2000 SLX runs great for an hour or so then shuts down while riding, it's a slow shut down like a lack of fuel. I just cleaned the carbs bc I thought that was the issue but still having problem. It takes an hour before it starts to act up. I'm in between fuel or overheating. The MFD is disconnected so I can't tell if it's getting hot but it doesn't seem to be when I pull the seat? Any thoughts??
