This manual was written by the Yamaha Motor

have a basic understanding of the mechanical con-
cepts and procedures inherent in snowmobile
repair. Without such knowledge, attempted repairs
or service to this model may render it unfit and/or

continually striving to improve all models manufac-
tured by Yamaha. Modifications and significant
changes in specifications or procedures will be for-
warded to all authorized Yamaha dealers and will,
where applicable, appear in future editions of this
manual.
