I've rebuilt the 3 carbs and my rebuild kit springs cause a pop off pressure around 24lbs. First of all is the correct pop off pressure 10-18lbs as I've found online true? Next is what springs are used to get the correct pop off?

I basically bought a complete sl650 for 200 bucks as part of a package deal where the seller would not separate the 96xp I actually wanted. So I have this thing here. Its in pretty good shape, and I'm ready to get her done and running. I've got the tank out. all the hoses will be replaced. New clunks for the tank. Have a resistor in place of the oil sending unit. Will be running premix and a block off plate.
