Nailed the tune on it. It had every mod known to man, way too much compression for 6 heat range plugs too! Going to 8 heat range and adding a PCIIIusb on top of the horrible MG Racing ECU made a night and day difference. One of the oddest maps I have written to date, 60-80-100% TP were all totally different levels of fueling. To make any real power it would have required larger throttle bodies, they were definitely the choke point for power on that motor. When the owner took it for a test ride before paying he came back with a huge smile, I knew he was thrilled with it.
Best compliment from him was, "it runs like a properly carbureted bike now, like a well tuned stock bike whether at 1500 or 7000 rpm! Fueling had to be artificially rich in a few places to keep detonation at bay but being air cooed this is acceptable.
