Bike Emitting Smoke? Fix It Fast to Avoid High Costs & Fines!
•Thick white or black smoke from your bike's silencer indicates engine problems, leading to increased fuel costs and potential fines up to ₹10,000 for not having a PUC certificate.
•Black smoke results from incomplete combustion (rich mixture), while white smoke indicates burning engine oil due to issues like piston rings or valve seals.
•Solutions include cleaning/replacing the air filter (₹150-₹300), cleaning/replacing the spark plug (₹100-₹150), and cleaning the carburetor or using a fuel injector cleaner.
•Regularly check and top up engine oil with the correct grade; avoid overfilling as it can cause white smoke.
•Maintain correct tire pressure weekly to improve mileage by 2-3 km/liter, and follow bonus tips like avoiding sudden acceleration and getting timely servicing.
