If it were mine , Iwould disassemble carb and check for obstructions.

 

Try putting gas in it

 

The parking brake sensor is a common problem with yamaha quads, i'm pretty sure that's what your problem is. Even if the brake doesn't work the sensor can still cause trouble, it sets a rev limiter just above idle to make it more idiot-proof so people don't ride it with the brake on. Just humor us and unplug the parking brake sensor from the harness, it's the sensor on the perch that has a single plastic connector at the harness end.

 

Yeah, it has no rear brakes. No caliper there. I think it looks like that picture that Speedy2222 posted. My perch does have wires and junk to the little thing that says "parking brake", but they're all disconnected and just wrapped around some posts. Should I unplug it anyway? I took the stuff off the carb earlier and shot some carb/choke cleaner in it, and it seemed like for some reason, that it wanted to run right for about 10 seconds, then start up its B.S. again doing the stalling. Has plenty of gas too, by the way. With the motor not running, if you give it throttle, it squirts out gas fine from the jet, but when its running and you do the same, it doesnt give a steady stream, its kind of a drip. So maybe there is a parking brake sensor effed up or something. What exactly does the connector look like? Is it underneath the neutral/reverse light dash-type thing? Thanks a lot guys!

 

there's 2 white connectors then another one i beleive... 2 of them plug into each other and then the other just stays there... the parking brake cable should be off of there... and leave the cltuch cable.. most people use that..

 

The connector is under the hood in the bundle of wires below the headlight, so you'll have to take the headlight assembly and hood off to get to it. The connector is just a small white plastic connector.

 

Thanks alot guys, I'll let you know how it works out!
