Hi, I'm new to the Z400, just picked up a 2004. My problem is when I down shift looking for first gear it will go all the way down into reverse without turning the knob. I checked the cable and it is not adjusted too tight. I removed the cable completely at the shaft going into the engine and pushed the shaft all the way in by hand and it still drops into reverse. All the way in should lock it out right? I have a Clymer manual but it doesn't offer much help for this issue. Anyone have experience with this issue? Thanks.
