Hi, on my 2002 RT I've been noticing a noise that comes and goes for a couple thousand miles.
The first time I heard it was on a long trip so I became very concerned but then the noise seemed to dissipate and then return after the bike has been ridden an hour or more.
The noise follows the engine speed, sounds like a SSSHH, as if a piece of metal is laying on a turning part. My guess is an alternator bearing or some accessory drive bearing starting to poke out it's ugly little head, but the noise is subtle and I was waiting for it to get worse or for something to break.
It's been the same for a couple months, but now I need to store the bike and if it needs to be torn apart I would like to diagnose it before winter so I know where I'm headed with it. I may pull the front cover and see if I can locate the noise with a stethoscope. Looking for advice by some oilhead gurus
.
thanks in advance
Bob
