Your bike came in at 80 HP, the 99 year model had 86 HP you can check and see if that year had a larger pilot jet. you are running leaner because of increased air flow. Excellent in you can get more fuel with it. You should be able to go up to the next size and cure your problem. Your Pilot Jet is 75% cruise Mixture and 25% idle mixture. Rule of thumb.... If you go 1 size larger or smaller on the size of the pilot jet, you will change the fuel screw ~1.5x richer or leaner to retain the original idle mixture - Dennis Kirk 6am to Midnight Central: 1-800-969-7501 tell them what you want.

No one can tell you what jet size to use unless they know exactly what exhaust and jets you have now. The best thing for you to do is go back to a known good configuration. If it has never run right since you had it, go back to stock (make sure it runs right with stock settings now!) and start your adjustments from there. Change one thing at a time and do performance testing between each change. Dyno runs are best, but timed runs might work too, depending on your application.
