Finished re-assembling a 400E that I was rebuilding for a class. I got the engine back in the bike and *then* tried out the shifter. (Lesson learned, check shifting before putting the engine back in the bike.) Couldn't shift at all. It felt frozen. So... took of the clutch cover and side cover, clutch assembly, and realized the pawl lifter wasn't seated correctly. Took that out again and aligned correctly, put it back in, then the gear shifting arm, clutch assembly, and covers. Cool. Now with the shifter peddle in place, tried it out again. I can shift up and down. But... it doesn't stop either up nor down. Meaning, I can go down as much as I want. This doesn't seem right What did I do that I need to do?
