Since this is my first post here, maybe I should introduce myself. I'm 53, living in Sweden and last year bought my third FJR ina row. I've been around this forum for a couple of years and never stopped being impressed over the professionalism here.I had the light come up, due to running the bike through the gears on centre stand, cleared by the dealer.
Now to the topic: For my two first FJRs I have made the same action as Damir i.e. been running the rear wheel on the centre stand with different gears and never had any problem at all. Yesterday I made the same action with my present FJR, a -19 AE model (ES in USA/Canada) and there it was: A bright and clear engine light failure.
After some googling I found out that several people in Scandinavia have had the same problem with Yamahas last year so it might be so that Yamaha have added this failure function quite recently.
Called my local Yamaha store and it seem like they can fix this within "no time".
