If I were your buddy, I'd pull the carb and do everything short of a complete rebuild. Have him remove all the jets and soak them overnight in carb cleaner (make a note of the jet sizes and compare them to stock.) Check the needle valve and replace it if necessary. Verify the float condition and level. Check the hotstart and choke to make sure they're not sticking. Replace the fuel lines with some Tygon. With 2 year old gas in the thing, it could be anything or a combination. Also, put in a brand new spark plug and air filter. Then do a filter and oil change.
Once all that's done, retorque the head pipe to the cylinder head, remove and reseal the midpipe and header connection. Check for leaks at all the junctions in the exhaust. After that, provided the bike starts and runs, rejet according to your symptoms. BTW, if your buddy doesn't have a factory manual, that is step number one...SC

Based on what you said sounds like a plugged pilot jet. Take a flash light and look into the tank, if you see brown sludge in it, that stuff is also in your carb.
After cleaning the carb, make sure you clean the tank too or that sludge will right back in a plug the carb again.

sounds like the pilot circuit is plugged up.. .mine did the same thing after sitting for a year..
ISBB (or anyone else),
I'm still learning the basics about these carbs and jetting in general so have questions about this.
By the pilot circuit are you are referring to more than the pilot jet?
Should a guy pull the carb right off the bike in order to do a proper job cleaning it up?

does the carb have to be stripped right down? is there any other suggestions?
