Best of luck finding the problem. This is why I do not believe in FI on bikes. I have built a couple of carbed EVOs, and they ran fine. And I am an AUTO mechanic, not a motorcycle mechanic. The newer Harley engines have 2 main problems. FI, and the cam chain. Both of which are troublesome, and neither of which are needed. Harley should have stuck with a carbed single cam, but done all the other upgrades. They would have had a bigger, stronger, more reliable motor.
