Electric Starter Fixed

I bought a rebuild kit for the starter motor. Glad I did. The end cap bush was oval. I found the reason it stopped working. Someone had over tightened the terminal post and torn the main internal connector off at it rotated. Replaced bothe bushes, brushes, lubed bearing and soldered the internal conductor back to the terminal post. Took we 4 attempts to reassemble, adjusting end float, until it spun freely with a bench test. Re-installed it and the bike fired right up, instantly ?
