Have you check the choke position?
When you got it going does it rev up high immediately, if yes then you choke is stuck wide open.
Good enough?

I start my Yamaha Banshee 350 ATV, it starts fine and idles fine but when I start riding it and gets a bit over half throttle it starts backfiring really bad. Any suggestions on what to look for? TIA

Question edited for FULL 'make model (what it is)', from 'banshee'.
Question moved from Motorcycles to correct Category.

Check spark plugs.
Clean Carb.
Check timing.

More here, it is a known issue.

Why is my Yamaha Banshee is hard to start

It looks like your compression is too low (worn rings from dusted motor) Push starting spins the motor faster than kick starting and when hot the rings expand just enough to seal off. Before kicking a cold motor try putting in a squirt or two of engine oil in the plug hole to see if there is a difference.

Yamaha banshee will not start

Did you accidentally cross the spark plug wires?
Other wise its going to be hard to diagnose,
Do you have plenty of compression,
Are you getting gas to the spark plugs?
Is the air filter clean/new?
You will need a factory service manual to diagnose further if all the above is ok

My 80 cc sputters for a couple seconds then clears up under throttle.doesn't matter what gear I am in even nuetral.could it be bad gas?

could be bad gas but my banshee did the same thing and i replaced the reeds and she screamed again try some fresh gas a new plug and new reeds also check out the needle and seat in the carb as i have had bikes act this way and they cleared up with a basic carb rebuild

Banshee running wide open after a couple of revs

The problem with vents is that a vent can get plugged and lessen or completely kill the flow of fuel. They will not make an engine rev wildly. Your banshee has standard carbs. The throttle cables may be routed incorrectly, pinching or stretching the cables. Remove the air filters. Look inside the carbs. Do the slides move freely up and down when the throttle is twisted? In the diagram below note the junction tube on the throttle cabel. The cable can stick at inside the tube. Is the connector hose between the carbs in place? Also, there is a switch on top of the carb. This can go haywire also. Odd that the problem was not present before they cleaned the carbs.
Can I get a “very helpful” rating on this answer?
