What s wrong with my motorcycle?

Hello, in the start of fall I accidentally jump-started my Honda cm185t Twinstar 1978 with reversed polarity. I saw a wire on the rectifier smoking and replaced it with a new wire. No fuses I can see are blown Once I put the rectifier back on the bike,it started up and turned over. Both cylinders fire only when I press the starter button and hold it in. It also doesn t Rev correctly without the starter button being held in. I need to know what do in order to have my motorcycle working correctly, Any advice you could offer is greatly appreciated. Feel free to ask any follow up questions you need. Thank you.
