...not running properly.? I went to start up my bike and it 'sparked' on the right side of my engine. I started it up again but nothing happens, just makes this dead sound (don't know how to describe it). I attempted a few more times and it's now working but when I ride it, it just dies on me and having to keep on starting it up again. It was working fine three days ago. What's wrong with it??? please help.....
