24,000 km service

What's a ball park amount that I should expect to pay for a (major) 24,000 service - 2015 GSX1250fa  ??

With valve clearance check, plug change, oil and filter, probably about $550. Airf filter should have been done at 18,000kms. If not, and it gets done at 24,000kms, then over $600.

I did my own oil & filters brake pads & fluids etc . etc . & got them to check valves , change plugs while they had them out & same with the coolant  & check throttle body balance . They charged me $ 400 to do their part.
