jetting changes due to overbore

[rossthaboss11]

recently got a fresh top end machined to 83mm instead of the 81.25mm setup i had b4. thats the only thing that changed so how will this effect the jetting? it was tuned well b4 with 120 pilot and 150 main and both were 2 turns out i think. Bigger jets? or turn jets our another turn?

Not much in most cases, depends on more if the compression gets too high then a more of a yes answer, Maybe a 122.5 low speed jet, one step bigger.

ohh really. ok ill give that a shot or else just turn my screws out more. how many turns out is to far to where you think it becomes un effective
