That quad should be fuel injected. Have you checked your air filter for clogging. At high rev, you need allot of airflow.

I am inclined to agree with Ajmboy, it sounds like you aren't burning enough of the fuel in the combustion cycle, so it burns off in the exhuast making it get hot like that. A clogged air cleaner seems like the most likely thing to me as well. It would explain the stumbling in performance too. Check the air cleaner first, but if that is not the problem, I would check the throttle position sensor next. Also, there may be a sensor inside your air box, it is an air temp. sensor, that could be causing problems too. There is also an air pressure sensor on the throttle body, if that isn't reading properly, it will affect fuel delivery. I assume that the engine temp. light is not coming on, right?
