Jetting Sbn 44 for x2

[Turkey Roasta]

I have x2 with a high comp head (175psi) stock exhaust and im trying to figure out tuning sbn 44 for this set up. Getting too much fuel right now mostly trying to figure out what to run for popooff spring, and jet recommendations?

Try a gold spring. Generally speaking, single 44s require pilot jets in the 120-130 range with popoff around 30 psi. Main jets usually 150-170, change mains until the top adjuster is around 1 turn out when max full throttle rpm is achieved.

150 main, 120 low, 80g spring, 2.0 n/s

I had the same question so I searched forums on here and documented what everyone was saying/recommending. Everything came back as:

Main: 140-150
Low: 115-120
N/S: 2.0
Spring: 80g

Start with a 2.0 N/S and 80 g spring and somewhere within the range shown on main and pilot jets and that'll get you pretty dang close.
