Have you done the major service at 30,000 miles for the HP2 Sport? What did the engine look like and is this partial engine rebuild really necessary if normal sporty riding plus odd track days was done? How many hours allotted to that inspection?

Would call them directly since a lot of places don't check here regularly. They might also have specific questions about your bike that they could answer faster than texting back and forth.

I'd say just adhere to the manufacturer specified maintenance requirements, and pay the dealership to do the job correctly. After all if you shelled out the cash for a HP2 Sport you should be able to pay for the maintenance intervals.
