I've had dealerships put stripped out bolts back on the bike
When I first bought my bike, I bought the full exhaust and had the dealer install it. They dinged the radiator up and didn't properly align the midpipe to bolt it to the frame
I've had dealerships put the wrong part on because they were out of stock with the correct one
I've had dealerships reuse gaskets and seals on a $400+ service, which ended up seeping and making a mess on my engine
Every single instance above, I had to fight tooth and nail with them to make it right. I wasn't always successful
I now do all my services myself. Including tappet clearance and throttle synchs.
