Just bought it last week & rode it home about 12 miles in flooding rain. I took the battery out and took it to have tested & it is good. put it back in the bike and it started yesterday. Didn't go for a ride after. Went to start it today it started then died when I took off the choke and wouldn't restart just a buzzing sound. Not turning over. Lights, & horn work fine. Starter or ? Any suggestions on where to start I just spent all my saving on it...it has 14k on it and looks to be in very good condition otherwise.
