Seemed my '99 RSV whine was getting louder

[YamahaLarry]

I may just be paranoid after pretty much reassembling the entire bike after a repaint and noticing things a little closer. But it seemed the past week or so the whine in my drive train was much more noticeable. I run Rotella T6 with Motorkote and go 5k to 6k miles on oil changes. Had a little over 5200 since last change, so I did oil change today of motor oil and final drive oil.

 

Took it for a short drive and it seemed quieter. Has anyone experienced it silencing some after an oil change, using same oil as usual?

 

Like I said, I have been a little paranoid, especially after having some screws left over after reassembly.
