What are the chances bleeding and/or replacing the clutch slave would fix it?

Not likely to help but easy enough to try. You may be able to adjust it out as was mentioned.

I have an ACT as well Pat, same exact problem. I just leave it on because it is not a street car anymore, and it does not bother me while on track, but it does feel like clutch drag to me. I also had it with another clutch, but with OEM flywheel, so it is not related to the flywheel only, but probably a combination of clutch and flywheel depth and the adjustment on the pedal travel. I saw a post somewhere to fix it but I never got around to it.

Edit: also, for what its worth. I did bled the clutch MC completely and it did not help.

I definitely put a little bit of Moly Paste (https://www.hondapartsdirect.com/oem...%3D&origin=pla) on the shaft.. I'm still running stock clutch, but do have a lightweight flywheel.

According to the manual, there shouldn't be any grease applied where the TOB travels.. Do you think it's to keep the shaft from getting gunked up in that location?

Well I can't say for sure it was because of the grease (whether there was too much or too little).

The OE TOB actually comes pre-greased on the inner race surface, where it sits on the input shaft cover.

When I installed the ACT kit, I put a very light coat of the hi temp grease (that came with the ACT clutch kit) on the splines, TOB inner race, on the input shaft cover where the TOB sits. All of this is per recommendation/common practice. If the clutch disk had problems coming away from the pressure plate, may be due to lubrication issues. Might not be the root cause, but is worth a consideration.

The Factory TOB comes pre-greased where it sits on the input shaft/cover. I put a light coat of the lithium grease that came with the ACT kit on the splines and on the shaft/cover. If the clutch disk had problems coming away from the pressure plate, may be due to lubrication issues. Just a consideration.

Do you know if the guy you sold the clutch to used grease or not?

Knowing the guy I sold it to, he probably did the bare minimum and didn't take much care in the process.

Nothing like OEM lol

I bled the clutch with fika84's help and it did not make a difference. I have an appointment with the shop that installed the clutch to see what they think.

The shop that installed the ACT kit removed it and installed an OEM kit and yet ANOTHER redesigned OEM TOB. They said the most recent update to the TOB is very different than every other one. While I'm bummed to lose the benefits of the LWFW, it's nice to be able to drive my car on the street without issues. They said the ACT clutch, flywheel, and pressure plate are fine and were not the issue.
So yeah....who wants to buy an ACT kit with just a few thousand miles on it? The shop said it is in nearly new condition as expected given the mileage.
