I installed my Jet kit yesterday only to find one already in it. So I just removed the snorkel. Should have open her up first. Oh well, now I have a question. I have the needle third down from the top per instructions, 160 main, and the pilot at 2.5 turns out. I am having a stumble in the low to mid area. Any comments? The bike does still have the stock exhaust right now. Want a "Q" bad hate the sound of the stock sputterer. Anyone have some good advise?? Oh Anyone want to buy a Needle and spring? Oh also an extra 160 main jet? CHEAP!
