Having been the service manager at a bike shop..
If you are going to deny a customer warranty service you need to have a good reason. If there is direct correlation to the failure and something the customer did (or didn't do) to the bike then yes, but "Our Policy Is...." Usually won't cut it. The shop needs to find "cause and effect" By the way, the diagnostic time is billable shop time, so you may not get it fixed and have a bill at the end. Rage? You want to see someone go into a rage...
This next part isn't going to make me too popular - but if you add an aftermarket exhaust and a power commander the bike will no longer meet emissions limits, a big thing here in the golden state. There are road side emission systems set up randomly and every time a loud piped HD goes by and it's way over the limit, you can guess where the bureaucrats are going to go with this, and we won't like it. These things move around and you don't know where they are.
Things that wont:
Servicing the bike yourself. Keep the receipts of the parts you bought. But, if your work caused the problem no.
Cosmetic things generally wont, but can if they cause the problem. Example, install a pair of Apes, then extend the switch wiring badly. Shorts out, burns wiring harness and ECU. Example of not covered. We had this. Customer got the manufacturer involved, they came out and examined the bike. Once they found the cause and effect no way. It's just common sense. Repainted the tank, painter didn't seal the tank up, lots of over spray inside. Came loose, got into the fuel injectors. Not covered.
You install new pipes and a power commander. You don't get it right and burn a valve. Not covered.
Change your own oil use a after market oil filter and weird oil Spin a cam baring. Not covered. Starter drive comes up slipping, JoJoBa Bean oil in the primary. Not covered.
You get the picture.
