HOW TO USE THIS MANUAL
This manual is intended as a handy, easy-to-read reference book for the mechanic. Comprehensive explanations of all installation, removal, disassembly, assembly, repair and check
procedures are laid out with the individual steps in sequential order.
1
The manual is divided into chapters. An abbreviation and symbol in the upper right corner
of each page indicate the current chapter.
Refer to “SYMBOLS”.
2
Each chapter is divided into sections. The current section title is shown at the top of each
page, except in Chapter 3 (“PERIODIC CHECKS AND ADJUSTMENTS”), where the sub-section title(-s) appears.
3
Sub-section titles appear in smaller print than the section title.
4
To help identify parts and clarify procedure steps, there are exploded diagrams at the start
of each removal and disassembly section.
5
Numbers are given in the order of the jobs in the exploded diagram. A circled number indicates a disassembly step.
6
Symbols indicate parts to be lubricated or replaced.
Refer to “SYMBOLS”.
7
A job instruction chart accompanies the exploded diagram, providing the order of jobs,
names of parts, notes in jobs, etc.
8
Jobs requiring more information (such as special tools and technical data) are described
sequentially.

IMPORTANT INFORMATION
PREPARATION FOR REMOVAL AND
DISASSEMBLY
1.Before removal and disassembly,
remove all dirt, mud, dust, and foreign
material.
2.Use only the proper tools and cleaning
equipment.
Refer to “SPECIAL TOOLS”.
3.When disassembling, always keep
mated parts together. This includes
gears, cylinders, pistons and other parts
that have been “mated” through normal
wear. Mated parts must always be
reused or replaced as an assembly.
INFO
4.During disassembly, clean all of the
parts and place them in trays in the
order of disassembly. This will speed up
assembly and allow for the correct
installation of all parts.
5.Keep all parts away from any source of
fire.
EB102010
REPLACEMENT PARTS
Use only genuine Yamaha parts for all
replacements. Use oil and grease recommended by Yamaha for all lubrication jobs.
Other brands may be similar in function
and appearance, but inferior in quality.
EB102020
GASKETS, OIL SEALS AND O-RINGS
1.When overhauling the engine, replace
all gaskets, seals, and O-rings. All gasket
surfaces, oil seal lips, and O-rings must
be cleaned.
2.During reassembly, properly oil all mating parts and bearings and lubricate the
oil seal lips with grease.

IMPORTANT INFORMATION
USING A DYNAMOMETER
The YZF-R1 has a carbon muffler that may
change color when exposed to high temperatures. Therefore, when using a dynamometer always use a fan to cool the
muffler.

BEARINGS AND OIL SEALS
1.Install bearings and oil seals so that the
manufacturer’s marks or numbers are
visible. When installing oil seals, lubricate the oil seal lips with a light coat of
lithium soap base grease. Oil bearings
liberally when installing, if appropriate.
