I have a 2003 dr200se. Tonight I was riding back from work on the freeway, as I was accelerating going probably 55ish I heard a weird banging noise and thought it was my stuff strapped to the back. But as I pulled over I smelled smoke and when I got off smoke was coming out of the exhaust like something was burning inside. Once it stopped smoking after like 5 or 10 minutes I tried to start it but the starter made a weird half trying noise. As I pushed it home I tried starting it periodically but always the same until eventually nothing at all, but that's probably just the battery. I know very little about bikes but I feel like it's gotta be pretty bad since the knocking and burning and it was running great before that moment. I cleaned and rebuilt the carb a few months ago after it wasn't getting fuel. I don't know if I could have screwed something up then but I ride it everyday and that was over 3 months ago. The bike died on my way home tonight. Anyone know what caused this, I couldn't find anything matching this Googleing.
