squeaky noise suzuki df250 - need some help pls

Guys,
I have a question for my Suzy DF250 :
when idling after using the engine for some time i hear a light squeeking noise, much like a cambelt slipping. at revs above idle the sound is gone. what can this noise be?

1. this is a chain timed engine - so it cannot be a cambelt
2. it seems that when it has rained or at a day with high humidity it is more evident.
3. there were no rodents found in or around the engine

Have spoken to a local suzuki shop who advised that 'it is nothing serious' however still would like to know what it is (and indeed KNOW it isnt serious for sure)

any thoughts?

No idea I'm afraid. Is it definitely the engine or could it be the rubber mounts squeaking due to vibration at idle?

I had exactly the same thing on an Evinrude Ficht engine, was told 'nothing to worry about' next time I went out it ate its own piston rings! After the event the consensus seemed to be that the oil injector had failed on that cylinder.

Is the engine very old? Or done many hours? Or even still in warranty ?

I'd be concerned if it was mine!

Make sure you let us know when you do find out what it is!!!

Where does the noise originate?

F115's had a similar problem, caused by a bushing around the driveshaft in the upper leg. A heavy dose of lubricant down the shaft takes care of it for a while, though the "official" fix is to replace the bushing with one having a slightly larger bore (needless to say, I use the lube remedy.)

Take it back. Even if it's trivial, it's not per design and thus should be taken care of.
