just curious, when bike is on stand and running, you pull in clutch and put trans in first gear while still holding cluch in (so technically still in neutral) should the rear tire spin or no?

mine is spinning which surprised me because it is neutral. is this just how bike trannies work?

How fast is it spinning? Usually mine will spin ever so slightly. But it's such a weak spin that you could stop it by poking it with your finger nail.

Mine spins lightly when on the rear stand and in neutral.

Mine did that, with more force than I could stop with a finger nail.
I adjusted the free play at the lever and it became finger-nail-stoppable.
If there is an aftermarket adjustable lever, it might be too close
to the bars to fully disengage....

Not sure, but a wet clutch bike might be spinning more?

This is normal.  As long as you can find neutral easy, oil warm if it is a wet clutch all is good.  DO NOT adjust the free play unless you have too much (more than 2 mm.).  Yes, the oil in a wet clutch will transmit power, particularly when cold.

Dry clutches will too.  There is always enough touching inside the clutch to spin the rear wheel while in gear with the engine running and the tire raised off of the ground.  But you should be able to stop the spinning by just touching the tire.  I've been known to occasionally spray chain lube on under such circumstances, since it's not all jerky like if the clutch is out.  "Don't try this at home."
