Hey all, no question here just a useful tip for anyone who might have this same problem. My bike seemed to rev wildly and die down and just fluctuate all over when it was idling. Sometimes the power would cut way back as I was speeding down the road. Scary, possibly dangerous and most of all annoying! I figured it was a fuel problem, I assumed it had to do with air bubbles in the gas line because my line is such that my fuel filter is not flowing "downhill" but has a bit of an upward angle.
I looked around on the threads and found a similar problem, somebody suggested that the "float fork" in the carb was possibly the culprit, to disassemble and check fuel flow. I took the float bowl off and discovered the brass tube that goes though the "donut hole" of the float, through which the needle slides, was just hanging on by a thread, so to speak. I tightened it in all the way, it had almost a 1/4 of an inch to go, reassembled and bam! Nice smooth idle. It must have slowly unscrewed with vibration, this may be something to check during the original build. Make sure it's in there tight! Hope this helps somebody, I tried to make the title searchable for the symptoms.
