2001 400ex couple issues help

Hi everyone, I decided to rebuild my 400ex (since engine had seized on me) I decided to do it myself to save money and also learn since I have always wanted to learn. It took me a while but I finally got the engine rebuilt and decided to mount and try to start it before I put more money into it (also to know if I did it right). This is where the problem start first I’m not getting any spark I removed all tape and plastic wrap from wiring harness to make sure all connections are good and no wire is cut or anything. That checked out good, also I jumped started it and it does start that’s way but that is where the second issue appeared I noticed the clutch wasn’t disengaging so I couldn’t keep the four wheeler running. My question is what would cause it not to disengage. I replaced clutch disc and springs when I rebuilt and I reopened the right side of the crank case to double and triple check that I put everything on right. Thanks in advance for any help

07 Honda 420trx Rancher won’t shift

I have a 07 Honda 420trx rancher. We have replaced the electronic shift motor and the angle sensor. It will not shift at all. It doesn’t even try. Does not click or make any noise at all. What other options do I have? Can manually shift but hard to do. After replacing the shift motor and angle sensor it stopped throwing codes but still will not shift… any ideas on what to replace next or work on next?
