Don't let them just put one new cylinder and piston in for 1800... my .02.
Good time to go aftermarket - a big bore kit.

I would more .010 over if needed.
Curious how they caught it. MDo they normall do a compression check or look at the top of piston?

Good that it was caught before it destroyed the lower end and valves by fragmenting.

My bike was burning oil so I had asked them to check spark plugs and put a scope to see whats going on in there.
I doubt they would have done that during regular service.

I would check out all your options before committing to the dealer. Talk to some Indy's as well. Get a detailed estimate for both parts and labor. With your mileage you should have the lifters, cam chain tensioner and crank run out checked as well.
You might also think about your big bore options.
