I completed a stage .5 mod on my 1200 XLH a few months ago.
(SE air cleaner, 45 and 180 jets, punched out baffles on HD slip ons)
Initially, I did not adjust the idle mixture; however, it appeared that I was running too lean (lots of carb farts). I readjusted the idle mixture about 2 1/2 turns from the closed position with nice results. No more farts and nice throttle response. I just checked the plugs after about 250 miles and the plugs indicate that I am running too rich (black soot present). I am planning to change plugs today and reset the idle mixture about 1/4 turn. Does it sound like I am on the right track? How long do you run before you can recheck the plugs ? Thanks
