Stumbling at Low-Throttle?

[SilverBullet]

I have an 04 Sportster Classic 1200. I have the Screamin Eagle Stage I Air Cleaner and Screamin Eagle Slip-Ons. I re-jetted the carb myself. It ran fine last summer, but this summer it has stumbled quite a bit at low throttle situations. Like cruisin down the highway in 5th at 55-60. It doesn't run smooth. I put up with the problem all summer, because I haven't had a lot of time to ride. I honestly dont remember exactly what size jets I used, but I do remember puttin 3 washers on the needle??? Any advice guys (and gals)?

Low jet should be 45/46 with the washers I would use 2 of them instead of 3.

I believe I used a 45, IIRC. I will try taking a washer off and tweaking the mixture screw to see if that helps.

you might have to take the carb apart and clean it out. mine started missing up real bad about a month back. i had rebuilt it a couple years ago because the accelerator pump was bad, anyway i took it apart and blew everything out and all is good.

Hotrod351 has a good point, but only do the rebuild AFTER you get the other problems sorted out...i.e. running at least as well as what it was, then you have a known setup with fewer variables. Here is a link to help once you get the problem sorted and want to rebuild the carb on YOUR terms. :s
