Electric Smoke
 

I have a 2005 suzuki boulevard c50. I had to change the battery. I went to start it and it struggled to start twice in a row. It did start but I notice white smoke and an electric smell that came from the front of the motorcycle, maybe close to or from under the gas tank. It disappeared fairly quick. After that started it several times with no issue. I tried to chase down all the wires but did not find any melted wires or bad connections. Any help would be great, thanks!
