Super Jet Sn carb question

[Flameoutgarrett]

So I have a 90 sn and my stock carb is pretty much toast, bought as a project and everything on the carb is hammered out. so my question is this, I want this ski to be a river ride, is there a smaller carb I can use for better Milage without sacrificing too much power? My 650sx chugs fuel and doesn't get me very far on the river runs

Superjet is bone stock with the exception of rideplate, so if anyone has any ideas on what I can use lemme know

Thanks

Adapt an SBN 38 and lean to peak power for best fuel economy. Your 650sx must be set excessively rich because they usually have the longest legs of all skis.
