Suzuki GSX-R 1000 Service Manual: Drive chain inspection and adjustment
Inspect drive chain
initially at 1 000 km (600 miles, 2 months) and every
6 000 km (4 000 miles, 12 months) thereafter
Drive chain visual check
- With the transmission in neutral, support the
motorcycle using a jack and turn the rear wheel
slowly by hand.
- Visually check the drive chain for the possible defects listed as
follows. If any defects are found, the drive chain must be replaced. Refer
to “drive chain replacement” in section 3a .
- Loose pins
- damaged rollers
- dry or rusted links
- kinked or binding links
- excessive wear
- improper chain adjustment
- missing o-ring seals
Note
when replacing the drive chain, replace the
drive chain and sprockets as a set. |

Drive chain length inspection
- Loosen the axle nut (1).
- Loosen the left and right chain adjuster lock-nuts (2).
- Give tension to the drive chain fully by turning both
chain adjuster bolts (3).

- Count out 21 pins (20 pitches) on the chain and
measure the distance between the two points. If the
distance exceeds the service limit, the chain must be
replaced.
Drive chain 20-pitch length
service limit: 319.4 Mm (12.57 In)

- After finishing the drive chain length inspection,
adjust the drive chain slack.
Drive chain slack adjustment
- Support the motorcycle with a jack.
- Loosen the axle nut (1).
- Loosen the left and right chain adjuster lock-nuts (2).
- Loosen or tighten both chain adjuster bolts (3) until
there is 20 – 30 mm (0.8 – 1.2 In) of slack “a” at the
middle of the chain between the engine and rear
sprockets as shown in the figure.
Caution
the reference marks “a” on both sides of the
swingarm and the edge of each chain
adjuster must be aligned to ensure that the
front and rear wheels are correctly aligned. |
Drive chain slack “a”
standard: 20 – 30 mm (0.8 – 1.2 In)


- After adjusting the drive chain, tighten the axle nut
(1) to the specified torque.
Tightening torque
rear axle nut: 100 n·m (10.0 Kgf-m, 72.5 Lbf-ft)
- Tighten both chain adjuster lock-nuts (2) securely.
- Recheck the drive chain slack after tightening the
axle nut.

Air bleeding from brake fluid circuit
Air trapped in the brake fluid circuit acts like a cushion to
absorb a large proportion of the pressure developed by
the master cylinder and thus interferes with the full
braking performance of the brake caliper. The presence
of air is indicated by “sponginess” of the brake lever and
also by la ...
