INTRODUCTION
This chapter includes all information necessary to perform recommended checks and adjustments.
If followed, these preventive maintenance procedures will ensure more reliable vehicle operation, a
longer service life and reduce the need for costly overhaul work. This information applies to vehicles

should be familiar with this entire chapter.

PERIODIC MAINTENANCE CHART FOR THE EMISSION CONTROL SYSTEM
• The annual checks must be performed every year, except if a kilometer-based maintenance,
or for the UK, a mileage-based maintenance, is performed instead.
• From 50000 km (30000 mi), repeat the maintenance intervals starting from 10000 km (6000 mi).
• Items marked with an asterisk should be performed by a Yamaha dealer as they require special
tools, data and technical skills.
