well, for you guys that run lean jets, what is all that other stuff you ajust. i live a sea level and run my wr in the dunes pinned alot. i run a 45pilot with a 178 mian and the P needle 4 down. i also have it yz timed all the wr crap off it with a full WB system open with no disks. could it be that there is a huge difference in everyones jetting do to where they ride and in what conditiones. would you guys running 160 mains take them out to the dunes with a paddle at sea level and runn them wide open all day?
