i went with this setup

Main Jet: 135
Pilot Jet: 75
High speed screw: 1 1/2 turns out from closed
Low speed screw: 1 1/4 turns out form closed
Needle & Seat: stock (55 psi)
Spring: Stock (95 gram)

the top screw only open is max bottom end at the cost of more moisture in the motor per my builder...builder says run middle screw only open one half turn....the top screw is above (higher) than the exhaust manifold and close to the manifold so some water gets into the motor at times...

Too much prop.

95 gram spring is NOT a stock spring!
A 115 gram spring is. Well at least in U.S. Superjets. (all years)
They were always gold, but now they are chrome color, last 2-3 years or so from Mikuni

even factory pipe says the stock spring are 95 grams.
