Clean the carbs

Ditto. was it running before? Anything change since? Anyone change any of the carb settings etc?

+1 on cleaning the carbs.

Did you let it sit for any length of time W/O fuel stabilizer? It doesn't take much for varnish to build up in the jets.

Once you get it cleaned out and running, use a stabilizer(if not already) and also Yamaha's "RingFree". It helps keep the fuel system clean as well as the top end. Works, really, really good.. It'll be the last time you clean the carbs..
