How To Avoid Costly Repairs
Your Honda engine can be the most expensive
component to repair. Proper maintenance,
especially the use of the recommended fluids
and filters, prevents premature wear and
damage.
Frequent causes of costly engine repairs are:
• Engine oil -- insufficient quantity, improper
oil.
• Air cleaner -- dirty, cleaned but not oiled,
leaking because of improper installation
(poor seal).

• Chain -- A loosely adjusted chain or a chain
stretched because of lack of lubrication may
come off and damage an engine case or
