hi all , i recently brought a sherco 290 04 model , bike is very clean and looks like its had hardly any use!! however ever since i have had it , its got a really annoying whine , sounds like its drive related .. last week i stripped the engine completely and replaced , mains , all gearbox bearings, rings , waterpump bearing and a few other things!! im a motorcycle mechanic by trade so i should know what im looking at lol!! all the gears look ok , selectors are good . however once all back together and running it still whines??? you can change the noise with the clutch!!! i have been told by a few people at my local trials place that all early shercos whine!!! surely this cant be true!! can anyone shed some light!!
cheers tony
