When it first started it was a one off, to get over it I put a bit of throttle on with the ignition button in and it started. Today it did it to me once more! this time even putting a bit of throttle on did not help, I left it for 2hrs or so and went back to try it and it started?? Can someone please help? I had a look at the air filter as a friend said this might be why, it was not, as i did try it without the filter on and it was the same. |
Hi, your Yamaha is fuel injected so should fire up on the button. As the machine is turning over you should hear the fuel pump "ticking" as it primes the fuel injector. If this is not working check for power to the pump, if there is no power trace the wiring back to find fault. If however you do have power to the pump, then you have a faulty fuel pump. But the most likley fault is a worn inlet valve guide. This wears prematurly and the inlet valve does not seat properly causing rough running and aventually it will not start at all, this will require a cylinder head replacement . The easy way to check this is to get your local garage to run a compression test or if it is still under warranty ask your local Yamaha dealer to look at it. |
