I didn't hear anything that sounded odd.
Was the engine warm and the choke off at the time? If so, I'd check your idle speed - it seemed too high.
EDIT: As JR pointed out below, a 250 F.I. engine isn't going to have a choke (didn't catch the Euro model info), but it's still running faster than I would expect it to unless it has a pretty high "fast idle" when cold. My F.I. bike idles only slightly higher for a few seconds before dropping back to a normal RPM on cold starts in moderate temps.
Do the revs drop back down slowly when you give it some throttle and close it quickly when the engine is warm? That could indicate a vacuum leak as alex mentioned.
