i have a 01 raptor with a full graydon exhaust, pro-flow kit with foam filter, no airbox lid, 160 and 165 main jets, and needles set on 4th from top. the pilot jets are stock. at low rpm with a load on it, it will cut out and die. to start it i have to turn the choke on slighty and hold the throttle about 1/4 open. my guess is i need bigger pilot jets. any suggestions would be great. if it is pilot jets then what size should i go with? btw, elevation here is about 1200 feet, if it helps.
