I seriously don't understand you. That front brake (yes, single caliper front brake) is the only thing that's really stopping your bike - not rear brake, not engine braking. You're putting yourself in danger for a few bucks. And the other thing is - if you change brake pads on time, you don't need to change rotor, but if you go metal to metal, your rotor is pretty much done. My first bike was GS500F and I loved everything about that bike, but carbs (just hate to adjust those things).
Replacement Rotors aren't cheap. Used ones for that bike, $100 shipped; new ones, up to $300. Perhaps he will understand when it costs him money.
