getting ready to put a pipe on my 450 wolverine and decided against buying a dyno jet kit. just curious what a sensible step is on these carbs. my understanding is it has a 131.5 i think. on my drag car you go in 2 size steps. i.e. if its a 78 and it wrong you go to a 80 or a 76 then back one if it is too much. so i was thinking on this maybe a 135 then a 139 but just wondered if 4 numbers is too big of a step or not enough. thanks
