    Either jetting or an intake leak would cause that. Has it always don it?

    If it's a flat bog right off idle, it sure can be the accelerator pump. I have seen,
    (not on HD but on Yamaha Mikuni) where the linkage to the pump was slightly worn and the initial slack take up of linkage would create a bog right off idle. If you could be cruising at 1/4 throttle and nail it to WOT with no bog, it supports the theory of the accelerator pump not have a sufficient shot of fuel.

    I have never worked on a HD carb. Just going by some metric experience.
