Looks like those lines made a big improvement 😊. I have a similar vacuum bleeder and found the same as you. The nipple attachments are too big for bike bleed nipples. I think they're meant for cars. I don't think you need to touch the lever, just pump it to create a vacuum, then open the bleed nipple. I found air can get pulled through the brake nipple thread if you open it too much. Most of the time, I just resort to the old method. It's also worth getting a large ish syringe. You can reverse bleed with it if you're having difficulty getting the fluid through. I also suck the fluid from the reservoir using a syringe before starting the drain down or when renewing fluid. I have old Goodrich lines on my vfr750 fitted by a previous owner, if they don't have plastic coating, make sure they can't touch the paintwork, mine were rubbing so I removed them and fitted heat shrink.
Can you make a video of how it feels once the lines have been replaced? I know these Zx10's are notorious for being fast getting up to speed, but not so much slowing back down. I'm planning on swapping my lines for stainless as well, and would like input on whether it is a crazy difference or not.
The travel is reduced and feels firm with new lines, so would expect braking to feel more confident. I'll do a riding video when I can, I never found the brakes to be bad. Just had a spongy feeling, with lever at max travel......which could be dangerous 🤔🏍

Hi thanks for watching the channel.
Reverse bleeding is a good shout, did that on the ZX10 clutch 👍
