The NZ DJ kit comes with the needle, e-clip, washer, 150, 155, 160 main jets and some stickers.
Jesse's kit is the US kit that also comes with 165 and 170 mains.
The main difference is that what Jesse recommends you use is much closer to the truth than DynoJet's recommendations.
Opened airbox, open pipe seems to have a baseline DJ tune of 160 main and needle 4th from top.
