OP, the engine will be fine. There's always the 100-200ml that won't drain plus it's not like you dumped the remaining half a litre in one shot. At any rate, you were most likely running within the range and even if not the engine has a tolerance.
As for dumping money on a dealership (the whole 1st/2nd service), do yourself a favour and do your oil changes (that's what these "services" are) yourself. You'll save about $250. If you can't do that, any bike shop will do it cheaper than a dealership. And don't worry, it will not affect your warranty. A dealership is forbidden to force you to service your vehicle with them.
