Do you have to have HD jet? I used to race dirt bikes and there is a place on the web that sells jets for every carb and drastically reduced prices. It is first rate brass, no Pakistani stuff. Let me know and if you are interested I will spend some time and see if I can find the site again.
27165-90 is for the #48 and 27114-88 is for the #180. In the event that the stealership does not have them, tsk tsk, then find a kawasaki dealer and tell them that you have a 1997 vulcan ultra classic 1500, as they also use a cv 40 carb, along with the same jets. Now, if some one could find me the number that is stamped on the stock needle of an 88' sportster XLH 1200.
