Hi, I'm looking at buying a gsxr1000 and was looking at a 2002 model (with around 10000 kms). It was basically in brand new condition. When the engine was started there was a bit of a sound which I will try to describe : It was a whirring or squeaking sort of sound (maybe sort of like something you might hear if a water pump bearing or something was wearing out.).It didnt sound terminal & wasn't a grinding sound as if something was about to fail or anything. It varied with the idle speed of the engine so I guess it could have been something in the valvetrain or else something that runs off the engine such as the alternator or water pump etc. It seemed to come and go a little bit though that was probably just as the idle hunted a bit while the engine was cold. It quietened down as the motor warmed up and basically blended with normal engine noise after a couple of minutes. Apart from this the motor sounded healthy, no smoke or anything and didnt have any rattles or hesitation when blipping the throttle or anything. The problem is I've no experience with newer type bikes like this so I don't know if its a normal sort of sound on a cold engine for this bike or something I should be worried about. Any advice anyone can give me about this sound or anything else to look for on these bikes would be greatly appreciated. Thanks !
