I just had my 02 heritage top end rebuilt, it has a stage 3 screaming eagle kit installed with V&H strait pipes and drag injectors. I bought it that way, however now its runing like crap, like its starving for fuel and I can hear a ping when I get on it, I already did the break in on it and took it easy on it for the first 1000 miles so I know its not the pistons, what I would like to know is if the timing is suppose to be different for the screaming eagle than on a stock 88, which I think is where it is set. Please help.
