I've had mine for over 10k miles same thing in neutral i hear noise push the clutch in goes away. Been like that from the start, but i don't know what exact noise your hearing. My Mclead is not like stock quiet because it's twin disc. I'm putting about 800 rwhp and i get that wwwrrrrrhhh nosie which dissapointed me because i changed to this from center force which was horrible. GL

Neutral 'can of marbles' sound is normal with a twin disk clutch--it'll be even more exacerbated if you have solid mounts.
I have a Mantic twin and Hinson mounts in my car and if you didn't know better, you'd swear something was wrong with it. I love how the mounts feel though--the whole car feels stronger and its hard to describe on paper, but its like everything feels more connected-more visceral.
Do you have a lightweight aluminum flywheel? If so, the dampening provided by the heavier steel unit is gone and you'll hear/feel all the rattles/marbles in the drivetrain.

Just curious, OP. You said that you just installed a new driveline. Are you sure you want to go out and pound on it WOT right away? I would drive it a bit first on a new rear end and let the clutch seat and get some heat cycles for a 500+miles.

Mine does the exact same thing with the noise in nuetral with the clutch out and goes away when I push the clutch in. I have about 220 miles on mine now as I just did the swap several weeks ago. The clutch is noticably smoother now that it was 200 miles ago. I am happy with the swap thus far.

Put it this way--I thought the sound was bad enough after I installed the mantic twin disk clutch that I couldn't sleep. I thought for sure the slave cylinder wasn't bolted up or something. I ended up towing the car to my buddys shop and pulled the drivetrain out again, only to find out that everything was 100% and the noise is just normal.
My buddy calls it the 'death rattle' because it sounds like the car is going to die.

I hardly notice the "can of marbles" sound on mine unless I listen closely. The junk monster level 5 that came out was WORSE, and it was a single disk. I warrantied that one out just to get the same result on the 2nd one.

Between the 750 idle speed, aluminum flywheel, and solid mounts, the sound is pretty loud. I upped the idle to 900 and it's not quite as bad now but it is still present. I love everything else about the clutch so I'm happy to make the one compromise.
