What the ****did i do wrong

got a 02 sportster883c just installed new plugs gaped at .040, and now have a miss and experianced run-on after shutting it down [ first time for this ]. First harley and it seems like I hear all kinds of problems while riding. been told its the nature of the beast and nothings wrong ?

check the wires,make sure you didnt accidenly pug one out of the coil a bit,if not that,try another set of plugs,seen bad out of the box more than once

thanks. Changed out the plugs today, went with harley plugs, made a little difference. noticed when I removed the old plugs the back plug gap was maybe .020 and the .040, so I set the gap on the new back plug at .020 and now runs alot better, like before i changed them the first time. whats up with that ? any ideas

Should fire at .40 gap unless you have a weak spark. Wires,coil,timming

.020 is a very small gap. Something else is wrong if that made it better. Check wires, coil, etc. And yes, Harleys do make more noise - part of the charm.

well the question was what i do wrong ! if this is your first harley . and your first bike the purchase was wrong . lol . just bustin your chops . split the diffrence in the gap 0.37 should be fine sportster are noisy little bastard your turning four cams all gear driven . they make a racket no biggie . start it up no choke give the throttle 2 turns fire it up hold the throttle at a grand and warm it up . then take it for a ride see how it runs . some motors are a little cold natured and take a little to run smooth . then to finish your tune reset the carb up . follow the directions that they have in the help section , you would be surprised how many carbs are set up wrong and when done correct the bike will perform awesome . congrats on the sporty and enjoy.

thanks all ! put on new plug wires, reset plug gap, and now seems fine, THANKS
