Try searching for a fuel shutoff somewhere near the bottom fuel line exit for the fuel tank on somewhere on the fuel line.

It sounds like its running on the gas in the carburetor and not the gas filling back up to run more, I bet you have a gas supply problem to the carburetor! Try Babbitts Yamaha Partshouse online...

clean tank fuel lines air filter and completely clean all carb parts and jets just did mine runs mint now did the same thing i also put in a new spark plug changed the oil a good once over goes a long way just take your time use a good carb cleaner like crc or gumout and check the jets they have small holes on the sides that can clog up hope this helps

check the engine RPM as well it should be lower than 3600

I have find the service manual with internet:

Standard compression pressure:

400 kPa
(4 kg/cm2 , 57 psi)

I have the same problem, did you find the solution please?

trash in carb take off and clean

That will depend on the charger that you are using. If you use a 10 amp. charger it should only take about two hours for partial charge and up to six for complete. Thank you

Sounds like the rectifier got fried. Moisture in these units is a dangerous thing. Even if you feel the unit sat long enough to dry ouit, it sometines will hold moisture in the electrical componants.

i have the same problem. i took out the air filter and sprayed tb into it and it ran and died. this is the only way to get it to fire up.

i took off the carb, dissasembled it and blasted it out with tb cleaner, took out the jets too, put it all back and it still does the same thing. it is getting fuel but it won't run.

need a profesional answer on this one please.

thanks, tom.
