When you replaced your clutch shoes, did you also replace the spring?
If you did replace the spring, did you hook the ends together and then slip the spring over the shoes or did you wrap the spring around the shoes and then hook the ends together? Sounds silly but it can make a difference with the 09 clutch.
"go in and out"? You mean the clutch engages intermittently?
Which part sounds like a box of rocks?
Something that also came to mind, check the gap between your clutchbell and flywheel. Also, make sure the ends of your clutch spring are at the center of one of the shoes and not at the gap between them.
