Hi
I would suggest that you have the valve clearances checked.
Also, check that the carb is clean. Pay particular attention to the PILOT JET as this opperates the idle circuit.

It sounds like the choke line may not have been routed correctly when the new one was installed. Remove the gas tank and check to see that the line is not being stretched anywhere along the way AND that the gas tank when re-installed is not stretching the line. The line may have been kinked when installed. Look at the mechanical movement of the choke at the carb. Does it operate freely? Remove the air filter and look inside the center of the carb, (you may need to use a small mirror for this), does it look like the choke is opening and closing properly when the choke is moved on and off?

With the oil problem I read on another site that Yamaha did that so that excess oil would be burned up in normal running (but this was usually smaller amounts). Anyways they disconnected the tube going to the air cleaner and had tied up in such a way that any excess oil would land on the chain thus lubricating it. But if you have that much oil coming out it could be that you have put in too much.

check valve clearances, and low voltage can cause backfire, battery voltage should rise when revved, use a digital multy meter
