The jet kit is OK, one thing you need to do is to pull the slides and sand them smooth with 1000 grit and them polish them to a mirror shine. Drill 12 1" holes in the air box lid and block off the intake snorkel to the airbox. Check ebay or your local dealer for a set of 02' prairie velocity stacks to replace the ones currenly installed.
