Am I missing something? I haven't seen a reserve on this bike.

There is definitely a reserve switch, but there isn't an actual "reserve tank". When the fuel gets low it shuts the fuel pump off and when you switch it to reserve it overrides it and runs the pump anyways. It's just above the start button (a left to right switch). I believe left is reserve and right is on, im at work so i don't have the bike in front of me but I believe thats the orientation.

Don't think it'd be the reserve then, cause the pump definitely turns on. Just doesn't suck any fuel from the tank. Guess I'll be getting a new pump. Any suggestions? Saw Chinese cheapos on e-bay for $15-40 and new Yamahas for $250-300. Don't know that I wanna throw $300 into a project bike right now.

I've got good used OEM pumps and be cautions of the cheap ones that likely don't have the built in pressure regulator. You may simply have a displaced diaphragm if it doesn't pump. Another thing to make sure is that there is no air leaks on the side prior to the pump. Even a very tiny hole will cause it to lose the ability to suck fluid even if that hole doesn't leak fluid. Picture included of a displaced diaphragm.

How much for a good used one? I don't really want to put another cheapo Chinese one in, cause that looks to be what's in it.

Make sure your tank vent line is clear and not pinched.
