WARRANTY
Strict quality control is implemented by our factory in all phases,
from parts manufactiring to final assembly.
If performance deteriorates or a part fails within one year of purchase
due to a manufacturing error,YS will repair or replace the engine at no
charge. Warranty will not cover normal wear.
Should the engine be modified, incorrectly assembled or abused,
there will be a normal charge for parts and labor. The use of four
cycle fuel due to low oil content will also void warranty.
