I'm confused, did you fix the problem or not? Idling related issues are typically caused by a clogged pilot circuit. Not only do you need to clean the jets, but you need to spray carb cleaner in all of the circuits followed by compressed air to flush everything out. Soaking the carb is not always sufficient. Also check your float level as that may have been why you had to lean the bike over (to let fuel in the bowl). If you don't have a float gauge, you can use a ruler or do a visual check to get it approximately in the right range. Hold the carb upright and the float needle should close fully just about when the float is level. If not, bend the tab on the float slightly, check again, and repeat to get it within range. Also make sure you aren't missing the rubber o-ring and washer from the end of the fuel screw, and make sure the o-ring is seated properly. Starting from the tip of the fuel screw (the part that goes inside the carb), the order is o-ring/metal washer/spring. Often times people forget or don't know about the o-ring because it doesn't just fall out like the metal washer does when they disassemble the carb, and they either end up losing it while cleaning without even knowing it or it stays in there and gets smashed when putting the fuel screw back in. All of a sudden they have idling issues.
Please report back with your findings.
