   • Unscrew the cylinder head bolts with a socket wrench and carefully remove the head.

3. Remove the Piston:

   • Take out the circlips securing the piston pin and gently pull out the piston pin using a piston pin puller if necessary.
   • Remove the piston from the connecting rod.

4. Replace the Piston Rings:

   • Remove the old piston rings from the piston using a ring expander or by gently prying them off.
   • Clean the piston grooves with a clean rag.
   • New piston rings should be installed carefully. Align the gaps in the rings so they do not overlap, following any specific instructions provided with your piston rings.

5. Reinstall the Piston:

   • Apply a thin layer of engine oil to the new piston rings for lubrication.
   • Insert the piston back into the cylinder and secure it using the piston pin.
   • Replace the circlips to secure the piston pin in place.

6. Reassemble the Engine:

   • Carefully put the cylinder head back onto the cylinder block.
   • Tighten the cylinder head bolts to the proper torque specifications using a torque wrench.

7. Reattach Removed Components:

   • Reconnect any components that were removed, such as the carburetor and air filter.
   • Reinstall the battery.

8. Final Checks:

   • Make sure all tools are removed from the engine area.
   • Check for any oil leaks or loose connections before starting the engine.

9. Start the Engine:

   • Start the motorcycle and let it warm up.
   • Check the performance and listen for any unusual noises.
