Why is my KAYO MOTOR K4 Motorcycle exhaust producing black smoke?
- A
  Angelica CarrAug 7, 2025
  If your KAYO MOTOR Motorcycle exhaust is producing black smoke, several factors could be the cause. It might be due to worn valve guides, which would require replacing them. Alternatively, a leaking or damaged oil baffle could be the culprit, necessitating repair or replacement. A leaking cylinder head gasket can also cause this issue, and replacing the gasket would be the solution. Finally, excessive piston ring clearance could be responsible, in which case adjusting or replacing the piston rings is advised.

  Dr. Amanda GainesAug 16, 2025
  If your KAYO MOTOR Motorcycle has excessive or abnormal noise, it could be due to several reasons. You may have incorrect valve adjustment, in which case you should adjust the valves correctly. Another reason may be that the valve is stuck or the valve spring is broken, in which case you should free the stuck valve or replace the broken valve spring. Also, the upper rocker arm may be excessively worn, in which case you should replace the excessively worn upper rocker arm. Inaccurate gas timing or camshaft wear may also be the cause, so you may need to set the gas timing accurately or replace the worn camshaft.
