The v-twin is more sensitive to air flow than most motors. If you snorkel, you have to rejet. It isn't really hard. I would get a dyno-jet kit. Use the stock needles with two shims on each each needle. Run the dyno-jet springs and I would start with a 122 front main, and a 124 rear main. Mixture screw about two turns out. Should be pretty close.
