Right, so where do we stand on this then?

Keep it religiously below 4,200rpm for the first 1500 miles

or

just take it gently for first 50 to make sure everything is bolted together properly and then ok to cain it every now and again?

Or should I just ask my friendly salesman at my OPC and see what he says?

Just had a call to say I can collect at 3pm tomorrow
