Jet kit....why?

You don’t offer any indications as to why a jet kit would be needed so a quick lesson here. If your bike runs well and performs properly, your jetting is probably ok as is. A carburetor jet is a jet. A little metering orfice for fuel to pass through. Most JD kits use the same jets as the factory supplies. The JD needles are mostly proprietary and calibrated perfectly for optimal performance. your jet kit is simply a tuning recipe calibrated for your bike with an assortment of jets and needles. If your bike runs without any performance issues or complaints, you probably won’t notice a difference from rejetting your carburetor as your current factory tuning recipe is okay. I have seen my share of wannabe tuners try rejetting kits and fail and revert to stock settings to restore performance ruined by incompetent attempts at tuning. Just sayin
