After reading this I decided to give it a try on mine. I originally had the 42, 142 jets with two shims on the jets and decided to move down to 40, 138 with no shims. I have the pilot screws out to roughly 2 1/4 turns. But reading this again I could turn that all the way in and still be fine correct? Even with the new jets coasting down hill in gear I'm not hearing any "backfire" which I believe the bike needs. Also before moving down to the smaller jets I checked the easier to remove plugs and I had a white tint to the tips. They were not wet. I want to recheck them in a few days to see if I notice any difference. Besides the ear shave I also have the Vance and Hines pipes. So just want to verify before turning them in that this won't cause a problem if the bike idle and rides fine that way. Or should I just move down another size on the pilots.
1992 Vulcan 750.
Ear shaved and re-jetted.
