A mikuni jet kit is something most two-strokers end up purchasing at some point. These kits come with a complete range of main and pilot jets along with some special needles. JD Jetting kits are a popular choice as they provide a full range of jetting in a box and they are bike, year and altitude specific. Their needles feature a multi-taper design that they claim improves throttle response. The kits are priced in the $85 range and can save a rider a lot of time and money that would be spent on experimenting with various combinations of jets, needles and needle positions.
