1983 200e how can I get to my front sprocket? Book says half the case comes off...

I have another post going regarding a surge at constant throttle, found this to be the real cause. Was very misleading.
I rotate my rear wheels and every few revolutions there is a binding. The chain even tightens up, spin past that hard spot and the chain drops back to normal tension.
Rear axle spins true. Can't find anything bent. I do hear some sort of rubbing sound from the front sprocket area, but I can't see it to diagnose. Instead of going full removal at the moment I just want to get eyes on the sprocket and see if I can tell what's going on. Maybe you guys here have had this before and can tell me?
So I started removing the flywheel cover and stopped to ask this. Can I get eyes on it by just removing the hi/low box?
I don't believe there's any bent shafts, everything spins too many revolutions between the bind/hard spot to be that. I'm guessing a bearing, or possibly the sprocket is walking on it's shaft.
Has anyone had this issue and can anyone tell me how to just get eyes on the sprocket? Thank you!

Nevermind my issue was not the sprocket! It was a single bound link in the chain that doesn't want to bend! I have posted all about it in my other post about the surging Honda 200e at constant throttle. Awesome site with very good advice, staying a member here for life!
