I've had the Z1 kit for several years now. It is an annoyance (though easy) to adjust and it's not made with quality parts. I've had to replace the cylinder about every 12-15K miles (over 50K miles on the kit). I thought I might be doing something wrong, but I still experienced the same failure rate even after having Austin Z Clinic replace it for me.
