760 drypipe jetting

[superjetkev]

i have a 760, dual oem 44's, factory type 4 and solas j prop. looking for approx jetting specs. anyone with a similar set up? right now im running 115 pilots, 142 mains and 1.5 n/s with dull silver spring. (approx 25 popoff on my gauge) somtimes it hits hard, other times its weak. should i try lowering the mainjet? before when i had 75 pilots it would hardly run. changed to 115's and its much better. the 142's just seem a lil too big. thanks for any suggestions

Go smaller on the mains and use next softer spring (80 gram/black) or also may need to use a 2.0 needle valve as well if still not close with the 80 gram spring.
