Thanks alot for confirming that Kev.
When I tried to explain the situation to my dealer (I was worried about the petrol in the oil and any subsequent warranty issues) the young mechanic got all text book like about switched earths unlikely to be from the ECU. I was starting to wonder if the FI lead was just a coincidence to my problem. 100% duty would explain the amount of petrol in the engine oil!!

I guess the FI lead is potentially just another addition to the list of known issues???

Anyways, the Tenere is still a great bike - at least it was at last years price!!
