Hi from the new guy, Searched for an hour for something relating to my issue. Now I will post. I have a 2005 883 HD Sportster. Had it for a year. It sat in the garage for the winter while the military sent me off to the great unknown. Came home in the spring, started fine but after getting warmed up it would cut out when coming to a stop and be difficult to start. I thought it was overheated as I have to wait in line to get on base through the gate. Then it got worse. It starts and runs fine from a cold start. As soon as it get warm it stalls at idle speeds. So I stoped driving it as it stalls all the time and make like inconvienant waiting to start it to drive five feet and cut out. Thought it was bad fuel and gummed up carb. Well, after a couple months I researched the CV carb on my bike to see what I could do because I hate spending money. Took the carb off cleaned it with carb cleaner. When assembling it I was carfull and ensured no gaskets or rubber diaphrams we out of place or pinched. Reinstalled the jets. Reassembled it. Started the bike. Now it runs fine at idle and continues running even when warmed up. BUT, when I slowly turn the throttle it wants to die. Like its flooding out. If I quickly turn the throttle it revs up fine, but if I do it slowly it will sputter and sometimes die. With the air cleaner off the fuel looks plentiful. But the CV "pistion" (not sure on the technical part name) does not move as I slowly apply the throttle so I thought it was starving for Air. If I quickly turn the throttle the "Piston" moves up as expected so leads me to believe there is not a vacum issue. Sorry for the long explaination, but I wanted to fully explain the issue.
