GSX1100SR inspection with fork oil change, stem lubrication, and other maintenance services.
The customer asked about doing a full overhaul on the forks and stem, but since the bike hasn’t racked up that many miles, it would be wasteful. So we went with fork oil change and stem lubrication instead.
The fork oil was clean. We filled it with Newtech synthetic fork oil in the original spec set.
We cycled the forks, pulled a vacuum, and then adjusted the oil level.
We checked how the original tuning felt, whether anything had loosened up, and so on before disassembling.
There was some grease loss, but the condition was good overall.
Inside the pipes and around the oil cooler, there’s surprisingly a lot of oily grease buildup. A thorough cleaning makes everything feel better.
We used Newtech NC100 grease, which is a bit softer than the spec and works smoothly. Even when the frame gets hot, it doesn’t drip easily, which means better bearing life.
The oil cooler core guard was vibrating quite a bit, and when we looked closely, it was cracked. The mounting points seem a bit weak.
We wondered if maybe just this bracket was sold separately, but replacing it wouldn’t solve the problem anyway, so we came up with a fix.
Removing the rivets at the base is a bit tedious, so we reinforced it with a patch and spot welding instead.
We have our shop equipment set up for situations like this. For custom work, please visit a custom shop.
We cleaned and lubricated the speedometer cable and gears. Friction might have dropped by 0.01 percent or so.
The axle shaft is in good shape.
The wheel bearings look good. Recommended replacement interval is around 20,000 to 30,000 kilometers.
We cleaned all three calipers, lubricated them, and applied rust preventative.
We cleaned, lubricated, and adjusted the chain.
The fluid was clean. We replaced it with Golden Cruiser DOT4.
We applied thread compound generously to the exhaust pipe bolts and replaced them with new ones.
The original plug is a DR8EA, but we switched to a JR8B, which has the same dimensions and function and is used in oil-cooled models.
We synchronized the carburetors.
We cleaned the brake discs and then applied the brakes firmly to seat them properly.
We replaced all the exterior grommets.
That’s all for this service.
