I hope you had both tyres replaced at that price or the dealer at least gave you a reach around

the 10000 mile service use to include checking the valve clearances but as no one ever needed them adjusted at 10000 miles I heard they then moved it to 20000 miles one of my rockets never needed any adjustment until 44000 miles and even then it was adjusted just because the cover was off.
The valve check is what made the 10000mile service so expensive apart from that it is just an oil and filter change and probably checking a few things that you should be able to do yourself.
