Check the reed valves 1 is probley broken if it is baackfiring thru the carburetor.
The engine backfiring at idle, and at slightly off idle speeds is indicative of a lean fuel/air mixture. Try enriching your fuel mixture.
If it is a stroke emty some of the gas and add some more gas
Probably. Backfiring is a symptom of a lean condition. Wouldn't want to leave it like that.
I would suspect it is not timed correctly.
Sounds like the throttle sensor, throttle body needs to be replaced.
my guess would be that the ignition timing is off, but it is really hard to tell without actually looking at it an listening to it.
sounds like the tineing belt.
If your Yamaha TTR 250 starts but keeps cutting out after a fuel minutes, it might not be getting enough fuel. Check to ensure the fuel line is not clogged.
if its a 2-stroke the governer is a little black block that keeps the throttle from opening.so watch the throttle on the carb as you slowly open it.just remove about half of it though or else the throttle will start to close again

Ease up on the throttle while cornering.
