Thanks for the quick reply. I will try those two ideas this weekend and report back!
Starter spins on bench but won’t crank bike

Thanks for all the suggestions and warm welcome. I was able to get out the garage this morning and perform some of these tests/inspections.
I tried both putting battery positive to the starter lug without success and also tried applying a ground to the case. Same result. I did do the ground mod and I have a 0 resistance connection from the starter case to frame and also to the ground cable. I also measured 0 ohms resistance from battery positive cable all the way to the starter connection.
I did take the starter apart again and checked my work. A few things were observed. The armature did have a bit of rust so I cleaned that but I saw a separation in the armature laminations. I will try to attach pics. I also saw some what appears to be burn marks close to the commutator.
The motor turns free and does spin when out of the bike. I am thinking I need a new armature. Any help is appreciated.
