OK, here's how it went...a friend of mine opened his own mobile motorcycle repair. He came by today to diagnose what could be wrong. (By the way, he used to work for a dealer and has personally rebuilt 70 or so 1600 motors due to the tranny recall) He listens to it run, pulls the plugs and says "Hey, this thing's running a little fat". So he pulled the carb, moved the needle from the 5th to the 4th clip from the blunt end and changed the main to 167.5 from 170. Runs perfect!!!!! Also the problem a few of us know about the choke cable somtime not closing all the way is caused by the cable sleeve pulling out of the crimp by the knob. He pushed the sleeve back in all the way and now the choke pulls out farther (and closes all the way too). He also told me the the plastic retaining nut also has a tendency of breaking after a few years and that the dealer only sells the cable as a kit .... Just have a hard time believing that jetting was causing the problem but I'm glad she's purring the way she should.
