Just had a precursory flick through, some good advice on here for 'newbies' (and a few that are good advice full stop) thought I'd throw a few in if you are taking your bike to work at a dealership.
1. Clean it, it doesn't have to sparkle, but a quick hose off before is always appreciated.
2. Don't bring it full of fuel, if it requires valve clearances, air filter or any of the myriad of jobs that require the tank to be lifted off. full fuel tanks are heavy.
3. If you think something is wrong with your bike, don't storm in screaming, be nice about it and your dealer will most likely bend over backwards to sort it out., be friendly, and explain what you think is wrong with your bike. 90% of the time its an issue we have seen before and can easily sort out.
4. You CAN repair most punctures even on sportsbikes! no need to bin that new D208 because its got a nail in it!
5. If you have been tinkering with your bike and now it doesn't work, be honest. tell us what you have done and we can fix it in a jiffy. trying to save face by denying you have stripped the front end down will cost alot of labour when it turns out you have bolted your bank angle sensor on upside down. not to mention how silly you will look, (this did once happen!)
