my 450 will only run with the choke on, if you turn the choke off and keep it running with the throttle it pops and cuts in and out, it also sounds like it gasps for air at idle like a hick up almost.....the motor is stock i have an 08 head pipe (fatter diameter) and white bros xcr muffler, my airbox lid is half open ( i cut out half of it) and if i remember correctly i re jetted it with an 088 main and didnt touch anything else, im guessing its not getting enough fuel but before i go digging in i could use some good as advice, thank you in advance!
