i would get the carbs cleaned..I have a 94 Kawasaki that starves for gas when opening the throttle, then dies and wont always restart. Changed the fuel pump, checked the fuel cap, adjusted the choke valves, I don't know what else to try. It runs great when it is running. I have had it about a month. The first 5 or 6 times i took it out it was hard to start but ran good after starting. And would run most of the gas tank out each time.
