How can you fix gy6 engine tappind noise?

To fix tapping noise in a GY6 engine, first, check the valve clearances and adjust them to the manufacturer's specifications, as improper clearance can cause tapping. Next, inspect the camshaft and valve lifters for wear or damage, replacing any faulty components. Additionally, ensure that the engine is properly lubricated, as low oil levels or dirty oil can contribute to tapping sounds. If the noise persists, further investigation into the bottom end or other internal components may be necessary.
