When I did the seventh gear mod and pulled off the slave the piston didn't move out of it's bore. I took it off the line, washed it in hot soapy water, cleaned everything in more hot soapy water then did a couple of rinses in more hot water.
Dried everything with a warm air gun then reasembled using Raybestoes Silicone Brake Grease on the seals and piston. After that I had to use a band to keep the piston in as the internal spring wanted to push the piston out. Much smoother clutch action now and less lever pressure.
So how do you define success.....
