Unhappy Stalling '86 K-100

After riding my bike on hot days and for periods greater than 20 minutes, I will notice the smell of gas when I am stuck at traffic lights. When I accelerate from the traffic light, the engine starts spitting and ultimately stalls out. I then wait ten minutes before the starting the engine and get on my way again. My mechanic tried to isolate the problem last year but didn't find anything wrong. Any suggestions would be appreciated.

stalling

I think i would look for a clogged fuel tank breather line, or maybe pinched. It sounds like you are starving for fuel.

Sounds like vapor lock to me.

next time it stalls, open the gas cap. if it sucks in air and then starts you have a tank vent issue. there are 2 drain hoses under the tank, one for internal venting, one for overflow/water draining around the cap. replace both hoses and run them to ground down by the centerstand.
