The TCI on an 81 is different than the 80's. Pre '81 used the 2H7 and the '81 is a 4RO. The rotor under the timing plate is different too, and the wiring harness was slightly different. The pre '81's have a mechanical advance, while the 81's don't. You might be able to get it working by swapping out the mechanical advance and the plate with the pickups on it from the 80 to the 81 motor. You'll have to drill out the tamper proof bolts to get them off. You'll have to get some new bolts, and then you will have to set the timing.
I think I have a loose screw behind the handlebars.
