What warranty do your engines have?
Major components are covered for 1 year from the date the warranty is activated: breakage of the camshaft, crankshaft, connecting rod or valve not caused by external force, and sand defects in the cylinder block or cylinder head.
What is not covered by the warranty?
Head gasket damage from overheating caused by inferior antifreeze, tap water or cooling-system faults; abnormal wear from inferior oil or oil filters; oil consumption from inferior air filters or dirty intake air; and failures from improper installation or improper use. Indirect losses are not covered.
What should we do if an engine fails during the warranty?
Contact our after-sales technical support before opening the engine, and send the engine number, photos, videos and maintenance records. Disassembly needs our authorization; covered faults are repaired or the faulty components replaced free of charge.
Installation & First Use
From the operating manual supplied with our engines.
How should a new engine be run in?
During roughly the first 1,000–2,000 km, before the first service, generally keep below 70% of rated engine speed and avoid sudden acceleration and long full-load driving. After a cold start, idle 1–3 minutes before driving.
When is the first service for a new engine?
At 500–1,000 km, changing the engine oil and the oil filter. After that, every 5,000 km with oil, oil filter and air filter. Keep the service records for warranty.
