Just now saw this thread (I need to nose around more often!). Nice write-up on your progress, "The Jerk". Here are a couple of shots of my 2000 model. Mine is still pretty much stock except for a few add-ons. The carb jetting is stock, and the pilot screws have been adjusted. I get only a little popping on decel, and none of the backfires some of you seem to be experiencing. I really have enjoyed this bike.
