I have a 74 ironhead, bought as a basket case. Got it almost done, but i'm having misfire issues with the front cylinder. It will only fire under wide open throttle, other than that it it doesn't fire. The motor is fresh, .040 wiesco pistons, heads were done, new valves, ground seats, new guides. New points, gapped correctly. Valves are adjusted correctly, checked and rechecked cam timing. I'm running a 38 mm mikuni, 310 main jet, 30 pilot. i have a custom intake built for it, it comes off the motor, turns 90 degrees forward and runs about 4 inches towards the front of the motor and the carb is clamped to that, is this my issue? I would think it would affect both cylinders not just one. My coil tested fine, even tried a known good coil off a buddies bike, nothing. Someone please point me in the right direction!
