Does anybody know what size of seat I would need for a mikuni with an electric fuel pump. The fuel pump I believe is 2 to 4 psi and the carb is a 30mm. I'm on my final stage of completing my upgrades before I bolt carb on I wanna make sure our I have the right seat

I've come across some things I've read and it's either a 1.5 or a 1.7 seat and I think I'm going to get the 1.5 for it. Does anyone have any suggestions on the jets that would go in there I think the stock is a 250 main and 2.0 needle and seat .. it for a molded 23hp with cam and shaved heads
