One other question. When I ride to work and I am going around 45 or 50 and need to stop at a traffic light, when I stop the bike the revs seem really high. I mean really high. I don't have a tac, but it sounds like the engine is still running does when riding at a higher speed. That's not good, right? What could be causing that?

Likely a vacuum leak or the carb is hanging up. Does the throttle grip close smoothly by itself? The cables may need lubing.
