Members I am new to the community I would like some advice or help of any sort for the problem i am facing with my Yamaha FZ-S.
My Bike sometimes just loses its power when I throttle it and then comes to a halt and then when I try to Switch it On with Electric Start Or Kick Start It Just doesnt start. Now when I adjust the fuel cork to reserve the bike starts and Runs Fine.Point here is that the fuel is still there in my tank. In fact on One Ocassion I filled my bike and then After some odd 15-20 km the same problem occured.

This problem is really getting to my nerves need some help on this one

There will be a small hole somewhere on your fuel-cap which is a pressure equalizing valve . This may have become blocked with dirt . The classic symptom of this is the bike stops like it has no fuel and cannot be started until the fuel cap is opened & closed again .Have your Yamaha ASC service check and clean it . Also check the fuel petcock , fuel-strainer inside the tank and the air-filter for blockages .

Sir thanks for the help but can u please illustrate on where exactly can i find the fuel strainer and the fuel petcock is it the knob type thing which is used for putting the bike on reserve, on and off mode for fuel supply?????

Yes , that on-off-reserve tendu below the tank is the petcock valve . You've to take it out to access the strainer inside it .... etc etc . But I think you'd best leave all this work with the yamaha service center people , just tell them your problem and what you want done . This is a common problem and they know all about it .
