I'm guessing that the old 'stale fuel in carbs' may have been a contributory factor too. Certainly took a mile or three before it started to accelerate cleanly through the rev range - initially was hestitating at around 6k, refusing to pull past it a couple of times. Once it was cleared out it was running as sweetly as I could ask for. Aye, they are that.
I've had something similar in the past. The foulest tempered and most reluctant machine becomes sweetness and light simply by changing the (newish) plugs. As you say, odd.
