Just had my first "major" issue with my 09 Ten and thought I'd better share it in case there is a common problem (my dealer has asked for photo's so he can inform Yamaha).

Whilst returning home from Birmingham last Thursday I ran out of petrol prematurely after only 59 miles on reserve instead of the usual 80-90 miles.
I normally ride at half to three quarters throttle hence 60-65mpg. As reserve is 6.3 litres, 59 miles equates to about only 42.5mpg!! Even allowing for thrashing the bike, the lowest I've had previously was approx 55mpg.
After a little top-up the bike wouldn't start but stunk badly of petrol.

Spent most of the weekend checking all the usual culprits to eliminate them. On the one occasion that I did manage to briefly start the engine a considerable amount of unburnt petrol was ejected from the silencers - not the usual misfiring situation I've experienced before with previous bikes!

Whilst checking the injector (I assumed it had stuck open somehow) I noticed signs of corrosion around the FI lead and frame.

The FI lead exits the wiring loom between the loom and the frame. As such the paint had rubbed off the frame and the red/black wire of the FI lead (to ECU) had chafed to the bare wire and so was shorting against the frame!! My first thought was "that's a clever bit assembly-NOT" (or words to that effect!)

Needless to say, bike runs fine now that I've patched it all up.

Being a courier I do alot of miles - over 51,000 since end of March 09 - but regardless of more than average wear and tear this struck me as a breakdown waiting to happen.

Might be worth Tenere owners checking their wiring loom just in case.......especially if they experience misfires/bad running with excessive amounts of unburnt fuel.

And put some foam between the loom and the frame

Hope this is of use.

Cheers,
Rick

PS. Do the X's & R's share a similar wiring loom???
