Whining noise on cold start

Hey all,

2013 Frs 78k miles.
Replaced belt a few months ago after a slight squeak I was having. Seemed to solve that issue.
But now on cold starts I have another weird sound. Seems to go away after a few minutes. Basically after the high rev warmup and then the noise goes away. Doesn’t matter if the clutch peddle is pressed or not.
No issues changing gears.
No slipping
My fork does squeak a bit but has for over a year.
I have a new clutch ready to go in but just have not installed yet.
The car runs and drive great.
If anyone has any suggestion on what this noise could be I’d be happy to listen.
I am not sure if this could be the TOB and a input shaft. I’ve heard they can make these sounds at times but I am not very knowledgeable on clutch and transmission issues.
Also thinking it could be a pulley. But I can’t pinpoint where the sound is coming from when I pop the hood.

Thanks. Please be gentle ��
