Why did you add a jet kit? Open air intake or exhaust? Larger or smaller jets and sizes? What did you do for needle adjustments? What did you set the A/F screws at? Did you do a plug chop?
Adding jets with no adjustments in intake or exhaust may create a dead spot since in a certain power band you have an improper fuel air mix. Adjusting carb jets is not as simple as just changing to different sizes as not all bikes are alike based on many different factors. I takes a lot of tinkering with the jet sizes, needle height, springs, and A/F screws.
