put it on the center stand, fire the bike up, put it in gear and listen to it. helps to pull the trans fill cap as well. *may spray fluid though. might be more clear as to where its coming from.

Is that noise happening only as the clutch is slipping as you take off and then goes away once the clutch is engaged?

ok.

like said, might be a bearing. if the trans fluid is fine, my guess would be that, if a bearing, the one behind the clutch if its not going away w correct fluid level. Had an H1 that grenaded one on the way into work one day, and I could hear the teeth backlash get off and howl when it was moving around and whine like that, made way more of a racket though.  could be 1st gear. who knows.

I, at my day job, am an industrial safety dickhead. Don't screw around with silica. A simple 3m respirator with P100 filters and a good fit will literally preserve your quality of life. Walking around with a bottle of oxygen is not that much fun, and I know people that now do that because of silica exposure that wasn't controlled. A lot of people treat me like I'm a turd, but I just want people to enjoy the things they enjoy. Work more often than not isn't what people enjoy, and when you are building motorcycles for fun it certainly is not worth hurting yourself irreparably.

I am a novice at these bike.

I had just filed up the tranny with same fluid as in the RD's.

When using glass (perhaps vapor honing an exception), please guard your breathing. Inhaled glass dust can lacerate the linings of sinus and lungs, leaving them open for infections. I suffered regular sinus infections and bouts of pneumonia until we stopped using glass beads at work and switched to fine aluminum oxide.
