Taffy or Yamakaze, or anyone else with experience on jetting: I finally got my parts and now have my jetting set up the way you folks suggested. See my signature for the details on my settings. The bike does run better but not yet perfectly. Once the bike is nice and warm and ridden for a little bit the bike starts to pop and hesitate on excelleration. I rode tonight and seemed like it ran fine for about 5 to 10 minutes. Then all of a sudden it started popping again. What's weird is by the time I got back to my vehicle, the popping stopped. I rode it around, back and forth, and couldn't get it to pop again. Could it be the elevation? I really didn't get more than 100-200 feet above where the parking spot was and a the highest point of my ride is where the popping was. I don't get it. Am I still too rich on my pilot or main, or both? Wondering what a change to a 42 pilot and 165 main will do. Could it be the gas? I'm running 91 octane pump gas with an octane booster. Could the octane booster be screwing everything up? I'm also heading to Southern California next weekend for a big ride. Wondering what jetting changes you may suggest. If I'm a little too rich here, could it be just right down there? The elevation down there will be about 2500ft as opposed to 4500+ around my home. And temps are probably gonna be around 60 degrees instead of my typical winter 40's.
