Continuing with the rear section: let’s perform maintenance on the swingarm and linkage areas.
For Suzuki bikes, removal takes 30 minutes. Bearing extraction takes another 30 minutes. After that, nearly three hours—cleaning and reassembly are time-consuming.
The oil is well-applied, so we can feel confident.
The sleeve shows no major damage and is in good condition.
The presence or absence of oil makes a huge difference in longevity. We’re constantly reminded of how important this is.
GSF parts are still available, but some pivot shafts are already discontinued. Don’t assume parts will always be in supply.
Chain buffer? The slider can only be replaced when the swingarm is removed, so it’s definitely a part we want to replace.
We clean everything and reassemble the bearings.
The image is of a 750RK, but the pivot configuration looks like this.
Since the swingarm fits inside, there’s naturally some play. We tighten the shaft and flex the frame to eliminate the play.
Some 1100M/N and newer pivots have adjustment built in. It’s a well-thought-out design.
We insert shims to adjust the width so the frame doesn’t bear unnecessary stress, achieving smooth movement with minimal play in all directions.
Whether to insert shims equally on both sides or favor one side, and how that affects the chain line—these are the kinds of decisions we wrestle with every time.
The GS1200SS and Inazuma 1200 are especially loose. When lifted, the swingarm rattles side to side. This looseness might be one reason water gets in and rust develops.
We also replace the wheel bearings and hub damper. The chain and sprocket have already been replaced.
The rear shock is a Nitron.
We also replaced the shift oil seal while we were at it.
