Jeep, the bike idles at 4-5K with the choke off??? Have you thought about adjusting the idle speed? Stand looking at the left side of you bike...the idle adjust knob is below and just to the right of the petcock. Here's a picture. The grey hose at the top of the pic is the fuel line. On the radiator, it's normal for the temp to climb while sitting at a stoplight....as long as it's not going into the red, don't worry about it. I normally hear my fan kick on right after I shut the bike down after a ride. If it's not doing that, you may want to have it checked out.
