Hayabusa Clutch Bleeding problem
Hi All
After some advice with regards to my clutch. I've built a kit car with a busa engine in. I have a reservoir pot that serves both the brakes
and the clutch. The clutch master cylinder is actually the busa rear brake master cylinder from the bike. From here i have braided hose to the
engine slave cylinder.
My issue was i noticed the car creeping when in gear and my foot on the clutch. Straight away to me that means more than likely there's air in
the system, so set about bleeding the system again. This time im using a one way valve set up, you put it on the bleed nipple, release is and then
pump the pedal till all the air is out. Problem is the air keeps coming! spen about two hours on it and it still keeps coming. heres a link of the
tube after pumping the pedal a few times and stopping.
you tube vid of air
im not loosing fluid so there's no leaks, just can't see where all the air is coming from? any ideas.
Cheers in advance
Adam

Had a similar situation with a Rover 200. We could not bleed the brakes, despite several hours of trying. The solution in the end was to change the
Master Cylinder, which was new but faulty. What was happening was that on releasing the pedal air was being pulled in around the piston seal instead
of oil from the reservoir.

When using that sort of bleed pipe, it's best to close the bleed nipple for the pedal return on the last coule of presses as they do tend to
suck air in past the nipple threads.
Are you sure it's not over-throwing the clutch? That will cause drag. Have you tried not pushing the clutch all the way to the floor? It's
not uncommon on BUSA installs and a pedal stop is the answer.
