Hi Guys, new to your forum here... My wife and I own 2 HD's a 2002 Fatboy and a 2004 Sportster 1200C. The problem we are having is in regards to the 1200C. The bike starts up perfectly, idles great and initially runs good at low, medium and hi throttle. The problem is after complete warm up I can't roll off idle. It will idle fine but as soon as I start to roll the throttle is coughes and sputters and backfires very badly. If I jocky the throttle around a bit and get it to catch it will still run good at medium and hi throttle. I have taken the carb apart, completely cleaned every piece and reassembled and problem is exactly the same.
The specs:
*2004 1200C
*HD Air Cleaner Kit
*SamsonUSA "Big Guns" pipes with "Tourque Cones" and Short Baffles
*Added a #45 Slow Jet
*Idle Screw out +- 2-1/4 to 2-1/2 turns
*only 2000 miles
*Fresh Premium 93 Octain Gas
*Just took carb completely apart, cleaned every part and reassembled.
I'm wondering if the bike is just running lean the entire time and then getting too hot??? I've tried searching this problem on line and have had no luck. Hope someone here can help. Yesterday it was somewhat cool at 65* to 66*.
I road this bike for nearly half an hour with no problems, get back home leave it idle in the drive for just a few minuets and it starts acting up???
Thanks in advance for your help.
