Resurface flywheel

Quick question.... Not to long ago I resurfaced my flywheel (800 miles) and now I plan on switching out to an Act HD clutch. Currently using a Clutch Masters 6 puck(sprung).
Can I just sand it down with an orbital sander? Or will it need to be removed to get resurfaced?
Clutch was used gently since I am breaking in the motor.

You don't need to do anything. Swap the clutch and go

Yep. Zero reason to mess with it.

Really I'm not a fan of resurfacing flywheels in general, but if you JUST had it done there's no reason.

I would just clean it up with brake cleaner and go. If you see marks or dark spots on it that's totally normal.

Thank you. I'll check it. Good to know it will only be a half a day job!

How is everything going? Just curious as I swapped out my clutch with an ACT HD and have a bit of chatter or a tiny bit of vibration that seems to be getting better as I go. This is swapping out a clutch from Pettit and the flywheel has maybe 12k miles on it now? Somewhere around there. I never thought to mess with the flywheel, but I am not sure wheat else it could be.

I remember many moons ago when I swapped in my sprung 6puk sprung clutch (ACT) with HD pressure plate. I experienced clutch vibration/chatter for the first time. It was not a nice experience and I thought something was wrong. However, over time it gradually got less and less until un-noticeable .

With 12k on the flywheel I would definitely resurface it. With the clutch I have now I'm changing it because I'm experiencing chattering on when going on reverse. I'm told that this is normal with a 6 Puck disk. Looking for more of an OEM driving experience..

Puck disc clutch I don’t know. But if the FW was new, and true to begin with, 12k miles should be next to nothing with a standard clutch disc (ACT HD, OEM etc) with adult street driving.
If it seems to be improving with use I might suspect minor contamination of the disc.

Thx. It is a standard disc. I should have reiterated that. It seems to be improving. Such ashame the shop delivered it like that. Why is it so damn hard to find good help these days?

Clutches, motors, brakes, exhaust parts, shifters sometimes, subwoofers apparently and some other things...... they all have a sort of break in time. From brand new they will do things, smell, sound and feel different for a little while after that initial install. As a shop, we inform our customers of this and assure them it's not a fault, its just new parts being new.

For a shop to do this break in process for the customer it would require extensive test driving. An amount of driving that is arguably outside the scope of "verifying repairs".

in this specific situation with the clutch, 9/10 times there is no noise or chatter with a new install. In the rare cases that there are, as mentioned it does go away. The important part is if a shop did the job (which the op did it himself) then they inform the customer of the situation and educate them on what's going on.

We've done A LOT of clutch jobs on various cars since we don't just do RX7s and only 1 has given us any kind of nonsense post install. A focus st we put a clutch masters stage whatever in had/has a light chatter to it. Its just a trait of that clutch but it does sound weird given that the chatter is inconsistent.

there are many examples and things to give but I figured I would address testruns statement. It's not necessarily about shady/poor work.
