Smile Engine whine

Hi
I have a 2003 749 done 26000kms. It had the full service at 21000kms. It has recently developed a quite audible whine though the low rev range. It disappears around the 3900 revs and runs sweetly after that. Has anybody got any advice or has anybody come across this with their machine. I have stopped riding it until I can get it sorted

The belts were changed 5000kms ago. I have just found the receipt for the work that was done and the belts were changed but not any of the bearings. I will follow it up with the Ducati people here. Thanks so much for your reply

a co00oing sound is very likely a slightly tight belt not sure what bearings would sound like... this is very common with Aftermarket belts... OEM will have Ducati written on them. Make sure you weren't charged for OEM and given something else.

thanks for your input. They are definitely Ducati belts. The only issue I have is that the belt change and service was not done by a Ducati tech. I have since had a well respected Ducati mechanic look at it albeit briefly and he thought one of the belts may be a little tight but nothing life threatening. Its going in for a full checkup shortly. I haven't ridden it since the noise appeared so I'm starting to suffer a little bit of cabin fever

I have since changed the 4 belt tensioner bearings but the noise is still there. It does appear to be coming from the top of the vertical piston. Any thoughts on this. Cheers

I have been using non OEM belts and at times there is a sort of whine - coooooing - belts are adjusted properly but if Ducati belts then maybe they are tight.

I know this thread is a bit old but I was wondering if the problem was ever solved.

Why am I asking, you say?

I just took my 2003 749 out for it's first spring ride yesterday and I have a high pitch whine that varies with rpm and goes away at higher rpm.

Thanks.
