Question about 2006 Yamaha Road Star Midnight Silverado
2006 Yamaha Roadstar Midnight Silverado 1700, 6000 miles, completely stock, pukes gas from carbureter when the engine is hot. Bike will be hard to start, run for a few seconds then die and gas gushes out of airbox. Holding throttle wide open when starting will get it started and burn off excess fuel. Only happens when motor is hot. Also has clattering sound from motor when hot and accelerating and cruising at higher speeds. Sounds like pinging. Have been told that the fuel is boiling in the bowl and/or fuel line because of position of carb. Yamaha says use fuel from large domestic producers and use premium gas. I say bull. Can find no recall or tech service bulletin. Factory says they are aware of problem and its "fuel quality" problem, not theirs. Star Owners website say there have been fires and to report to NTSB. Help!
I had this same problem. What I discovered was the float needs adjusted on the carb. I set mine lower inthe bowl and it stopped the leaking. Reason for this happening is on hot days the fuel in the bowl will boil. This boiling action dumps in more fuel and the carb spits it out the air breather.
