If the book says it takes 1 hour to do the job, the 1 hour is all I'd pay. I don't care why it took the tech longer. Not my problem. (But then I do 99% of my own labor).
One thing I have heard and believe is that the MOCO doesn't pay the same hourly rate as customers and they don't pay the 1 hour (or whatever minimum). I also caught a car dealer that told me the failure wasn't covered by warranty, I asked for the used parts and the tech said they needed to return them as part of the warranty claim. They were charging me and claiming warranty.

 

Actually the MoCo pays warranty work at a rate less than if you brought the bike in and paid the service departments advertised labor rate. This is why some dealerships act the way they do towards doing warranty work. If a dealership has bad techs and they take longer than normal to "fix" a warranty issue then the dealer ship takes it in the rear. After doing this too many times they will eventually try to shy away from doing warranty work and want you to pay for the repair by trying to put off doing the repair(s) until after the warranty expires.

 

Warranty work is almost always good for a dealer, it's only free if they are bad at paperwork, which a lot of places are. The down side is it takes longer to get paid
