Motive adapter for Clutch
My Z06 is in the shop getting a clutch upgrade with a remote bleeder. I would like to get the correct adapter to fit on the clutch reservoir so i can bleed it when i bleed my brakes. Does anyone know whats the correct adapter? I tried the existing cap on my friends C6 Z06 if its the same as the C6 the clutch cap is smaller.

I don't really understand what you are trying to do with the cap. If you are installing a remote bleeder you bleed from that line. Are you looking for an adapter so that a fluid bottle can attach to the top of the reservoir so it doesn't run low like a brake system? If so, that isn't needed in this case because the remote line should run up to the clutch master and typically you can monitor the level relatively easily. I usually fill the system and put the end of the bleeder line in the reservoir and pump the pedal a few times with the bleeder open. Then I check the level and repeat a couple of times. You will need a second person so that on the final time you or someone else is holding the clutch pedal down so that the line can be removed and the bleeder screw tightened. Then you can pump the pedal and should have good pressure if bleed properly.

I don’t recall seeing an adapter that small but hopefully someone chimes in.
I had a remote bleeder on my C6 GS. I used to use my MityVac with it. There’s so little fluid in the clutch system that it’s quick to do. Given the size of the fluid reservoir, I think using the Motive would be a pain since you have to take the adapter off to fill the reservoir. With the MityVac you can leave the cap off and quickly fill while you bleed.

It sounds like you are bleeding your brakes with brake fluid in the Motive Reservoir. Most of us just use the Motive to pressurize the hydraulic system and remove it to add fluid. That wastes a lot less brake fluid. It also means you don't have to clean out the Motive Reservoir after each use.

Yeah I still do & yes I do bleed with fluid. its just easier for me. I tried the vacuum approach & for me it didn't work as well. reason being is because the mighty vac sucks in air from around the swivel nut unlike when its in a brake caliper it does a better job.

I put a high pressure instrument valve in the end if the remote bleed line along with a hose barb. Then I use a Mity-Vac to pull a acumen. Open the valve and keep pouring fresh fluid in the reservoir until the fluid is clear. Very efficient and easy
The valves are cheap and you just need one for 600 psi The valves come with 1/8 or 1/4 pipe threads. Then you need a 3AN-pipe thread fitting (not aluminum) and a hose barb
