Ok, so I reclcoked my zforce500 to C1. In order to put the key in I had to compress the spring so tight that it took two guys to get it to the right spot and my wife put the key in for us. What I failed to do after that is any additional clocking of the helix. I didn't look to see where they were coming down on the black nylon ramps at all. I installed everything and took it for a spin and everything seams fine, smoother clutch engagement, etc. Should I bother with opening it back up to make sure the helix is sitting on the black nylon bumpers? Is this now a ticking time bomb or run it since it seams to be shifting fine? I'm sorry for all the noob posts, I am definitely learning a bunch on these machines! Feel like I really Sh$% the bed one this one!
