Sunday I met the wife at out camping property, nice ride up into the foot hills. Love my cruising foot pegs, coming home I was bucking a wind on and off. Road did a slite bend to the North and now the wind was coming at me @ a differant angle. Then, no power

twist the grip nothing. Switched petcock but I was full tanked. Brought my feet back to pegs and zooooom off I go ? Put my feet up and lost power no matter how far I twisted the grip ?
Looked down to see of the vacume hose came off, Nope. Wife was fallowing me freeking out, figured I was going to fly off the road. I figured that there was a air flow change to the intake of the air box. Anyone have this experience ?
