Engine/clutch Whistle whining noise

Hi all. I just baught myself a great looking ZX10 - 2009 model with 27000 km on the ODO. After a ride or two i picked up two issues. One was easy fix. Side stand switch issue where at 10k rpm she lost power badly. Second one now is a weird whining whistling noise. This only happens when i pull in the clutch. Any ideas where to start. It has to be something on the clutch basket or plates or something. Any advice on what to do. Dont really want to take it to a dealership.
