Franky - I had the same issue when the bike was 1st hot after say 10miles and the light stayed on if I recal for a few rides.
I have to say that I ignored it because the bike had oil to the correct level and the temperature as displayed on the dash was correct.
My bike seemed to sort itself out and doesnt do it now (im up to 2,500 in 3 months) - I think it was still doing it up to 500 miles.
Not sure my post helps but I would just check the oil level, watch that the temperature on the read out (normal running my fans dont cut in and only come on when I slow down after hammering it or i sit in trafic) stays under control and see if it sorts itself out over another 200 miles.
Cheers Nigel
