Can anyone please help. I have a 750 SXI with a 44mm SBN Single Carb with a factory wet pipe with the limited chamber. Also am running a 10/16 Skat Trak Swirl Prop.

I what to know the proper spring gram size, N/S size, Pilot and High Speed Jet sizes that are proper for a factory limited pipe. Also a good pop off pressure to shoot for. Any help is greatly appreciated.

My carb currently has:

2.5 N/S
80 Gram Spring
(I'm assuming with this spring and N/S combo this puts me at 14 psi pop off per the mikuni manual)
107.5 Pilot Jet
155 High Jet

Currently my throttle band is completely insane, ski from idle to half throttle has low rpm's, and then suddenly at right over half throttle the engine will rev like it as at wide open throttle and ride like a raging bull. Trying to obtain a normal throttle response throughout the powerband...

Scott.
