Already did the rear bearings and replaced what was left (not much!) of the ancient stock muffler (Its a '97 TRX300FW). The old girl also got 4 new tires, a spark plug, her fluids changed and i got her tuned up (will most likely receive a carb kit as well) and the clutch and throttle adjusted. After i overhaul the brakes she should run another 20 years easy...
