to final assembly. If performavce 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

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
warrany.
