devices and systems may be performed by any repair
establishment or individual; however, warranty repairs
must be performed by a dealer or service center authorized
by Maruyama Manufacturing Company, Inc. The use of
parts that are not equivalent in performance and durability
to authorized parts may impair the effectiveness of the
emission control system and may have a bearing on the
outcome of a warranty claim.
Maintenance on today's low-emission engines is
even more critical for longest life and best performance.
particularly critical are air and fuel filters,
spark plug heat range, cooling air intake area and
proper gaps of coil and plug.
