05 foreman s. i put a hmf pipe, k&n, 170 jet 2 1/2 turns out on a/f screw. ran good but was rich on bottom but would cut off after idleing after 30 seconds or so so i turn a/f screw in to 1 7/8 or 2 ran good. this weekend put on snorkel 1 1/2 pvc all the way, it cutting out bad at top end, feels really flat on top, choke dosent work now either if u pull it out the bike cuts off. help, new to site, love it

i really dont want because i'd have to cut a bunch off plastic. i've seen other people with 1 1/2 pvc and theres seem to run fine on here. just wandering what jet i need to run and where the a/f screw needs to be
