Rephased XS650 with Jack's D-Shaped Intake Ports!

700cc with JE Pistons, 277 Rephased Crank, Early Camshaft, 277 Pamcopete Ignition and all the normal goodies we do to an engine at Hugh's HandBuilt. All but 1 exception. We spent the last few months with "Jack" from the forums, and he's taught us a TON of new ways to get some flow into the heads on these engines. This particular engine has had the intake runners "D" Shaped, with a raised floor and some healthy 2nd turns, and slightly shrunk in diameter to raise velocity. Very special thanks to Jack for taking the time to hang out in the shop with us, and show us a few tricks!
