Hey guys jetting 750SP with 800sxr carbs

Alright here goes. I built a 550/750 conversion a couple years ago and in the beginning I ran a 44sbn and it ran sweet! Now I scored a set of 800sxr carbs for my 750ss small pin and I'm wondering what jets I should run on my setup. Right now it has 150m 80l 1.5 N&S 80 gram spring. The throttle response is nothing like the single 44sbn. The 800sxr intake crossovers are not plugged either. My setup is

750 small pin
650sx Gen3 Coffman pipe
Supertrapp waterbox
Reed stuffers
Milled head
Advanced timing
Lighten flywheel
800sxr dual carbs with prok air filters

I know that my pop off is way to high at around 37psi with free flowing prok air filters. I have a set of new 2.0 N&S I'm going to install to get to around 21psi. The plugs look a tad rich. I also have a question about using a 65 gram spring instead of the 80. I have a set of Novi 42 mikunis that are about the same as the sxr carbs and that set runs sweet on my seadoo! Great crisp throttle response.

LMK what you guys think.

Thanks
Mike
