EOBD light! Help!!!!

Hello all,

Just bombing down the A12 when my EOBD light came on (the one with what looks like a picture of an engine) it stayed on for a couple of minutes, went out and then twenty minutes later came on and stayed on for another 5 or 6 minutes and then went out.
It's a Monster695 - 2k miles on the clock and it had its first service 1k ago.
I've done about 3 hours of riding today with a few hours inbetween each hours riding so my bums numb too but I dont need any help with that.

Any ideas what it means???
