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
|
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.
