlebar, sometimes on the left side, depending on the model. On some classic models, it’s a mechanical lever that connects to a cable system attached to the engine.
-
How to Use:
- Pull the decompressor lever before you attempt to start the bike.
- After the engine has been cranked a few times and is ready to fire, release the lever.
- The engine should then return to normal compression.
-
Model Variations: Not all modern Royal Enfield bikes have decompressor levers. Newer models tend to have electronic or automatic decompression systems, which do not require manual intervention.
