If motorcycle has set for more than 6 month with the new reformulated fuel, the carbs are probably plugged up and need cleaning. Also check for any broken, open, or otherwise damaged vacuum lines as they will also make it pop and spit. The inlet spigots that connect the carbs to the head also may be leaking and will case the same type of problems.

2003 harley davidson sportster 1200 custom. runs fine shortly then dies with spurts of fire. the light stays on and if i pull the clutch when its still running, it goes back to normal idle and responds to...

It sounds like a fuel starvation problem since it's spitting back out of the carb. Check you fuel cap to see if the vent is working. Loosen the cap and ride and see if that makes any difference.

Also, if your bike is equipped with the original vacuum equipped petcock, there could be problem with this as well. I've seen them get holes in the diaphragm and I've seen cause a vacuum leak. Check the vacuum hose and diaphragm. You'll have to remove the petcock from the tank. Personally, I'd recommend that you change the petcock to a high quality manually operated petcock like a Pingel.

Good Luck

Layed up my 1200 sportster for 8 months while running rough with high idle when normal temp and cutting out thinking carb .ive adjusted the idle but still not right

If your bike sat for that long with fuel in the carb, it's probably gummed up the carb on the inside. The carb needs to be disassembled and cleaned out on the inside. This is job best left to someone who is experienced in this area.

Wondering if anyone knows where the adjuster for the carburetor is located on a 2001 1200 Sportster custom

Unless the carburetor has been modified, the only adjustment is the idle speed. The Idle Stop screw is located at the upper right side of the carb. You may have to remove the air cleaner cover to access the screw. Clockwise rotation increases the idle speed. Adjust the idle speed with the engine at full operating temperature.
