Post Zuma 50F stalling at lights
Heya, I have a 2012 Yamaha Zuma 50f and while waiting at traffic lights it will die when I give it gas if I am idling for 1 minute or more and the only way to start it again is to turn the ignition on and off, can anyone help me diagnose this asap please.

Thanks!!

A friend of mines 125 s had a fuel pump issue that he had a similar issue with .
Your bike is fuel injected like his .
He went through checking all the throttle positions sensors pulled the cylinder head and finally got to the fuel pump.
But i would start with something easier .
Do you have a copy of the service manual it is available on the forum .
Has this just started happening or is this bike new to you .
It maybe something as easy as a cracked breather hose .
