So I just had to replace the crankshaft on my 400ex. Took everything apart, replaced it, and put everything back together. Something isn’t right though:

-I cannot get the wheels to move no matter what I do
-If the clutch is in, it starts right up – if i let off the clutch it dies
-The back tires are locked, whether I have the clutch in or not – and I can’t find neutral
-It seems to me like I can shift down to first, and up to either neutral or second (can’t tell which because the tires are locked regardless), but occasionally the shifter is just stuck and I need to tap it several times to move.

Does anyone have any ideas what the issue might be? More specifically, could it be anything that won’t involve me taking the whole thing apart and splitting the case all over again? I’d like to try any possibilities before I tear it all down as that’s relatively time consuming

Thanks in advance!
