Help ASAP

[pineway]

I just got done riding my 450, and when i push the throttle to about 1/4 throttle or futher, it boggs down really bad. I cleaned the carb and flushed the gas tank and i cant think of what it could be. What could this be? Thanks for any help.

Is it stock jetting? Does it bog (rich) or cut out (lean)?

[pineway]

its stock jetting, the whole bike is stock. It started doing last weekend at a harescrmable, i cleaned the carb and it still isnt running right.

try taking ur airbox lid off and if it runs right then your jetting is too rich, your filter might be dirty too since it happened at a harescramble, and i know you probably checked already but make sure your choke is off, other then that im not sure

i know u cleaned your carb but it sounds like u got somthing stuck in your main jet or even a little further under the needle;)

Did you check your vent to your gas cap? Also check your spark plug boot to see if its on correct.
