My CG125 has completed 7 years, so far no trouble in engine, rings, piston, valves.
Just changed the chain and sprocket set after completing 52,000kms. Bike engine was making some loud noise from clutch side since last 2 months. Yesterday went to mechaninc and came to know that the primary gear drive is worn out.
Changed the drive today, local drive was available for 550/ in silver but purchased imported which cost 780/ and the color was carbon black.
