Are these good quads. I'm doing some work on one now for a friend who doesn't use it much and might buy it. Having some electrical issues as none of the lights work so any hints on troubleshooting that would be appreciated. Starter needs new brushes but I can handle that. Runs goof. Any ideas on a fair price? It's a 2005 I think.

There is a little white plastic knob to adjust the idle near the base of the carb.
