After the oil and valves have been taken care of, the remainder of the "service" deals with checking the torque on critical fasteners under the catch-all heading of "chassis bolts and nuts." Be sure to check the swingarm pivot (3), exhaust headers (4), pipe mounts and muffler bolts. If your bike has motor mounts like this (5), just check the torque on the center fastener. The secondary fastener, for which you'll need a special tool, is used to align the engine to the frame; unless there's a visible gap between this shim and the engine/frame just leave it alone. Continue system-by-system through the bike, checking the hardware on the steering, brakes (6), axles and pinch bolts, driveline (7), footpeg and handlebar mounts, and so on.
