I have a 675 that has a brand new charged battery, a brand new regulator rectifier and a stator that checks out as in working condition. I just charged the battery, and it wouldn't start. I jumped the battery, bike started. rode it about 2 miles, turned it off, tried to start it again and engine barely turned and would not start. tried to start it again, same thing. it often just makes a click noise followed by a quick zapping noise when i hit the ignition. this thing won't start and i feel like i have exhausted every option so far. any suggestions.
