It had a 62.5 low speed jet and a 107 main. It won't rev out to much over plane speed. No power. Smokes like hell. Starts fine. Good spark. 135 ish compression in both cylinders. Anyone? ....Bueller? ....Bueller? ....Bueller?
My best guess would be a 70 pilot and 175 main, that may be a tad rich but better to jet from rich to lean than from lean to rich, I have never a single 38 mikuni on a 650SX
