I just installed one of these (I haven't test ridden it yet, I'm replacing my exhaust at the same time and am waiting on it). A couple of comments based on my install: 1) The cylinder comes with piston very retracted. Even with pre-bleeding, it takes a LOT more fluid to move the piston to contact the clutch shaft. I actually removed the slave and pre-bled it again because I wasn't getting the pressure on the leaver. Once I realized how far back the piston was compared to the factory piston, I knew it would just take a lot more fluid. A vacuum bleeder won't push out the piston, so you have to pump the leaver. 2) The pickup on the master reservoir is pretty high up so it's easy to run the reservoir dry, which means you have to start all over again. 3) The tube you sent with mine was annoyingly small and it was pretty hard to get it on the bleeder. I couldn't do it by hand (as in the video), I had to use pliers to push it on and the tube tore in my first attempt.
Your written tool list has one hex driver, the photo shows two different size hex drivers. Additionally the hose clamps on the heat shields must be loosened, maybe add a 5/16 socket for a 1/4 inch drive for that. Much easier than a flat blade screw driver... Plan on installing one of these soon so I checked it in detail..
What would it mean if after installation the pull is reduced significantly but then after some time requires more effort, almost back to the level required to pull in the clutch with the stock slave cylinder?
