No, I mistakenly thought you were refering to the needle jet holder/emulsification tube. Forgot that pilot jet had some as well I'll go back to sleep... best of luck.

The pilot jet doesn't have holes in the side. The pilot jet is a small single flatbladed screwdriver removable item about the size of a small pea with one tiny hole through its centre.

non runner = standing for long time = blocked pilot jet (more often than not)

Yes, you have a fault code 19 - basically a problem with the black and white wire (or its connectors at either end) between the ignition switch and the ECU. It might be easiest to start at the ignition switch working back to the ECU. The ECU itself is located within a rubber mount on the top frame tube under the tank about 6" or so back from the headstock. To remove the tank you'll need to remove the rear tank bolt (12mm), the link bar between the two black plastic air scoops attached to the underside of the tank(10mm), the lower fuel pipe that feeds the injector - remove small crosshead security screw, lift away plastic shroud to release the safety tab (push upwards)to access the two release buttons which need to be pressed in together to release the pipe from the injector unit. A small amount of fuel will leak from the pipe. As you lift the tank you can unclip the feed to the fuel pump. Do not lift the tank up too high or ypou wil ldamge it against the bearing cover located on top of the steering head column. Having removed the tank which should take you no longer than 5 mins, you can then try and locate the problem ric.

I've been looking to purchase a smaller rear (1 or 2 teeth less) for my '09 fuel injected YBR since carrying out a few subtle modifications which has left the engine revving into the red and hitting over 10,000rpm in fifth gear on occasion. Could anyone please advise where I might actually purchase one from or if there is another Yamaha model using a sprocket of identical dimensions but has less teeth? ric.
