seadoo 787 i use stock carb with boring 40 mm and primer kit...I would love installed 90 pilot jet to have a better bottom end with my pipe spec2 factory, be it I keeps main jet 150 or should I drop?
coffman use main 150 pto and mag 145 with 90 pilot...

Is that you think it is a good jetting for factory pipe spec2 or he will run too rich??

calcul point jet!!
jetting factory is 150 main +70 pilot =220 point
jetting coffman 150 main +90 pilot = 240

factory 152 +70= 222
cofman 145+90=235
