I have (2) Kawasaki XI SuperSports (1993). I just got them and do not know much about them, I am learnig though. Anyway I was planning a trip to a lake that is at a pretty high elevation, a buddy of mine told me that I might have to adjust the air flow for the carbs.... HOW DO I DO THIS?? Would really like to do it myself so that everytime i go somewhere I dont have to take them to a shop to have that done, thank you very much for ANY input
