I have an 86 XR600R that I'm restoring I guess. I've had the dual carborators rebuilt, which started on the second kick. I finished installing my Baja Designs lighting kit and then took the bike out for it's first ride. It didn't run as good as when I installed the carboraters, would only want to run with the choke in the half way position. I checked to see if there might be a vacumn leak but the boots look good. I did have the bike serviced a few months back and was told the valves were adjusted. Any suggestions?
