Hello.. Yes. I´ve had the same fault. I´ve done 1200 miles. I rang the dealer,White Bros in Darlington,and spoke to Ian in the workshop. He thought that the ECU needed to be re-set. It was done last week and has cured the fault. I was told that this is normally done at PDI. Mine hadn´t been. I wonder if yours is the same ? It´s like the bike described in the road-tests now.. Regards. Bill.
