760 jetting

[QuickMick]

Im building a 760 for my blaster. I would like some opinions on where to start jetting this motor for the mains and pilot's.

It will have the following:

ADA head 38cc domes around 180 psi 93 octane
84 mm pistons
dual stock 44's
Limited B pipe and water box.

Thats pretty much it.

Thank

Dual stock 44's
Bpipe mod chamber
Pretty heavily ported.

Main 130 H adj 1 turn out

Not exactly the same, but could help I guess.

Im getting good advice telling me to start at different jetting sizes. I dont know what to do.
THanks for the gasket hookup though.
