Here's a little follow up to my resent issues with the z-start. I was unfortunate to have got one of the z-starts that came with only two clutch cover gaskets ('04 YZ 450 issue only). What I didn't pay attention to when I was checking the installed gap after the first few rides was that the throw out and the pressure plate were hitting the clutch cover. Well, bad went to worse and I smoked a set of clutches. Another thing I noticed all along was that the actuator arm never moved when the bike was revved/ridden. Shame on me for not asking but surprise, it's supposed to move 30 to 40 degrees. Even though I'm out a hundred bucks for a new clutch pack I still enjoy the benefits of having the z-start and think it's going to be worth it in the long run. Al and the others at Rekluse were very patient with me when I probably wasn't so understanding. Al footed the bill for me to send my z-start to and from his place to personally check everything out. Turns out that everything checked out ok with all the internal pieces except for the throw out. They've removed .050 from the end of the throw out to assure it doesn't rub the cover. I installed it again tonight with new friction and drive plates, three gaskets and the new throw out. It now works perfect! Actuator arm and all.
