is it carbureted or fuel injected? are your warning horns working? if it iscarbureted then a few easy test can be done to find out. if its fuel injected then its a little harder but not impossible.(1) check compression. without the year model I'm giving you a average numbers. all cylinders need to be over 100 lbs and equal each other within 5 lbs.(2) check spark. use a spark gap tester all cylinders should jump a half inch gap. if you have good compression and good spark fuel is the problem nine times out of ten. clean fuel lines replace primer bulb and replace all fuel filters. Yamaha has a gravity filter under the engine coul. take it to the lake if no improvement. clean carbs. same test to be and fuel system service used of fuel injected engines. if no improvement in engine preformance then you will have to take it to a dealer to test with computer.
