SOURCE: hi i have a 1984 yamaha moto 4 quad it won't stay

Are you sure you have gas? How long will it run until it dies? If it dies out once it warms up then you have a coil problem. More than likely what is happening though is that you have enough gas to start the engine but the flow rate is affected somehow and the carbs are not able to continue to supply the proper fuel amount. I would suggest rebuilding the carbs.

One of two thing, your fuel shut off isn't working, or is dirty.....
or the float in your carb isn't adjusted, or the needle that the float runs is not seating properly.

SOURCE: my yamaha moto 4 quad

There could be a couple things

1. The throttle cables may be adjusted way and I mean Way to tight (not likely)
2. there is a possiblity the tech put the jets in wrong as the main jet and pilot jet look alot alike on that machine. Only difference is the hole size in the middle of them ( I have done that, thats how I know this)
3 Could be sucking air ( the most likely) from either the intake or the diaphram on the carb. Start the motor and have a can of spray carb cleaner ready to spray and spray the outside of intake and carb if the motor speed changes then it is sucking air.

SOURCE: Hello- I hope you

Did you drain the gas and oil and put fresh in before starting and running? Because if not you could have killed your engine over time gas and oil go bad from sitting. Also maby a new spark plug idk what else maby do a compression test.

Have an 1987 Yamaha moto 4 350 has spark with key off and no spark when key is on

Sounds like you have a bad igntion switch or other electrical gremlin somewhere. If this is something you bought like this, then I would get a service manual with a wiring diagram and ensure the wires on the key switch are in the right positions.
