Clutch noise!

Check your clutch slave cylinder.

+1
If it didn't do it before, the slave is probably the cause
Have you ever fused the flywheel to the clutch?
Could be debris that needs to be worn down.
Just drive it, unless the clutch is slipping who cares about the noise
At the end of the day it's got 3,000 parts on it, somewhere down the line something is gonna rattle, creek or make noise.

Yah the noise went away after being driven out of storage, and clutch is not slipping!

When I installed in os giken twin plate clutch I had the same problem, I thought I installed it wrong, but after some research, found an answer as to why it rings when the pedal is engaged.

" Why do all OS Giken clutches make a noise when the clutch is disengaged?
All OS clutch kits utilize a free-floating pressure plate design. Most “traditional” clutch designs secure the pressure plate to the cover through the use of a pressure plate drive strap (aka “granny strap”). The advantage of having the granny strap is that clutch operation remains noiseless whether the clutch is engaged or disengaged. However, in many situations where the clutch is being abused (i.e. “spirited” driving and/or racing), the granny strap can become a weak point in the system and has a tendency to bend or break, potentially causing clutch failure and damage to drivetrain components. With the OS free-floating pressure plate design, pressure applied to the disks is even throughout the clutch lifespan, and the friction material of the metallic disks is bonded through a specialized process (as opposed to the cheaper riveted process used by most other competitors and OEM). This aids in increasing durability and lengthening the useful service life of an OS clutch, as power will continue to be transmitted effectively until the disks are extremely thin (since no rivets are present to create another weak point). Some race teams have gone through multiple seasons on an OS clutch before requiring a rebuild!

In regards to multi-plate clutch designs, all aftermarket manufacturers' multi-plate clutches will inherently emit a noise when the clutch is disengaged. This noise is emitted from the centerplate(s) vibrating against the cover posts. However, many competitors' clutches do not utilize the same strengthening processes during manufacturing as OS Giken, which will lead to increased material degradation over time. Because of this, the clutch noise will often become louder over time, as the centerplate(s) start to wear away and have more free-play within the housing. The OS design, coupled with the use of the most suitable materials and manufacturing processes, will minimize any system degradation and help to keep the clutch performing and sounding the same as when it was first installed. In fact, many OS Giken clutch users are proud to point out the signature noise emitted to anyone who asks, as it is a reminder that the car is equipped with one of the best performing and longest lasting clutches available!"

Yah as of now I don't bother with the noise so far!
